See the links below. One is an interview with inventor Bob Albertson. The other is a link to Bob Albertson's website about his trans-electric vehicle.
Bob Albertson has been hired by UAW to convert a gas fueled truck to a totally electric vehicle.
His electric car will have a range of 300 miles on a single 3 hour charge with speeds up to 100 mph and sell for around $30k.
One thing he said is that GM developed a lithium battery (in ?2000) and had a few cars on the road. GM recalled all the cars and crushed them, and then sold the technology to Chevron. A few years later when GM wanted to buy a lithium battery from Chevron, Chevron refused to sell GM the battery unless the car also used fuel.
