I don’t know how much energy it could store or how the energy would be extracted.
(I was the one that submitted the above about the ring of ions orbiting the charged metal sphere.) The idea is to trap a slightly positively charged plasma trapped between two positive plates inside the sphere in a magnetic field so massive (100 Coulombs of ions orbitting at 10 million m/sec in a one meter radius orbit would create a massive 100 Tesla magnetic field) that there is enough fusion before the positive charge on the central plasma causes it to disperse. But I suppose it could also work in another way in a manner similar to the device you mentioned by suddenly adding lots of neutral atoms to the ring of ions.
