Given that I live on a boat I have often thought of hydrogen power. Breaking down water into HHO and burning that in a boiler to produce steam. The steam would then drive a Tesla disc turbine, which would then drive a generator producing the electricity I want.
Combining the known methods of breaking down sea water, electrolyses, microwave, sound, and so on, should produce far more gas than I would need to fire the boiler.
Just my thoughts on how I might power this boat I live on. It's a 50 foot self powered barge type boat.
Thats just a thought, , ,
