In fact, there is no excess energy or coming out of nowhere, energy is present initially in the form of 30bar of injected and stored gas then 20bar for operation, I repeat that the adiabatic properties of nitrogen, the fact that there is no gas leak therefore 100% tightness plus the fact that all the cylinders and the ducts are polymirror 600 allows this no loss of 'energy,
It's more of a "no loss of energy " than vacuum energy or other
these sentences show a misunderstanding of the scientific nature of energy !!
If at the output we recover 9KW of energy, it cannot be stored for a long time in nitrogen at 30bars, like a gas engine on a tank !!
These sentences copied on the demonstration do not inspire confidence.
Finally, without a ball bearing, the seal will not be better, or even worse, given the necessary spaces too, and therefore we do not understand.
None of these phrases inspire confidence.
Rigorous scientific method with detailed and consistent study is different from belief.
