I understand what your saying.. I said energy meaning electricty rather.. it does take mechanical energy to turn an alternator.. thats why it is hooked to a belt on the engine... hehe...
but i am saying it doesn't require electricty to operate it.. just a turning force. If the front wheels are free spining already.. well theres your turning force just ready to be exploited
for the making of more Electric energy.
blah.. a good conversation though..
