A generator would be similar in energy, but would pulse much more rapidly–500 times a second or so, compared with 6/ hr for the experimental device.

DianaHitech, which was located in NJ, unfortunately went out of business and the device no longer exists. It was never fully built, so I believe the peak current obtained was about 0.9 MA or so. We’ve had several discussions with Dr. Brzosko and the cross arrangement of our device was inspired by his.

By the way, in a generator, some of the electric discharge energy that is not actually absorbed by the plasma can be recaptured by well-designed circuitry, so the energy that needs to be captured from the plasma for break-even is less than 100 kJ.

Thanks for answering, Dr Lerner. Seems to be that my estimate for pulse energy was not that far off. 🙂
How much of the 100kJ discharge energy should actually end up inside the plasmoid at p-B11 fusion ignition conditions to reach break-even?
My guess is that reaching a good enough discharge-to-plasmoid conversion efficiency is actually the main challenge of focus fusion?

Wishing you all the best with your fascinating project…
