I recall there was something about compressed air cars. They recharged via electricity powering an air compressor.

Provlem is, the power output decreases as pressure decreases. This effect is minor in EVs and nonexistent in fossil vehicles. Plus the whole compressed air thing, which is scary.

Nuclear would be dangerous too. The "safest" is a thermoelectric generator powered by heat from isotopic decay. The Soviets used TEGs first for kerosene radios in rural areas and later for nuclear light houses in extremely remote areas. NASA uses them for deep space probes. They don't generate much power though. Maybe a few hundred watts. You'd still need a battery, but maybe you could manage with a lower capacity lead acid battery.

Thank you for the correction. I thought it was maybe the moisture in the air, but hydrogen makes a lot more sense.
