Kampfwagen I realize that Fusion reaction produces water as a byproduct said:When did hydrogen fusing give u water?
It gives u helium. Think about it,
D + T = He + n
That is wat the world is trying to solve right now. I thinkl u have got it mixed with with a chemical reaction, the oxidation of Hydrogen which gives u water as the waste. Or u may be talking the long term fusion process, where He fuses with He and form C, N and O. But that is too far away from our technology yet.
