Let's say that we have a certain small volume, which produces proton annihilations more or less simultaneously inside e.g. a very large rock. What would be the threshold amount of annihilation which potentially could cause the self-sustaining proton and neutron annihilation/decay chain reaction in that surrounding rock? Or does all the energy from the ignition just go into breaking up the nearby atoms?
Would things be different if the ignition happened inside e.g. a block of solid hydrogen? Or water?
Would this approach work more efficiently? http://www.toebi.com/blog/theory-of-everything-by-illusion/annihilation-ignition-device/
You can't produce ``proton (or neutron) annihilations'' since baryon number is conserved-at least at these energies.
@Stam Based on ToEbi one can produce those annihilations. Actually, I have, at the moment, research project starting up on the matter. At first stage, annihilations are produced with two electron beams.

If you've two *electron* beams, you're starting with electric charge -2, lepton number +2 and baryon number 0. You don't have any protons-so you can call this ``proton (or neutron)annihilation'', but that's because you don't have any to begin with.
@Stam Ou, I expressed myself poorly, sorry about that. This first, starting up, experiment is indeed conducted with electrons and in this case we are aiming at electron annihilations (2 photons). Principle is the same in both cases (proton and electron annihilation).
e + e -> e + e + X
with X neutral from charge conservation. If the total center of mass energy is less than 1 MeV, you don't produce anything beyond photons and neutrinos. If it exceeds 1 MeV, you can produce electron positron pairs, so X = e^+ + e
If it exceeds 2 GeV you can start to produce proton-anti proton pairs or neutron-antineutron pairs. You will always have the two electrons (per collision) of course.
Electrons *cannot* ``annihilate'' electrons, due to charge conservation.
Obviously you will, also, produce *a lot* of photons, since the dominant interaction of electrons is electromagnetism. But to do all that you'll need a lot of energy, since the electrons radiate a lot as they are accelerated.
@Stam Our plan is to use only few eV. The idea is to trigger electron annihilation just by manipulating electron spin and put those (anti-parallel spin) electrons together in certain manner (described in attached paper).
I know that it sounds unbelievable but the model behind the idea is actually verified experimentally, so I consider the positive outcome pretty likely.
You're confusing antimatter with spin polarization. So what you're after is spin flip processes. These, of course, have been widely studied in condensed matter physics.
However you ``put together'' two electrons, though, you'll always have charge -2 for the pair. You can use interactions to change the spin configuration and the angular momentum of the two electrons-but that's it.
@Stam I'm well aware of spin polarization and antimatter in contemporary particle physics terms. Both of them are involved within the experiment, but in a way, which is not yet realized to mainstream particle physicists.
Things obviously change after the experiments are done and results published.
