Run the car on hydrogen and release oxygen into the air. We mad an electrolyser in my science class.

Hydrogen is very very flamable. I sure as hell don't want to be driving around in a mini-hindenburg. There would have to be a very very rare electrical current, so there is barely any hydrogen in the motor at once. And it would have to be very safe to be put out on the road.
