JR: There have been plenty of reactions at 10 to 100 W, ~40 times less. Surely, if they can detect gamma from 4 kW they could also detect them from 0.1 kW. 100 watts continuous and no signal? Where and when? At 100 watts there "should be" a strong detectable signal with the V&B setup, which is superb. Maybe not detectable with a gamma-scout ;) Can you give specifics of the 100 watt deuterium reaction which did NOT show any gammas with a sophisticated instrument? That would certainly change my opinion on this particular point, but let's defer to anyone who can add an expert opinion and this would be worth posing to V&B. I think it is an important point because 100 watts is getting up there. For instance 200 watts into a Farnsworth Fusor will peg any and every meter. I am certain of that. A Fusor with only hydrogen instead of deuterium gives you zero BTW - which is essentially my point. Hydrogen is not active but deuterium is. When helium is the main ash, and when the strong gamma signature is absent at ~24 MeV (invoking some kind of phonon explanation) then we have essentially an alpha emission, and easily shielded. Therefore, you have to look for the secondary reactions - the bremsstrahlung (braking radiation) which would be way lower in energy. If you did not provide a good instrument for that, then you might miss it at 10 watts but at 100 watts it should show up IMO. If anyone out there knows differently - please speak up. Much of the bremsstrahlung would be below the 200 keV level but these have a long Boltzmann's tail. Therefore, at 100 watts into a Deuterium setup - IMO, there should be a strong signal when a high quality gamma setup is provided. Jones
