Two things:Why can't they put alternators on electric cars?
1. The law of conservation of energy. If you're thinking the spinning wheels can accelerate the car while simultaneously charging the batteries, the laws of physics will disagree with you.
2. They actually DO have "alternators" on electric cars. They are the motors that drive the wheels. When you coast or brake, those motors turn into generators and convert that kinetic energy to electrical energy and help charge the batteries.
