looking for a gas compressor to experiment with hydrogen internal combustion engines, my first piece in putting my generator together. Compression is needed, because fuel cells are too expensive and sensitive, and electrolysis on the move requires too much power. Diesel? IT might be free, but it doesn't solve our energy problem! Any other gear including tanks, gas regulators, hose, high pressure small volume chambers etc. are welcome as well.Thanks! 1000 dollars or less please! I'm still experimenting, and I'm a student!!!
