nice MAN! good idea.

Shouldn't Prot-Prot reactions produce tons of neutrons/electrons/antimatter?

and please tell me if this was talked about in an earlier page, but could you make it so that if PROT touches Hydrogen you get Deuterium

That would make a Helium-4 isotope (in the form of plasma due to there being only one electron in the process), not Deuterium.

Actually, it would make a helium-2 isotope, as hydrogen usually only has one proton, with no neutrons. However, the helium-2 would rapidly decay either by fissioning back into two protons, or it would beta decay into deuterium, emitting a positron in the process.

Sort of like how some isotopes decay into photons?

Although no known isotopes decay purely into photons, photons are emitted in many radioactive decay processes. That said, in the case of helium-2, photons will be generated, not by the decay itself, but from the positrons produced colliding with electrons and annihilating, if the helium decays by positron emission to deuterium. If it takes the more likely alternative path of fissioning into two protons, no photons will be emitted.

Wait, what? We are getting protons! YES! Finally! I haven't been checking this thread recently because I thought it was just a huge flame war going on, but I see that @Jacob1 has been experimenting with them.
