Even if this method was adopted the same problems exist of contamination, fatigue and corrosion which necessitates replacement of cells.
The only way to make electric propulsion feasible is in closed-loop systems where the power lies in a rail, either buried or exposed just beneath a thin surface and the magnetic field is alternated as occurs in an ordinary induction motor.
The experiment did make use of the old Van Nuys G.M. Firebird/Camaro plant facility for awhile - now it will once again revert to the "rulers-of-the-night."
No way. The true cost of each vehicle, disregarding development cost, was well over $100,000. I've heard estimates at anywhere from $100,000 to $300,000 so I'll be conservative and pick the low one. They were sold at a loss with the profits from gas vehicles subsidizing the price because the government was strongarming GM into producing them. No one who isn't certifiably crazy or a total fool would pay this kind of money for a vehicle that can 1. Under the best of conditions only go about 70 miles before it needs a several hour recharge and 2. needs a brand new $20,000 battery every 2.5 years. and 3. will only go about 30 miles in cold weather before it needs a recharge.
