It would make it more inefficient in its use of fuel. We do, however, have alternators. Also, electric cars can recoup battery energy similarly using Dynamic Breaking.

I am actually thinking about using that extra energy to power something else on the car Link to comment Share on other sites More sharing options...
TonyMcC Posted October 31, 2010 Share Posted October 31, 2010 Thats o.k. but the alternator which is usually belt driven by the engine already does that. One advantage is that electrical power is available all the time the engine is running, even when the car is moving slowly or stationary. 2 Link to comment Share on other sites More sharing options...
