I just saw a thread about "easier" methods of nuclear fusion. I have a concept of my own, but I'm not well enough read on plasma and particle physics to know if it would work. Basically, my idea is nuclear fusion minus the nuclear; instead of fusing hydrogen isotopes, fuse electrons. From what little I understand of the process, each nucleon has a mass roughly 10000 greater than electrons, so would that mean that electrons require less energy to overcome the Coulomb force and fuse them, or would that mean you need an even stronger magnetic field since the strong force and gravity aren't as much in play? The other question that occurs to me is that, given circular particle accelerators of equal energy, electrons will emit more Bremsstrahlung radiation than protons, so does that mean one of the problems with fusion reactors today (the strength of the shielding) would be magnified in any "electron fusion reactor?"
