REM@MIT-MC suggested using free electrons from a negatively charged electrode and free protons from a positively charged electrode to make hydrogen for a space city. Sorry - you don't understand the physics of the situation. A positively charged electrode has less than its normal complement of electrons. It doesn't have free protons. Hadrons don't pull the kind of stunts that leptons do about wandering around. In essence you are suggesting using a simple battery to induce fission of low-atomic-weight elements. Far more energy than that is necessary.... Steve Den Beste
