If I remember right don't Chevron own some battery technology that they refuse to let anyone use for cars?

Either way, that kind of action is small potatoes compared to the effect of the systematic, ongoing, substantial subsidy for sprawl development.

In the film "Who Killed the Electric Car" they explained how the nice elderly couple who invented the great battery idea for GM was sold by GM to Chevron after they killed the EV1 in California.

Google "cobasys patent".

Cobasys has succesfully sued the major battery-makers of the world. Chevron-Texaco owns half of Cobasys, Energy Conversion Devices owns the other half. They have a very basic patent on NiMH-tech that expires in five years or so. Settlements with major battery-makers expires before that I think.
