If we can use hydrogen to power electric motors, why can’t we use water to run a car? - eviltoast

Can’t you just break down water, use the hydrogen to power the electric motor, and I don’t think O2 as a byproduct is bad, now this is of course an ideal condition, but why hasn’t this been looked into more?

    Water contains two elements, hydrogen (very explosive) and oxygen, which can make almost anything burn. You’d think tossing a match into a body of water would end all life, for the amount of stored Oxygen and Hydrogen. It won’t because it is essentially ash. Inert. It takes a large amount of energy to separate the Oxygen and Hydrogen from each other, before either could be used again. That is the problem. That’s why we don’t pour a gallon of water into a tank and head across country.
