After talking with Brian and Merle last weekend about the mismatch between the short trips and giant cars people drive, I did a little bit of research on current state of electric cars.

The big auto companies have had some small pure electric projects over the years, but lately have focused more on hybrids. This is certainly the most palatable to the consumer, since there’s no change in behavior to get the benefit of greater fuel mileage. Still, the result is disappointing as most hybrids merely use the technology to slightly improve the mileage of big, overpowered vehicles.

A few smaller companies offer more impressive vehicles: Tesla Motors roadster for $90,000 and Phoenix Motorcars pickup for $45,000. Both use lithium ion batteries like those in laptops, which offer a greater range (over 200 miles) and performance for a higher price than standard, heavy lead-acid car batteries. Expensive batteries limit the target markets to rich enthusiasts for Tesla and company fleets for Phoenix, though. Availability is also a year or two away, with a $50,000 Tesla sedan further out according to CNET.

The green crowd has taken matters into its own hands in the meantime; there are many resources for building your own electric car. As an engineer in constant need of projects, it’s certainly tempting. Individual parts or kits can be purchased to convert a gas vehicle at a cost of around $10,000 if you do your own labor. The lead acid batteries will last about 5 years before needing a $2,000 replacement. Older small cars and pickup trucks are favorites, though some sports car conversions have beaten Vipers and other high performance gas racers. Since electric motors have full torque from 0 RPM, they can really launch - another aspect I find personally appealing.

In summary, getting an electric car for today’s common short trips isn’t easy or cheap. The big companies will sell you a hybrid for a premium. A much larger premium gets you a niche vehicle that can be driven off the lot. But to get something more affordable and practical, you have to roll up your sleeves and roll your own.
