future of cars

thanks to Mike Daisey for the link. The trick? The Tesla Roadster is powered by 6,831 rechargeable lithium-ion batteries -- the same cells that run a laptop computer. Range: 250 miles. Fuel efficiency: 1 to 2 cents per mile. Top speed: more than 130 mph. The first cars will be built at a factory in England and are slated to hit the market next summer. And Tesla Motors, Eberhard's company, is already gearing up for a four-door battery-powered sedan.
