@wolfe63said What's the physics behind the amplification? Is it explained, even superficially?
I think you get excess energy in the form of gamma rays when you zap I think some Hafnium isotope with low energy x rays. Then the fit hits the shan and it pumps out gamma. Something like that anyway.
I was just thinking if there is 50 or so higher level of energy going out then if we can trap those gamma rays into heat or something we could have a source of energy.
When they say low level of X rays, not sure exactly how much that is. Could it happen with a normal medical X ray machine output? Not sure.
