Fuelless Water Pump
This is based on a 200-year old French patent.
Allegedly can pump water continuously.
However, the video only shows the amount of water coming out consistent with the amount of air in that pipe would hold. Imagine a Super Soaker getting pumped before filling…that’s similar to what you’re looking at. It’s probably not an OU device. It may just be related to a hydraulic ram type system.
