I'm going to recommend this documentary, but not without extensive reservations.
Anthropogenic climate change is not as big a deal as it is made out to be. ICES oceanography journal got caught with biased publishing on acidification from CO2. UN got caught disregarding evidence contrary to their narrative. And much of Al Gore's book & movie was bogus. Ice ages would be far worse for humans than even late Jurassic warmth, and that's not even getting into so-called Ice House Earth.
At least some abductions are alien, though. Meanwhile, these folks are still debating stuff flying around and have no interest talking to the people who don't know each other who all have the same stories about what's going on inside them. There are indeed thousands of classified US patents withheld under secrecy orders, there's a cover up on aliens, and some people connected to the USG (and presumably the contractor industry) have done bad things related to suppression of this subject, but Greer's a new ager who runs psychic contactee events out in the desert, and for years has been trying to raise money for 'free energy' startups. One of Greer's close advisers on the zero point energy subject was Tom Bearden, who bought his PhD from a diploma mill. Ditto with Tom Valone's PhD.
Fission works fine for power generation, and alcohol liquid fuels, including methanol, are already capable of being used on most gasoline cars' engines with the right software settings that are conveniently usually deactivated. If you try to activate it on cars yourself, you can be cited by the EPA for "tampering with an emissions control system" even though the car can be run cleaner-burning and more cheaply per mile.
I also came across info years ago on a Canadian gov site that MAJI stands for Major Agency for Joint Intelligence, and I presume is an accompanying organization to the FVEY alliance dating back to the end of WWII that came from the UKUSA & ANZUS agreements. Regarding SEA SPRAY Ops, assuming they're not talking about an unrelated pathogen experiment done in San Fransisco bay decades previously, SEASPRAY was the predecessor of 160th SOAR back when it was dipped into the CIA. What's MAJ Ops? I have no idea, but they've got no proof it's related to MJ-12. NRO & CSS are listed as one joint organization, when it's actually NSA/CSS, though you do see CSS work with the NRO using uniformed USAF at places like Delta 20 in Colorado managing the satellites ULA puts into orbit. Both Dreamland and Groom Lake are listed separately on that document, which leads me to think it might be a fake.
Are some of Greer's more extreme allegations possible? I'll concede, but the USG also has a horrible tendency to overclassify even benign subjects and ideas that don't even work. Are you going to tell me Russia and China, though, are suppressing 'free energy', too? They have plenty of very smart people. How would you explain that? What, Putin's just a USG mole? What's stopping you from secretly selling your 'free energy' back to the utility like people do with excess from solar panels?
Watch it, but realize that Greer continues to make some assertions for which he has no evidence, and he's still in the habit of mixing facts with extreme fantasy. The more you delve into his theories, the more you will find huge leaps.
