After much discussion, consideration and research, we made the decision to purchase an all-electric car. (We test-drove both the Nissan Leaf and Chevy Volt back in 2010.) This purchase was made with full understanding of the pricing, the 7500$ Federal rebate, the sales tax exception for electric cars in WA State, and awareness of the limited range of about 70 miles between charges.

Our new car – The 2013 Nissan Leaf ‘S’

The car we purchased was the 2013 Nissan Leaf ‘S’ model. This is a newly-introduced model with a few less bells and whistles than last years car (ex: no navigation system), but a much more palatable MSRP of 28,800$. After factoring in the 7,500$ Federal Tax Credit, no sales tax (for electric cars) in Washington State and by negotiating the price, the car costs less than 20,000$. (The tax savings make it comparable to a gas-powered car costing 18,000$.)

For the price, you are still getting some higher-end features including keyless entry and start – if the key is in your pocket, that’s good enough to turn on the car. Even without the higher-end navigation features, the ‘S’ model has AM/FM/XM Radio, a perfectly reasonable sound system and Bluetooth hands-free for making phone calls. Besides, most people have a cell phone with navigation capabilities, and this isn’t a car you are likely to take far from home. At the lowest price, you are foregoing the ability to charge the car twice as fast (6.6kW/hr) when plugged-in to a 240v “level 2″ charger or even faster using a “Level 3″ charger, but this is available as a 1300$ upgrade if you need this ability.

Since we rarely drive more than 30 miles in a single day of commuting, we planned to simply charge the car at home with the slower 120v charger which is included with the car.

Owning an Electric Car – The Missing Manual (Pacific NW Edition)

Even if your electric car purchase is well researched, an electric car is a paradigm shift and it takes some adjustment. Even in the Pacific Northwest, electric cars are uncommon, and you will experience the growing pains of a new industry.

1: Comparing the cost per mile to Gasoline

One of the key selling points of an electric car like the Leaf is the potential savings when it comes to cost per mile. It is pretty easy to compare the cost to drive a mile with an electric car and a gas-powered car. (In these calculations, I am excluding other costs of ownership such as oil changes and regular servicing which should be less for an electric car.)

Leaf vs. Prius

Nissan Leaf
The Leaf gets about 3 miles per kWH. At a cost of 8 to 9 cents per kWH in Seattle, the cost per mile is 3 cents.

Honda Civic
While the Honda Fit may seem like a better comparison to the Leaf, I’m being generous and looking at the Civic which gets a little more MPG. With 32mpg and an average price of 3.5$/gallon (It’s currently 3.75$), the cost per mile is 11 cents.

Toyota Prius C
The Prius C is their new entry-level hybrid car, and is almost exactly the same cost as the Leaf after you account for the federal credit and no sales tax. It is smaller than the Leaf and not as nice. That said, it’s the lowest priced car which gets 50mpg. At 50mpg, the cost per mile is 7 cents, still more than twice that of the Leaf.

I also considered the Plug-in Prius and some other electric car options, but they were less cost effective and less appealing.

Total cost to drive 100k miles
The following shows the total cost to drive each car 100,000 miles, which is how far I expect we will drive a commuter car in 8-10 years.

Leaf = 0.03*100,000 = 3,000$ + 20,000$ = 23,000$.
Civic = 0.11*100,000 = 11,000 + 18,000$ (car + tax) = 29,000$.
Prius C = 0.07*100,000 = 7,000 + 20,000$ (car + tax) = 27,000$.

These calculations don’t take into account:

The value of the car at the end of 100,000 years. – I cannot predict the value of the Leaf in 10 years, but I believe it will be near the value of a Prius or Civic.

The cost benefit we would receive by owning a more efficient car (than our Subaru Forester) which does not have the 70 mile range limit. – I can definitely say that a Civic or Prius would have given us a modest savings every year, as we would probably take it instead of the Subaru on a couple of weekend trips. A fair guess is a couple trips each year totaling less than 1000 miles roundtrip, which would cost 130$ in a Subaru and 70$ in the Prius C for a savings of 60$. Over 10 years, we might save 600$ in this manner, but it doesn’t approach the larger savings we enjoy in driving the Leaf on a daily basis as our commuter car.

Preference towards a particular car and it’s features. – I tend to make major purchases based on facts and predictions rather than emotional factors, but let’s be real, nice things are nice. The Leaf is not a “fancy” car, but the interior and features are of a higher-quality than the Prius C, which they clearly stripped down to reach a price point. While the Civic is a comfortable car, we definitely felt like the Prius C was awfully crowded.

As you can see, the Leaf made the most sense for us based on our needs and a detailed cost analysis.

2: Demystifying charging options

In practical terms, a Leaf can drive about 3 miles for every kWH of power stored in the 24kWh battery, for a total range of a little over 70 miles. In other words, it is much faster to deplete the battery than to charge it!

A Level 2 Charger

Level 1 Charging is what you get when you plug an electric car into a standard 120V electrical outlet. This will recharge your car by 1kW per hour. (In practical terms you can drive 3 miles for every hour it is plugged in.)

Level 1 chargers are limited by standard household wiring and circuits which are generally rated for 15A, which would allow a theoretical 1.8kW of charging. (Watts = Amps * Volts, therefore 15A * 120V = 1800W.) In practice, a car plugged in to a Level 1 charger should expect to recharge about 1kW per hour since these chargers generally only utilize 10A. (There may be other outlets in the circuit which are in use.)

Level 2 Charging is much faster allowing you to charge your car at a rate of up to 6.6kW/hr, Our car is limited to 3.3hW/hr, which in practice means about 10 miles of driving for each hour of charging.

Level 2 Chargers rely on the same 240V electrical output which is used by large appliances such as dryers and ovens. Most level 2 chargers allow cars to charge at up to 6.6kW/h, which is made possible by the use of a 30A 240V circuit. (This has a theoretical output of 7200W based on the same equation. Some homes are actually wired as 110V/220V, which would have an theoretical limit of 6600W on a 30A circuit.)

After only a couple days with the car, we are considering a level 2 charger at our house. There is a 30% federal credit to buy and install a charger, which should put the cost under 1000$.

3: Charging ‘Networks’

Living in the Pacific Northwest, you have probably seen special parking spots for electric cars at the store or at the mall. One might naively assume that these charging stations are free to use as an incentive to shopping at that location, and in some cases you would be right, and in other cases you would be badly mistaken.

charging networks

As it turns out, the vast majority of public charging stations have been built with the ability to charge based on a fixed rate for each hour or for each kW of charging. Unfortunately for electric car owners, very few of these stations simply take a credit card like a gas station. Instead, you must become a member of their particular “charging network” in order to recharge your car. (ex: Imagine if each gas station required a special credit card that only works at their gas stations. If you desperately needed gas and the nearest station was of the wrong type, you would be unable to fill up your car.)

Thankfully, in the Seattle area there are only two major networks which cover the majority of charging locations. If you want the flexibility to use these stations due to unexpected changes to your driving plans, you will need to create an account with both networks and carry multiple RFID cards to use any charging station you might encouter.

ChargePoint has 11,096 charging stations nationwide (at the time of this article). They leave it up to the station owner to determine pricing. Some stations are provided free of charge to ChargePoint members (ex: City of Kirkland or Bellevue), and others have fees ranging from a fair price of 2$ for up to 12 hours at City of Seattle to an outrageous price of 2$ per hour at Bellevue Square Mall. Chargepoint also has an annoying policy where you must make an initial deposit of 25$ before you can use any stations with a fee. This makes it hard to justify as a solution to only use as a backup.
Blink Network has 1252 charging stations nationwide, and many of these stations are located in Seattle and Portland. All Blink stations offer the same pricing of 1$/hr for members and up to 2$/hr if you are not. Their membership fee is 30$, which doesn’t include any charging at all, but the fee is being waived at this time for new customers. This pricing is very poor for people like me who can only charge at a rate of 3.3kW/hr. (At 1$/hr they are charging 30 cents per kWh, versus 9 cents per kWh at home.)
There are a few more networks which may be useful if you venture outside of Seattle or Bellevue such as AeroVironment, who has stations in Snoqualmie, Burlington, Skykomish and Leavenworth. (I believe these stations are free, but I’m not sure.) Semacharge stations are installed outside 17 Walgreens stores in our area, but all SemaCharge are currently free and do not require a membership. OPConnect may be relevant if you want to visit Portland.

4: Living with limited range

With a gasoline-powered car, you have the luxury of only looking at the gas gauge every once in a while. By contrast, you need to pay close attention to the battery level and projected range in an electric car. This can cause some drivers to develop range anxiety.

In our limited experience, it seems like the easiest way to manage the limited range is to consider your whole trip before you leave the house. In our case, I have a 6 mile (each way) commute and my wife has a 11 mile commute (each way). Since either commute is well under 25 miles total, we have 40+ miles of wiggle room to add a trip to the gym, to the store, or other unexpected destinations. In the rare instance where we need to exceed that range in a single day, we would leverage one of the many free or paid charging options called out earlier. We own two cars, so we can always switch cars if we need to drive further than that in a day.

I plan to offer more details of our experience living with an electric car sometime soon. If you have any comments or questions, leave a message below!

ADDENDUM 3/7/2013: I have received some clarifying information on both the circuitry required to install a Level 2 Charger (it should be a 40A circuit) and the energy loss associated with charging a battery which needs to be factored into costs and calculations. I plan to update this post later to clarify a few of these details.

Understanding Niche Online Communities

February 20th, 2013 by Tom Alphin No comments »

A lot of attention paid in recent years to the big online social media sites such as Facebook, but some of the most interesting destinations on the web are those websites dedicated to a single topic in great detail. This narrow focus allows people around the world to connect with others that share their niche obsession.

These niche online communities cover a broad range of topics, including knitting, discount shopping, books, movies or beer. Some sites support thousands of users and a broad topic, others have a very narrow audience. (Ex: a site dedicated to all board games vs. a single board game.)

This article explores the history of niche online communities, recent trends and some of the unique challenges these types of sites face.

Message boards – simple online communities

The simplest online communities are little more than a forum where users can read the posts made by other users, provide their own comments to further the discussion or start a new “thread” to explore a new topic. As communities grow, they tend to use folders to organize conversations into more specific areas. This type of online community is not a new concept – they preceded the world wide web itself as usenet which started in 1980 and BBS Systems. Even the earliest electronic systems were preceded by niche publications, newsletters, zines and journals.

NWHikers is a simple forum dedicated to hiking in the Pacific Northwest.

Numerous free and paid solutions make it easy to add a message board to a website with limited technical skills, such as MyBB, SMF and BBpress.

Communities around structured content

Many strong communities form around broader topics which can be broken into atomic units that can be indexed, categorized and searched. For example, a website for people who enjoy good beer might have entries for specific beers, specific breweries or specific styles of beer. Since people often search for the name of a specific topic using a search engine, websites that offer detailed information about a specific topic can draw in new visitors since an entry in a well respected online community is often the most relevant result.

Databases
From an implementation perspective, this type of structured content is generally stored in a database using a strictly defined schema. Schematized data can be defined in many different ways including the now-ubiquitous XML format. For example, each “beer” could be represented as a separate entry in a database with columns containing information like the “name” of the beer, the “brewery” where it is brewed, the “style” of beer and more.

A community can offer many ways to find new things, such as this view of the most popular English Brown Ales on the BeerAdvocate site.

Well-designed websites around this type of structured data can be very interesting to browse, especially if they employ extensive hyperlinks. A user who enjoys “Newcastle” beer might click a link indicating that it is an “English brown ale”, which could display a list of beers of the same style. It is often possible to sort these results in interesting ways to find another beer you want to try, such as sorting by popularity to find some of the best examples of the style, or filtering by location to see other English brown ales you should try which are brewed near your home.

Community-generated content
It is a lot of work to build a large, relevant and accurate database of information, which is why many websites allow visitors to submit content and make updates. This may go through a review process to ensure the integrity of the data. Beyond the main entry for an item in a database, many communities allow visitors to submit images or other content to share with other members of the community.

Editorial content
While community-generated content can be very valuable, some sites offer editorial content which is either created by the site administrators, or a curated view of the best user-submitted content. The advantage of this editorialized content is that the site can present more consistently high quality content, especially on high-profile pages like the homepage which may be a new visitors first experience with your online community. Recent trends towards simpler, more elegant, photographically rich websites often require purpose-made editorial content to fit more rigid layout requirements.

Trends to engage your community

Successful online communities understand that they play an important role in their visitors lives, and want to encourage regular visits and meaningful contributions by visitors. There are several tactics which sites employ to get visitors to come back and stay awhile.

Collections and reviews
When a website has structured info on a large collection of items, it is a natural extension to allow visitors to use the website to keep track of their collections and experiences. The community might allow members to keep track of something they are collecting or keep track of experiences. Allowing members of the community to enter ratings can be a great way to get people to come back and record their impressions. They may do this for their own satisfaction, to have a record of their favorites that they can refer back to, and they may also offer ratings because they want other members of the community to discover things which they enjoyed.

IMDB relies on ratings provided by their members.

IMDB relies on ratings provided by members to offer a list of the “Top 250 Movies”.

Gamification
Successful niche online communities keep visitors coming back and contributing. Most sites reward return visitors by having new content, but many sites are exploring additional ways to bring users back.

The BoardGameGeek website encourages users to make meaningful contributions to the community by offering a virtual currency, ability to give others a "thumbs up", and recognizes users who donate money as "patrons".

The BoardGameGeek website offers many ways to highlight their best members.

Gamification is when game-like motivations such as our desire for rewards are applied in a non-game setting. These motivations can encourage community members to behave in a desirable way. This could range from small incentives to complete a detailed user profile with a user tile image and the city where you live, to larger incentives and recognition for contributing valuable new information to the community. Incentives might include public recognition, achievements, points and fake currencies. Some sites have even explored cash rewards or prizes.

Anonymity
Historically, most communities have allowed members of the community to participate using an “alias” which is largely anonymous. Successful communities develop well understood rules of etiquette, and it is not uncommon for members of the community to fight back when one member behaves poorly. That said, people are still more likely to behave inappropriately in online communities when nobody knows who they are.

There seems to be a recent trend towards more transparency in many facets of the world including social networks, which are increasingly encouraging that you provide a personal photo and your real name to participate in the community. This can minimize “trolling” (being nasty to others in forums) and other poor behavior which can happen in a truly anonymous community. When community members expose their true identity, they may be more likely to make valuable contributions.

Integration with broader social networks
Another trend of niche online communities has been to integrate with broader social networks such as Facebook. This is seen as a benefit for many community owners as cross-referencing to a broader social network could generate traffic to their site. Niche communities need to be careful though – they run the risk of alienating their existing members if they misuse their public social network by spamming their friends which may not care about this niche topic.

That said, a well behaved niche online community can still offer clear benefits to their members who connect their experience to a broader social network. For example, instead of spamming all of their friends, it may be more meaningful to highlight your friends from a mainstream social network who also use this niche community. Discovering that a friend shares your interest in a particular niche can lead to a richer relationship with that person.

Looking forward
Niche online communities have a lot of challenges ahead of them. They need to keep up with trends towards more elegant, well designed websites to attract new members. This can be difficult, as advertising is critical to supporting the community, but poorly integrated advertisements degrade the experience for visitors. Integrating more advanced capabilities into a community can be time consuming and costly, such as enabling high quality search experiences for your proprietary data, and enabling connections to mainstream online communities like Facebook. Many communities are also feeling pressure to develop applications to access their content more efficiently on mobile devices.

There is definitely an opportunity for easy to integrate modular solutions which allow small communities to expand to include well-designed experiences around structured content, enable community engagement features to reward and recognize valuable contributions, and to integrate thoughtfully with mainstream online communities. In the process, niche online communities must recognize that they exist to fill a narrow niche, and expanding the scope of the community may result in a less valuable, less focused community.

12 years, at least as many digital cameras

April 27th, 2012 by Tom Alphin No comments »

I’ve been interested in photography in varying degrees since middle school. Over the years, I’ve had a handful of disposable film cameras, a decent Olympus 35mm point and shoot (with a zoom) and the opportunity to use my parents Olympus OM-1 camera with a variety of excellent prime lenses. I was even fortunate enough (because I am just old enough) to have had the opportunity to take an enrichment program in high school and a photography class in college that both involved taking photos on black and white 35mm t-max film, processing that film and making my own prints in a darkroom.

That said, my enthusiasm for photography skyrocketed with the introduction of cost effective Digital Cameras. What follows is a brief look at the many cameras which have passed through my ownership in the ongoing quest for the best camera I could justify purchasing.

2000 – The hook

1998 was the first year I saw a fellow student who owned a digital camera. (I think it was Nick Vitalbo) It was interesting as a piece of technology, but since it wasn’t my own, it didn’t really stick in my mind. Clearly something piqued my interest, as I bought a very cheap digital camera with fixed memory and a proprietary image format that holiday before returning to school.

It only took a couple weeks before I was hooked, and made my first upgrade to the Fujifilm DX-9. I upgraded three more times that year, finally sticking with the Nikon Coolpix 950, a sharp 2 megapixel camera with a unique swiveling design. If those first cheap cameras were what got me hooked on taking (and sharing) photos of my friends and various adventures, it was the 950 which got me excited about taking better photos.

2001 – The art

After a year with the Coolpix 950, I was still enjoying the camera’s design, but wanted higher resolution images. I made the natural upgrade to the Coolpix 995, a superior model of the same basic design. This took me through the end of college and was my main camera for the next 1.5 years.

2002 – On the go

The only limitation of the Coolpix design was size, which is why I picked up a Canon s200 pocket camera as a second camera. I was never quite satisfied with this camera, and ended up upgrading my pocket-sized cameras five more times over the years, never quite satisfied with the results.

2003 – RAW and post-processing

In 2003 I bought my first camera capable of capturing images in the camera’s “RAW” format, such that I could make the creative processing decisions later on my computer. This was a huge catalyst for paying more attention to my art, even though the initial tools were very limited in their post-processing capabilites. The eventual release of Adobe Lightroom in 2007 finally gave us quick and easy post-processing capabilities.

Bighorn Sheep - Jasper/Banff National Parks (Canon G3)

2004 – Digital SLR

By 2004, I wanted more than I could get out of a point-and-shoot camera. I had known for a while that the next step would be to purchase an Digital SLR, and Canon made this remotely affordable when they released the Digital Rebel / 300D. I immediately started taking better photos, and loved the flexibility additional lenses opened up to me, as well as the richer post-processing capabilities it offered.

Hetch Hetchy Reservoir - Yosemite National Park (Canon 300d / EF-S 18-55mm)

2007 – HD Video

While second to my fondness for photography, I also enjoy capturing short videos, predominantly while traveling. In 2007 I picked up the HV10, a camcorder which shot HD video on familiar and readily available Mini DV cassettes. The next year I upgraded to a similar camcorder which stored video on SDHC cards and was less hassle to import and use.

2008-2010 – Sharing the fun

As I got better, I got better lenses and the cameras got better too, I wanted a camera with more resolution. I upgraded to the XTi in the spring, and by the fall Amy was ready for her own SLR too. That Christmas, I got her the XSi camera, and she got me the excellent Sigma 30mm 1.4 lens. She quickly took to photography (and it made it easier for me to justify camera gear purchases).

Orondo Cider Works - Lake Chelan, WA (Canon 300D, Ef 35mm F/2)

2011 – Better pictures on the go

After years struggling with terrible pocket cameras, we were so happy to get the Canon G12 for Christmas. It is a point and shoot with the manual controls “photo people” can’t live without. It has been our companion on many short trips where our larger cameras aren’t practical or feasible.

Appalachian Trail - Cole Mountain (Canon G12)

2012 – Taking it to the next level

Recently, I’ve been catching up on processing my photos, and I’ve been putting more attention into my compositions and my craft. Among other things, I love taking panoramic photos, as they capture the breadth and wildness of the many outdoor places we visit. I’ve recently recognized that I have hit the limits of my gear, and am excited to have just purchased a used Canon 5d mark II camera. I will certainly need to update a few lenses since a couple of our lenses aren’t compatible with a full frame camera.

The new camera will allow us to get some more capable lenses especially on the wide end, leverage advanced metering and focus capabilities, and take better photos. I’m excited for the increased sharpness and better source material for stitching panoramic images, and Amy is excited to have a more powerful camera to use for event photography.

Sunrise, Aguereberry Point - Death Valley National Park (Stitched Panorama using Canon t2i / EF-S 10-22mm on a tripod)

Table of cameras I’ve owned.

No, I don’t think very many people will actually find this interesting, but I found it helpful in understanding just how far we’ve come in so little time.

What makes this fun? A critical look at several board games.

November 29th, 2011 by Tom Alphin No comments »

One of the (few) things I love about the transition from warm sunny summer days to cool rainy fall days is the opportunity to play my favorite board games, and find new favorites. As I’ve gotten more into the hobby, I’ve continued to scour Board Game Geek for new games to try. As I play more and more games, I’ve considered trying my own hand at making a compelling board game. (Conveniently, a new avenue to get your game published has appeared: Kickstarter, which lets you market your idea and allow folks to commit to buying your product so long as you achieve the minimum dollar amount in investments.)

To aid in this process, I’ve started to look at the games I play with new eyes: trying to identify what makes each game fun. (I’ve found that even games which I don’t prefer overall can have a design touch, or an interesting game mechanic that I find particularly fun.)

Settlers of Catan – the chance to win from behind…
As this was the first Euro-style Board game I ever played, it seems fitting to look at it first. While it may be an imperfect game which relies too heavily on the luck of the dice, it is definitely one of the few games I’ve played a lot where you can come back from pretty far behind and win. This is achieved by recognizing that several elements of the gameplay are built on luck, and you can bet against the odds for a chance to win.

Building settlements on a couple unlikely numbers. (If you are losing, why not bet on 4′s… If they are rolled more often than usual, you can grow when your opponents get nothing.)
Development cards. They are rarely bad, and the chance of a Victory point card for just three resources is the best exchange rate in the game.

Not so great: Of the games I play somewhat regularly, Settlers is the least fun game to lose. It’s too easy to blame “bad luck” for a loss, and it is possible to get cut off early in the game such that you know you are going to lose an hour before the game ends.

Carcassonne – simple core mechanics leading to an ever expanding game…

Carcassonne is ever expanding for two reasons: 1) outward growth, as each player adds tiles to the game board is the core game mechanic. 2) The simple core mechanics have led to nearly 20 expansions which add tiles and rules to the game, as well as numerous standalone games based on the same basic game mechanics.

I find an elegance in those games which can be easily expanded upon without breaking their essence – usually the core game mechanic that propels the game.

Carcassonne is easily expanded since you just add more tiles to the deck with new abilities and shuffle them all together.
Deckbuilding games (like Dominion) are similarly expandable, as the draw/discard pattern can be preserved while adding new cards to the mix.
Ticket to Ride can be expanded by providing new maps/routes while preserving the balance of collecting cards, claim routes to complete tickets and drawing more tickets.

Many of the other games I enjoy are less obvious to expand upon because the game is built on the ability to take multiple actions which have been carefully balanced against one another. This is particularly true of popular “worker placement” games such as Agricola or Puerto Rico. A rich expansion to either game is difficult to achieve without changing the game’s essence. (Puerto Rico’s expansion have simply added building types and has little appeal, and “Farmers of the Moor” the only major expansion to Agricola added an awkward new type of action to make up for the new burden of heating your home.)

Race for the Galaxy – One game, many roads to victory…
Race is unique in many ways, notably the manner in which cards in hand are valuable both in the abilities they provide and their use as currency to buy other cards. Race is also rather unique in that there are so many ways to win the game. There are strategies that involve producing and consuming goods to get victory points, developing many of one type of card to maximize bonus points from the various 6-cost development cards, strategies to end the game quickly to prevent opponent from accruing too many points, all while using some combination of military, exploring or trading to fund your growth.

I’ve played more games of Race for the Galaxy than any other game we own. This is due to the many ways to win, it’s strength as a two-player game, and the compact game size with no fixed board (which makes it easy to travel with).

Not so great: Race for the Galaxy also happens to have one of the most complex and cryptic set of icons of any game I’ve ever played. This is why we have rarely played with more than two players – the game is incredibly difficult to teach and the first couple games aren’t much fun. (The game would be a lot easier to teach if it had better icons and/or relied less on icons in favor of text.)

A few more noteworthy games:

Dixit – I’m having fun even when I’m losing…
This is a game we just got, but so far I enjoy the beautiful artwork and the creative gameplay which rewards a clever player. That said, it is nearly as much to see who scored points during each round as it is to win.
Dominion – Tipping point…
I already mentioned Dominion as one of the great games when it comes to expandability, but my favorite element of the game is an invisible one… In this game, there are two phases of play, but no clear distinction between them: building your deck, and acquiring Victory Points. The player who prepares the best deck and is able to shift focus to acquiring victory points at the right time wins. If you switch focus too early, your deck will get diluted with victory points and lose effectiveness while others get more points overall. If you switch too late, you won’t have enough time to get a winning score.
Galactic Emperor – Political influence…
This is the only “4x” (explore, expand, exploit, exterminate) game I’ve played, but it had a noteworthy game mechanic that I really enjoyed. When the “influence” action is selected, each player can place two tokens (and may buy a third) to conquer planets with political influence, or defend against the influence of other players. The advantage of going last is significant, since you can defend against the political attacks others made, and take over other planets without contest. You must exert your power with care, since everyone has roughly the same amount of influence. (2 or 3 tokens)

What’s your favorite game, and why? Or, is there something about a game which you really like, even if the game isn’t that great overall?

Day 1: Bike Commuting.

October 10th, 2011 by Tom Alphin 2 comments »

I’ve been riding my bike to work a lot this year, initially on my trusty old mountain bike, later on my new (and much more efficient) road bike. Riding to work on a sunny day is a great feeling, plus you can turn a 15-20 minute commute in traffic into a 30 minute workout.

Getting Ice Cream (Molly Moons Truck, no less!) at the end of my first long ride. - This is the opposite of Bike Commuting.

I’ve also taken a number of long rides this fall, all on my new bike: The first one with Brendan around Mercer Island, across i90 down to Seward Park and back. A second long ride was also with Brendan, from REI in Downtown Seattle to my house in Kirkland, mostly on the Burke Gilman / Sammamish river trails. (and yes, the Lake City reroute sucks.) The last one was by myself – from the house to Safeco Field for the Microsoft company meeting, also north around the lake. Amy and I also enjoy riding bikes from Redmond to Redhook on the Sammamish river trail, a pleasant 10 mile round trip. (Admittedly, this is just a thin excuse to eat out and have beer for lunch on a day which isn’t going to be sunny in the mountains.)

Bike Commuting:

Riding to work on a sunny day and taking fun rides on the weekend are a lot of fun and a nice way to get some exercise, but they hardly count as bike commuting. Bike commuting is something altogether different. Bike commuting is riding to work when it is cold, raining and dark outside. Needless to say, Seattle has an abundance of these days, and an abundance of Bike Commuters. Let’s explore what bike commuting is all about.

Today was my first day as a Bike commuter.

I got up, put my climbing gear and bike lock in one pannier, a change of clothes for work, shoes and lunch in the other. After the extra few minutes it takes me to put on bike shoes, open the garage, get out the bike and close and lock the garage, I’m on my way riding up the hill. The road was wet, but no rain, yet. At about mile 2, I pass Google’s Kirkland campus. (An enviable commute, yes, but why bother ride my bike at all for 2 miles of exercise.) The Internet’s masters of primary colors torment me by turning the rain back on just in time for my hill climb up 68th/70th street. Now I’m glad I have my gloves on, but I’m staying pretty warm with the workout. I’m also noticing those wet leaves don’t have the traction I’d like. Caution sets in.

Once across i405, the ride gets less steep, and after passing the Red Apple, it’s almost all downhill from here. At the next intersection, by the Sixty 01 condo community, I have to decide: muddy and fast, or paved, annoying and steeper. I choose muddy, turning right and taking the Bridle Crest Trail along the side of the Bellevue golf course. Without fenders, the amount of mud thrown up by my wheels on this mostly gravel trail was impressive. Now I’m really wet, even my toes are wet, but i’m just a couple blocks from work. P.S. Thank you Redmond for installing metal access panels on the sidewalk. They are insanely slippery when wet.

After my day of work, I needed to go to REI and buy a headlight for the bike. I saw one there on sale I wanted to try, 150 lumens, charges on a USB port and on sale for around 50$ (from 100$ retail.) Thankfully no rain on my way there or on my way to the climbing gym. Thank you Redmond for generally good bike lanes. (They should be! Their nickname is “Bicycle capital of the northwest”.) After climbing with JK, we agree to get teriyaki at Yummy Teriyaki. As I hop on the bike again, no rain, but it picks up a bit on my way there. I was only a couple minutes slower than he was in his car – win!

Unfortunately, the ride home from Teriyaki was the worst stretch of my day. 1) I ate too much teriyaki – I was hungry from all the climbing and biking. 2) The rain intensified a bit, and it got quite a bit colder. 3) Worst of all, the ride from Redmond to Kirkland is horrible. I could have gone way out of my way, but I really just wanted to get home – so I took the direct route.

Getting through Redmond on Redmond Way was easy. On a flat, I can easily keep up with city traffic, and my front and rear lights made me easy to see. Going up the first section of hill was OK too, since I decided to use the sidewalk. (Probably a no-no for a “Real” bike commuter, but really, who wants to be squished on blind turns by cars going 45 mph.) Next, there is a 1/4 mile section where there is no shoulder and no sidewalk. There is a guardrail, and on the other side a mud and gravel “path” which is 6 inches wide with a significant side slope. Failure isn’t an option, since you would fall down a big muddy hill into a drainage. Thankfully, my bike has fatter tires than a normal road bike since it was built as a cyclocross bike. After that, there is a nice section of generous sidewalk, followed by a motley arrangement of sidewalks, asphault chunks parking lots and gravel to get through Rose Hill. After crossing under 405, iI was back on familiar turf, and had no problem getting home. All said, it wasn’t that cold or miserable, and I did get a good workout in today.

In summary, based on one day of experience, Bike Commuting is all about:

Cold + Wet – If you aren’t suffering, it isn’t bike commuting.
Expensive – All the gear to make it reasonably safe adds up. Rear Light – 25$, Front Light – 100+$, Bright Clothing, Fenders, Panniers, Rack, etc…
Saves Money – Yes, it is expensive, but if I ever pay off the costs of all this extra gear in saved gasoline and maintenance on my car, the savings are not insignificant. (~5$ day saved.)
Dirty – Water and mud flying every which way.
Smelly - By the time you get to work, you are dirty and wet, by the time you need to go home, your wet, dirty biking clothes stink. (Showers at work are a reasonable mitigation.)
Slow – When you are tired and keep hitting snooze, bike commuting isn’t going to help you make that 9am meeting.
Free Exercise + Saves time – No gym membership required, plus you can fit a 30 minute exercise in the 15 extra minutes it takes to ride the bike instead of drive.
Eat more food – I love food, and I can eat whatever I want for lunch on the days I ride my bike. (I feel like my metabolism is raised all day with just two 30 minute rides.)
Self-righteousness – When it comes down to it, after riding your bike to work on a crappy day, you just feel better than everyone else. (Look at all those lazy slobs in their cars!) I’m pretty sure this is the primary motivation for most Bike Commuters, since the rest of the rest of the strengths and weaknesses barely balance out.

Disclaimer: While it would no doubt be useful to my (limited number of) readers to post a follow-up in a few months with tips and tricks, favorite commuting gear and an update on my progress, this is unlikely. As evidenced by my sporadic blog postings, there is no guarantee that I will ever post a follow-up to today’s post on Bike Commuting. I can’t tell you what my next post will be about, but it will most certainly not be about the ancient art of Bonsai Kittens.

Major Update to the National Park Service Checklist app

August 10th, 2011 by Tom Alphin No comments »

I’ve completed a major update to my National Park Service Checklist application, adding the ability to view and record your visit to all of the sites in the National Park Service. This includes the many National Monuments, Historic Parks/Sites, Battlefields, Recreation areas and more… nearly 400 sites!

I’ve also taken the time to introduce a new home screen, leveraging the horizontally scrolling “Panorama” control which are a core design pattern for the Windows Phone. This makes it easy for users to see just those sites of a specific designation (ex: monuments) or region. I show your progress against each of these areas, so you can see how close you are to visiting just the 58 national parks, or visiting every site in the National Capital Region.

As always, this is a free upgrade for existing customers. I have kept the price low as an introductory offer, just 1.99$, although this may change as I have added so many new features in this update.

Download this app: If you have Zune app installed on this PC, or are viewing this page on your Windows Phone, visit http://windowsphone.com/s?appid=358c0575-ad86-e011-986b-78e7d1fa76f8 for a free trial, or to purchase this app.

Version 2.0 adds:

All of the sites in the National Park Service, totaling 385 sites. (395 if you count park + preserve twice as the park service does.)
A bold new home page with photos for the most common designations, plus a page to view sites by region w/ an region overview map.
Dynamic “places” view to show all of the sites of a specific designation or region, plus progress (28/58 visited) and brief description of purpose of designation.
Progress indicator when loading the app and when viewing every park of a type or in a region.
A short description about each park service designation to help visitors understand how they differ. (Ex: historic park vs. site)\
Moved “learn more about the NPS” to a separate page to simply home screen.
Updated icons and loading screen.
(Trial mode is limited to viewing the 58 national parks, and recording your first three visits.)

P.S. This weekend we visited Channel Islands National Park, camping for one night at Scorpion Harbor on Santa Cruz island. We had a beautiful day hiking to Smugglers Cove, and the next day we hiked out to Potato Harbor before catching our boat back to the mainland. This trip, plus our July visit to Cuyahoga Valley brings me to 28 of the 58 National Parks (I’m almost halfway there, although we’re only visited 13 parks together.)

Introducing the ‘National Park Checklist’ app for the Windows Phone 7 platform

May 30th, 2011 by Tom Alphin 10 comments »

I’m pleased to announce my second app for the Windows Phone 7 platform. The application follows in the footsteps of Fifty States app, offering a crafted application experience for tracking your visits to the 58 US National Parks. As you may have seen in my earlier post about creating a National Park Checklist wall poster, I have incredible appreciation and passion for these protected lands which have been set aside due to their unique natural and cultural beauty. I’ve created this app to help you engage with the parks more fully, track the places you’ve been, and inspire your next adventures.

Home Screen showing the parks you have visited. (Photo of Capitol Reef taken by me.)

New features in the ‘National Park Checklist’ app.

The National Park Checklist application was built using my Fifty States app as a starting point. Since that application’s initial version 1.0 release, I have made many updates which set the stage for me to create a similar application for the National Parks. In both apps, I now read the state/park data from an XML file, which makes it easier to do the initial data entry and to make updates should I want to add additional capabilities which require more data fields, or to simply fix a mistake in the data. Along the same lines, I am now saving/reading user data to a defined XML schema instead of relying on the IsolatedStorageSettings API. This allowed me to introduce a feature to “back up” your visits data. I plan to introduce an option to restore the data soon

I am particularly pleased with the visual styling I was able to achieve with the National Parks app. I definitely drew inspiration from the National Park Unigrid System that is used in official park literature. It relies on a bold black heading with white text on all materials, and aligning content to strict grids to ensure readability and consistency on literature which is folded. I’ve incorporated photographs (taken by me and my wife) of many national parks. which provide a random heading for the home page, and provide context when looking at a specific park such as Haleakala (see below.) I hope to get additional images for the remaining parks.

I also color-coded the National Parks by region to give users a way to break the insurmountable goal of visiting 58 disparate parks into more achievable goals. The color coding was carefully selected to match the coloring used in the ‘Passport to your National Parks’ program. I have owned a National Park Passport since ’92 and nearly filled several sections during several family road trips starting in ’93. The program is a great way to motivate people to visit the parks and have a stronger connection with each visit.

Fifty States, my first Windows Phone 7 app

February 12th, 2011 by Tom Alphin 6 comments »

Many folks set aspirational goals such as visiting every continent, climbing every mountain over a certain height or running your first marathon. A common goal of many Americans is to visit all 50 US States.

My first app…

I am proud to announce the availability of my first application, “Fifty States”. It is a simple application to keep track of how many of the 50 US States you have visited. I designed the application so you can record more than one visit to each state, along with the date and a short note about your visit. It’s simple, but the app does one thing and I believe that it does it well.

List of the Fifty US States with a count of the number of states visited.

Provide a date and short note for each visit

A learning experience…

While I work in the software industry, programming is not part of my daily job. This was my first time programming in Silverlight, or C#. There was definitely a learning curve, but I was able to create my app in the evenings over just two weeks. I started with the code samples in the SDK (Databound & Pivot were most instructive), leveraged online tutorials (31 days of Windows Phone 7) and asked questions on the developer community at http://create.msdn.com. With all that I have learned, it would take a quarter of the time to do it again from scratch.

One of my goals was to create an application which could leverage one of the unique features of the Windows Phone 7 platform, the ability of the app developer to offer a single installable package that contains both the trial mode functionality and the paid application. This is much easier for developers, as they do not need to create both a free version of their application and a separate premium paid application. Windows Phone developers are free to decide how they want to limit the trial version. Game developers might choose to only offer the first 5 levels, app developers might include advertising in the trial version or offer premium capabilites to paying customers. I finally settled on my own trial behavior, which allows users to use all of the capabilities of the app for free, but limit them to record their first 10 visits to any combination of states. I settled on the lowest price of $0.99, the app has a limited number of features at this time. The Marketplace is flexible enough that developers can change prices at any time, for example I could raise the price due to additional features, but customers who purchase the application now would get free updates.

I also made a nice icon for my application. I wanted to create something which respects the stark iconography and bold colors of the Windows Phone 7 design guidelines, but I also wanted to create something that stands out on it’s own. I settled with a custom white icon on a background of a red leather-bound book, to evoke the exterior of a high-end journal or travel guide. I’m not sure if it works well or is too bold, but I welcome your thoughts.

I picked this project as it was something I thought I could do well and there was nothing quite like it available on the Marketplace. I initially planned to simply create a checklist app with a single checkbox for each state, but that didn’t reflect the reality of travel, that you may visit one state many times before you visit your last state for the first time. I am proud of my app, but also welcome your feedback, any bugs you encounter, or any features ideas I should consider. Please leave a comment on this blog with your thoughts. I hope you like it!

Try it now…

A Gaggle of Geese, a Tangle of Technology…

January 9th, 2011 by Tom Alphin No comments »

I love to travel, and I get a lot of pleasure out of having the right tools to enjoy my trip, and to document the trip in a variety of ways. This Christmas, we went to New Zealand, and we wanted to bring our cameras, a phone, mp3 player, Netbook, and a GPS, but we ended up with a heavy tangled mess of adapters, wires, chargers and batteries. I stuffed it all in a mesh bag to make sure I didn’t lose anything.

What went wrong in the Electronics industry to leave me in this situation, what can I do better next time, and will this ever get any better in the future?

Products, accessories, cables and Adapters required to travel with Technology.

The devices, accessories, chargers, cables and adapters we brought on our trip. (cameras & lenses excluded.)

What to bring?

Part of my problem is that each of the technology items I travel with are excellent at a single thing, so I end up carrying many single-use items like a dedicated GPS or a standalone MP3 Player. What follows is a breakdown of the items I brought with me on our two-week holiday trip to New Zealand, and an assessment of how everything worked out and how I might do it better next time.

Cameras: This includes the cameras themselves, and a small collection of lenses we share between two cameras. For this trip, we brought 4 lenses for our Canon Cameras: Canon EF-S 10-22mm F3.5-5.6 Wide Angle Zoom Lens, Sigma EF 30mm F1.4 Midrange Prime Lens, Canon EF 100mm F2.8 Prime Macro Lens, Canon EF 70-200mm F4L Telephoto Zoom Lens. (The majority of our photos were taken with the 30mm Prime which is excellent and sharp, and the 10-22mm Wide which continues to be soft and disappointing.)

Beyond the Cameras and Lenses, we brought enough memory cards such that we did not need to download and reuse them on the trip. (A total of 128gb in SD Cards of capacities ranging from 4-32gb stored in a sturdy Pelican case). This was more than enough storage, especially due to poor weather which limited our shooting. We also brought a spare battery for both cameras, and the charger for each camera since they are slightly different. We also carried a lens cleaning pen, and a Mini USB cable to download photos at night.

Geotagging: Beyond the photos themselves, I enjoy GeoTagging almost all of my photos. This associates an exact location with each photo, allowing you to see where each photo was taken on a map. Since very few cameras actually include a GPS unit, the main way to do this is to carry a handheld GPS unit wherever you go which records your location every few seconds as digital breadcrumbs, called a Tracklog. Later, a software program on the computer can compare the timestamp of each photo you took that day to the Tracklog to determine exactly where the photo was taken. This works best with a high-precision GPS that has excellent battery life. In my case, I use the Garmin GPSMAP 62s, which is extremely accurate, reasonably lightweight and also has the ability to show detailed topographic maps of your current location. I made sure to download the high resolution Topo Maps for all of New Zealand before we left home, which prevented us from having to buy costly maps in preparation for our hikes.

Ofcourse, another device means additional accessories. The Garmin GPS uses standard AA Batteries, which would be great, except I needed two batteries per day. To achieve this knowing that we wouldn’t be able to charge them every night, I needed 6 batteries in total and a compact charger. I use the excellent Sanyo Eneloop rechargeables to save money and I found an Eneloop-branded charger on Amazon that charges two batteries in 6 hours from a USB port.

Auto GPS: Beyond the Handheld GPS which recorded tracklogs and went with us on hikes and walking around town, we brought a dedicated Automotive GPS with “Routable” maps of New Zealand. We learned travelling in the UK and Ireland that a GPS can save incredible amounts of time and frustration fiddling with maps and trying to keep track of where you are and where you are going. We continue to use a 3 year old model, the Garmin Nuvi 200 because it still works fine and accepts current maps for all over the world.

It includes a suction cup mount to attach it to the window and as expected, it requires a proprietary car charger that plugs into a serial port. It is particularly bulky, and frustrating as the device uses a USB port, but refuses to charge with anything other than the special charger.

Phone & Entertainment: Another set of gear came with us to help pass the time and serve other roles. We each brought an MP3 player to help with the long flights and provide variety while driving. I brought my unlocked iPhone so we could buy a SIM card if we liked to make reasonably priced calls. Amy also brought her Kindle, as it is much more compact than the stack of paperbacks she used to travel with.

All four of these devices charge off of a USB Port, but all but the vintage iPod Shuffle have proprietary connectors. (The iPhone and Zune are inexcusable, but the Kindle should be commended for using the standard Micro USB cable.)

Laptop: To back-up our photos, entertain me on the flight, and watch a couple movies, we brought an Acer netbook computer which is extremely small, and I was able to upgrade it’s hard drive to a whopping 500gb. I put 100′s of movies on the computer before leaving home including a couple of Christmas movies. Even with it’s modest Atom CPU, it was able to play standard definition movies, browse the web or using Google Voice to call our families. Backing up photos was a little sluggish as Adobe Lightroom does not do well on slower machines, and tagging/reviewing photos was almost unbearable. A couple times I tried to develop a photo, but this was too slow to recommend.

The laptop was one of the worst offenders in terms of bulky accessories. The Power Adapter is very large with an unnecessarily long cord, the extended battery gave us 8 hours of battery life but is very bulky and heavy, the mouse is nice to have but additional bulk, since it lacks integrated bluetooth we had a USB Bluetooth adapter, plus a Bluetooth headset and charger to make phone calls.

What happened?

There are a variety of problems at play here. As noted, most small consumer electronics have settled on USB to charge, but at this point, each one uses a different cable to connect on the device end: Kindle uses a MicroUSB connection, iPhone and Zune use a proprietary connectors, my old iPod Shuffle uses the larger standard USB connection. The proprietary connectors are caused by the manufacturer’s desire to sell accessories that would not be practical with only the 4 wires contained in a USB Cable. Accessories and replacement cables are likely profitable! (Even the tiny bluetooth headset charges from the same 5V that the rest of these devices use, although it was sold with a bulky wall adapter which I cut off and soldered to a standard USB Plug. That’s for a later article.)

As for the Cameras, Laptop and Handheld GPS, each has their own story.

It actually makes sense that the Laptop charger is reasonably large. It likely has a large AC/DC converter, and this creates heat which needs to be dissipated. As this laptop is an inexpensive netbook, they sure aren’t motivated to use the smallest or most efficient components, and I’m sure the unnecessarily long cable was inexpensive, and less customers are likely to complain with a cord that is too long than too short. All that I ask is that they use a shorter cable from the wall to the adapter, since this is the heavier and thicker section of cord, or put the plug right on the adapter itself.

Why two cameras from the same manufacturer need a different battery is excusable. My camera added video recording feature which can use a lot of power so they used a larger battery. That said, there is no reason they couldn’t make a taller battery for my camera which uses the same connection to the charger as her older battery. One less charger would be a tremendous savings. Further, I would accept a slow charge over a USB connection. Since both cameras include a USB port, they should offer the ability to trickle-charge the battery overnight when plugged in. This woudl allow me to leave both chargers at home. (I suspect this is not offered due to concerns of overheating the battery, a charging battery leaking inside the camera, or the few additional components they would need to put in the camera to make it work.)

The Handheld GPS is the most forgivable of the bunch. It relies on standard AA batteries. A built-in battery would be a mistake since you cannot replace it while on the trail, and proprietary batteries would be more expensive for customers and would likely still require a separate charger. Again, I think it would be a great feature to allow slow-charging of the AA Batteries when connected to a powered USB source, but this is a little less expected of a niche product than a mainstream product like a camera.

Next Time…

In the long term, we may see the situation improve as the European Union has pressured phone manufacturers to standardize on MicroUSB chargers. (right in the image below) I suspect that this will continue beyond phones to influence all consumer electronics devices (Mp3 players, bluetooth headsets, GPS devices, E-readers) as economies of scale should make it the cheapest charger on the market, or device manufacturers may decide that they don’t need to include a charger if customers already own one. I can’t wait for the day where a single cable can sync and charge all of my devices!

If I can’t have a single cable which works for everything, a smaller step manufacturers can take quickly is to include shorter cables with their devices. Most customers would be happy with a 12″ cable, and I actually got a cable of this length with a recent portable hard drive purchase. I would love to have even shorter 3″ cables for each device, but anything shorter than 2 meters is an improvement!

While I wait for more devices to follow the same standards, I have called out a few changes I can make next time:

Either buy a third camera battery and leave the chargers at home, locate a universal charger for multiple camera battery types, or upgrade one of our cameras such that they use the same battery and charger.
Leave the 4-outlet USB adapter at home. It worked great for charging many devices off a single outlet, but I could just as easily charge them off the many USB ports on the laptop.
Replace the 4-electrical outlet splitter with a much more compact splitter. It is really useful to turn one outlet into two, but creating four is rarely critical.
Upgrade to a slightly larger, more powerful laptop, and leave the second battery at home. The soon to be released Lenovo x120e with a 11″ screen (399$) looks like a great option for less than half the price of the new 11″ Macbook Air. I don’t need a second battery, since in-flight entertainment coupled with sleeping medicine makes a 13 hour flight turn into a movie with dinner, sleep time, then a second movie with breakfast. (When we needed to use the laptop during the trip it was for short bursts of time. We were able to recharge it in a hotel, backpacker or in the car before it was depleted.) P.S. An Included bluetooth adapter would eliminate another dongle.
Consider leaving the MP3 player behind and relying on the phone for music.
Explore using GPS software on a smartphone instead of a dedicated Auto GPS.
Download travel guidebooks for the Kindle (or smartphone) and leave the paper guidebook at home. (If this works well, one of these Moleskine Notebook + E-reader cases would be a great travel setup.)

Overall, I am happy with the equipment we brought and the optimizations we made before we left home. That said, this was a timely opportunity to review what worked well, what didn’t, what we used a lot and what we could have left at home.

It’s Electric! (boogie woogie woogie)

November 15th, 2010 by Tom Alphin No comments »

This month, we got the opportunity to test two of the front-runners of the race to build and sell a mainstream plug-in electric vehicle. Both cars were designed with different tradeoffs in mind, and each is being brought to market with a different strategy. What follows isn’t a formal review, but my take on the cars based on very limited experiences with each vehicle.

Get familiar with this plug as it will charge your next car

Overview & Pricing:

The first car we tried was the Chevy Volt, an expensive (40,280$ – 7,500$ federal credit = 32,780$) 4-seater designed around a smaller battery back with a 40 mile range and a gas generator to extend the range several hundred miles. It has a jellybean-shaped exterior which is very similar to the Prius and a spaceship interior with tons of bells and whistles that remind you at all opportunities that you are driving a “green” car.

Getting under the hood of the Chevy Volt

Today we participated in a test drive of the Nissan Leaf. It is priced starting at a more reasonable 25,280$ (32,780$ before the 7,500$ federal credit). It’s exterior is more “budget hatchback” than “Prius ripoff” but it still features the vertical column of clear plastic on either side of the rear door which has grown to mean green. The interior is more modestly appointed, with an interior that I found more familiar and much less distracting.

The Leaf is a basic-looking small car

The Leaf is the obvious winner as it is 7500$ cheaper. It also may be cheaper to maintain as it has no combustion engine and needs no oil changes. The Leaf relies more on a high-voltage charging station in the home as it takes 20 hours to charge fully on 110 volt, versus 8 hours with the special charger. With the smaller battery, the Volt doesn’t take as long to charge fully.

That said, it is impossible to predict the maintenance costs of a new technology. (Both have comparable warranties on the battery system at around 8 years or 100k miles, which is good to know, but I expect more than 8 years of a car so only time will tell.) On the pricing front, I understand but haven’t confirmed that these cars are exempt from state sales tax, which brings the effective cost of the car as compared to a traditional gasoline car down by another 2-3 thousand dollars.

Design Concepts and Marketing Strategies:

At it’s core, the Chevy Volt is a hybrid car like the Prius, with a slightly larger battery pack and the ability to plug it in to the wall. It was presented cautiously, as a car with no weaknesses and the ability to drive 40 miles a day without using any gas. They felt defensive about this design decision, and didn’t miss an opportunity to remind us that pure electric vehicles have a limited range.

The Leaf was designed from the ground up to be an all-electric vehicle for everyday use. It was presented in today’s demonstration in a direct an unapologetic fashion. They explained that most people can drive around town all day with a range of 100 miles, and if that isn’t enough, rapid charging stations are getting built on highways and at the places you shop. I felt like the clarity of purpose made for a stronger position.

Interior:

Apart from the different power systems, each car took a different approach to the interior and overall driving experience.

I’ll say it up front rather than dancing around the matter: I hated the interior of the Volt. It felt like a spaceship with a shiny white plastic center console with a massive touchscreen dominated with excessively “green” icons and menus. Despite the shiny veneer, the buttons felt cheap with an incredibly annoying interaction design: The physical buttons which surround the touchscreen respond to touch, not clicking. As such you cannot feel your way around the dash to change the station, since merely touching the button will change the station. It was all made worse by the fact that I expect a car with a final cost of over 30k to have a refined, polished and professional build quality, like that in a BMW or other expensive cars. Lastly, the placement of the battery in a column down the middle of the car means that it is strictly a 4-seater. It’s not that it would be comfortable to carry 5 in either car, but the flexibility is nice.

The interior of the Volt was distracting and felt cheap

By contrast, the Leaf’s interior did little to impress or offend me. As a driver of a 12-year old car that has a fairly spartan interior, I am used to a car with fairly basic controls and displays. The dashboard was straightforward with the expected battery gauges, speedometer and a nicely understated indicator of your driving efficiency. The plastic interior detailing felt solid, though lacking in the aesthetic appeal of polished plastic, metal or wood. The included navigation system and touchscreen was straightforward and responsive. It will no doubt feel dated in 10 years, but hopefully by then you won’t need a special map to find a place to plug in your car. Overall, as a car driver and not a car nut, the interior features aligned with my expectations of a car in this price range and appealed to my preference for function before form and features.

The Leaf has a clean and simple interior with less distractions

Conclusion:

Chevy is trying very hard to market the Volt as a Plug-in electric vehicle with no limits, but it felt like they wanted it to be everything to everyone and ended up building a car that isn’t great at anything and costs too much. By contrast, the Leaf is marketed as a convenient 100% electric car for getting around town without a lot of fuss.

I think Nissan is right. We all know what makes an electric car great: cost savings and lessened environmental impact. That’s why they focused their energy on two things: Making a great car that feels like a car first, and explaining how you can fit it’s need to be plugged-in every 100 miles in to your existing lifestyle.
