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?

Electric heaters aren’t 100% efficient, because some of the energy is wasted altering the resistive material chemistry and emitting other electromagnetic radiation, and even sound, that doesn’t heat the air inside your house (right away). Still at a perfect 100% efficiency, it takes 1 joule to raise your house temperature by 1 joule, ideally. Heat pumps, which are just an AC unit running in reverse, are more efficient than electric heaters. Some heat pumps have a coefficient of 3. Meaning they take 1 joule to heat the air in your house by 3 joules. Because they don’t try to heat the air, they move heat to the air from outside, and they can achieve this even if outside is freezing.
That’s the theoretically part - there are processes that will capture the energy generated that would’ve otherwise become heat, but that only affects the timeliness. Given enough time, all workable energy generated by a heater would become heat, even if you had to wait for the matter itself to decay trillions of years from now when all the stars have long since breathed their last breath.
Also has somebody watched Technology Connections by any chance?
Heat pumps are so cool - if you showed onw to someone even a hundred years ago, even knowing what electricity was, they’d think it was magic.
