Needs a running stream but I think it could be adapted for a river, ocean tide, or rain if you re-engineer it.

I wonder if the energy would be greater if you had these a mile apart, for example at a long water dam you have one of these on each end of the dam. It seems the potential energy would pull through the entire lake rather than separated by just 2 feet of pipe.

Check this other video where you can see the effect up close. This technology is how the Nazis created anti gravity craft. https://www.brighteon.com/bc9c88ed-ab5e-43a7-9c88-f6569c50b2b1
