Most common fission reactions today release most of their energy in the form of neutrons. The only way to extract energy from neutrons is heat. But there are fission reactions which release a large portion of their energy in the form protons. And since protons are charged, their energy can be electromagnetically converted directly into electricity, with no need for intermediate process steps.
There’s already at least one company building prototypes like this, Helion, using D+He3 fusion, rather than the more common D+T fusion in other reactortypes like Tokamaks.
Real engineering has a video on Helion: https://www.youtube.com/watch?v=_bDXXWQxK38
Ok, that is a fair point I hadn’t previosuly considered. Though disclaiming a patent doesn’t loose you all legal recourse.
If someone else tries to repatent it, even if it gets approved, you can still file a challenge against the new patent with the PTO. You (or anyone else, really) would also have a virtually guaranteed court win, even if someone got the patent through and tried to enforce it. All you’d have to prove in court is that prior art of the invention exists, therefore the patent is invalid and unenforceable, granted or not, so it’s unlikely someone would even bother trying to enforce such a patent. A previous, diclaimed patent, of literally the identical technology being on record is pretty iron clad and unavoidable evidence that the patent isn’t original.
