Of course, fusion with elements hevier than Iron (26) does not release energy, but absorbs it. Both nickel and copper are heavier than iron, so the process looks impossible on its face if relying on fusion.
A key excerpt from Dr. Levi:
Together they ran the unit for 18 hours.
“It was extremely interesting. It is clear that this was an internal test that I needed to understand what parameters must be under control during a longer test, but frankly, I wanted to see the device work for hours,” Levi told Ny Teknik
“It was pretty impressive in some respects. First, the repeatability. This is the third time I’ve seen the device, and again it produces energy.”
“The second thing is that this time we loaded the unit with hydrogen at the beginning, and then the bottle was closed. It then worked for 18 hours with the bottle closed. Quite impressive.”
“I weighed container before and after charging, and including the gas we let out to empty the tube of air, the consumption of hydrogen was 0.4 grams. That’s nothing!”
“Minimum power was 15 kilowatts, and that’s a conservative value. I calculated it several times. At night we did a measurement and the device then worked very stable and produced 20 kilowatts.”
“Now that I have seen the device work for so many hours, in my view all chemical energy sources are excluded,” said Giuseppe Levi.
