This is the "TROMPE HAMMER" a combination of a WATER RAM and a TROMPE. This device converts water motion into mechanical energy through the water ram effect, then transfers that energy for use in a generator as compressed air. This video shows the construction of the device as well as field use and power generation from the compressed air it produces. I use a homemade Tesla Turbine to produce electric power for my home 24 hours a day.
