Your statement that increasing the electrical draw on the alternator doesn't increase the power needed (and fuel needed) to turn it goes beyond stupidity.
If your idiotic statement were true, then you could hook an arbitrarily large electric motor to the alternator and run the car and the alternator both off the electric motor. This is called perpetual motion, and rational people don't believe in it.
OH and don't even both with more of your bs. I'm already broken my rule about arguing reality with drunks, religious wackos, NASA lovers, and other head cases
