MIT has come up with an energy conserving device for vehicles. They have turned the shock absorber into a hydralic pump to power a turbine and use it to generate electricity to power the electrical system of the vehicle instead of the alternator. Seems about 1000 watts is available on the typical SUV size vehicle just from the bumps in the road. Big trucks would generate more power to drive cooling systems etc.
The idea is not new . . . 6/13/06
