Here are some free ideas
To the research scientists trying to understand fusion (instead of building reactors that make electricity).
Here's some free ideas. You're welcome.
1. start acting like this is a problem that needs to be SOLVED, instead of UNDERSTOOD
2. 1 word: RESONANCE [if you're a nuke scientist you know what this means]
3. Study how a 'travelling wave tube' works when it's creating or amplifying microwave frequencies, particularly with respect to "electron bunching" (and RESONANCE). Applications obvious.
4. Consider magnetic lenses and magnetic compression, not a toroid
5. There's an existing design that seeks to eliminate the effects of a torus causing the inside track to be slower than the outside track, something that was once pursued by the U.S. Navy, but somewhat recently abandoned [probably for something a whole lot better that's classified]
6. You're going to have to get energy out of the reaction at some point. Have you figured out how to do this? I suggest making the reaction happen inside a cavity within a large tank of water [aka 'boiler']. Steam systems would then attach to it. the rest is kind of obvious.
7. superconducting magnets lose their magnetism and/or superconducting properties under high doses of gamma radiation. don't use them. Pulsing electromagnets would have other benefits as well. Try those.
8. electrostatic focusing has been used for DECADES with various kinds of vacuum tubes/valves. Resurrect that tech, except using it for protons/deuterons/tritions etc.
9. deuterium and tritium are NOT the only fusion fuels. How about firing high energy protons at a solid lithium target? Or maybe lithium at lithium? Whatever, just try things. Inertial confinement seems to work kinda well with a solid fuel pellet, though it takes too much energy to burn the fuel. How about if that pellet crashes into "other fuel" ?
anyway, just thought I'd mention things like this in a different venue. who knows, it might work.
