A better way to recharge electric cars?

Shai Agassi, profiled in yesterday's New York Times, hopes to eliminate the need for slow recharging of electric cars and jump-start the electric car industry:

Unlike most electric-car technologies, which generally require you to plug your car into a power source and recharge an onboard battery for hours, the Better Place robot is designed to reach under the chassis of an electric car, pluck its battery out and replace it with a new one, much the same way you’d put new batteries in a child’s toy.

Agassi told me previously that his goal was five minutes or less for the whole process. “If we can’t do this in less time than it takes to fill your gasoline tank,” he said, “we don’t have a company.”
