55-minutes (the first 4 minutes are ads, last few minutes credits, so about 45-minutes of content)
My TLDW:
He starts by explaining that patents can be seized by the government if they “are important for national security.”
Then he talks about a couple of inventors who invented cars that could run on literal gas vapors, making mileage like 200 miles a gallon (first one was over 100 years ago, I think the second one was sixties?). Then a guy who invented a car that ran on water (early 70s). Then some people who created machines that could generate energy out of the atmosphere, which is basically unlimited free energy (one of them in the 60s).
All these people had their patents seized, labs broken into and all their material stolen and were either financially/professionally ruined or killed (or both).
Interestingly, one guy re-patented all these things with the US military as the owner of the patents, so it appears that the military has stolen these patents and are utilizing these technologies while keeping them from the public.
He goes on to talk about the serious flaws with the current green energy “solutions” being touted.
He shows that there never was an energy shortage, it was a control tool and that the green energy “solutions” are simply measures that will ensure that powerful people stay in power.
I don't now what the OP is referencing, but this ZPE site has been on-line for a long time:

I think this is different technology, being cold fusion. I thought that his device was rejected as fake though a long time ago, but, knowing now how much they want to suppress any sort of free energy technology, perhaps it does work. But if that were the case, I think it would have been all disappeared by now. Note: I have not read any articles on that web site; I am only going from memory of reading about it over ten years ago.
