The FF device isn’t designed to extract useful energy out of these reactions, but it should be able to show theoretical over-unity with these fuels at much lower temperatures than pB11. From a funding/publicity perspective, is there any value in demonstrating over-unity with these fuels before going to pB11, or would those just be distractions?
Since we’re on Goal #6, which includes “heavier gasses”, helium3 may be included, but I doubt it due to all the potential for that rare and expensive fuel to confuse things.
Goal #7 is to demonstrate the pB-11 fusion that FF-1 was designed for, and Goal #8 results from tweaking it until the neutron tof detectors confirm that more energy came out than went in to start the fusion reaction. My guess is that LPP’s going to have some amount of over unity in the bag before announcing unity.
The drift tube’s Rogowski coils would be a nice addition to the diagnostics, but they aren’t absolutely required to demonstrate net theoretical energy.
