There are lots of scammers out there that sell kits to produce “HHO gas” or “Brown’s gas,” and claim that it will make your car run more efficiently by splitting water into hydrogen and oxygen gas that’s burned in the engine, but you actually get less energy from burning the gas than you put into the electrolysis, so if anything it’s putting more strain on your engine.
It might be possible to make a stationary gas generator that uses renewable energy, but then you’d need to find a way to compress and store the gas safely. Batteries are a more efficient way to store energy anyway.
