Eventually some guy finds the switch and turns it on.
You should join Hagelstein, Miley, Storms and Sinha. Maybe you could co-publish this with one of them. There are just two minor issues. One, fusion is a strong-force (nuclear binding) phenomenon, not a weak-force phenomenon. Two, we will be able to manipulate the weak force as soon as we have a reliable source of Higgs bosons, if they exist. The LHC is a mult-billion dollar accelerator looking for Higgs as we speak. In the quadrillions of particles they have produced, there is some tantalizing evidence that they might have detected it, or might not have. But if I were you, I would try to publish this theory before someone else does.
