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.
Hydrogen fuel cells have been a thing since the 60s. I built one as a science project using bits & pieces kindly donated by John Deere researchers. That is, if you are referring to the cells that catalyze H2 and O2 into water and directly generate electricity.
Henderson generator is not related to engines running on water/hydrogen, except as a possible source for power to separate the water to H2 and 02.
If Henderson generators work, just plug them to an electric motor, it's a more efficient transmission of energy than burning H2 and 02 in a combustion engine.
Energy conversion is subject to entropy, thus perpetual motion discussion is relevant. Hiding the power source by talking about "running on water" is carnival level distraction.
