Better Place showed off its robotic battery changer the other day. So fancy, what with the hydraulic scissor lift and the computers and what-not doing the job in less than a minute. Expensive too, at half a mil per.
Our friend Darin Cosgrove over at Ecomodder.com has a much cheaper system for swapping the batteries in his homemade EV. Of course, it isn't quite as high-tech.
Or as fast.
