Here is the thread I found this on https://boards.4chan.org/pol/thread/378598168
What a coincidence. This man built a engine that ran on water and he happened to get killed in the Buffalo shooting. Here is proof of his engine https://www.youtube.com/watch?v=SAFQdYYXyls
It's entirely possible this was a conspiracy murder by the oil companies to assassinate the inventor that would make their product obsolete and bankrupt them, disguised as a white supremacist attack. A similar thing happened to Stanley Myer, the feds poisoned him because he made a car run on water.
A few weeks ago I discovered this video https://youtu.be/1xHQWu2ZzPc A man put a lawnmower carburetor on his old car that had a V8 in it and got 45mpg after tuning it. I wonder if the feds will come after this guy too. He has not made a video in weeks.
Still, how much energy to purify aluminum? There is a lot of energy stored in pure aluminum. See: https://en.wikipedia.org/wiki/Aluminium%E2%80%93air_battery
If they could get it to work, it'd be safer than lithium or gallium. But these are battery techniques, not fuel.
"They" can worry about pure aluminum. I would build something that uses aluminum in whatever form I can get my hands on easily.
