If everybody had a water powered car we could heal the ozone. But too bad we don't. Anyways they actually have them now but there like really expensive. The way these cars work is by splitting the hydrogen and oxygen cells by creating electrolysis. That replaces gas with water. For many years people believed that this wasnt possible, but recently they have created a car that can do it. Its not very efficient though. They are still trying to perfect it.
do watered powered cars work? YES (:
are they reliable?NO ):
