Victor Schauberger build various known and unknown vortex based devices that apparently worked just as well as a tornado or a cyclone. And Jim Griggs of Hydrodynamics, Inc. demonstrated the assembly and operation of a "hydrosonic water pump" which operated over-unity by producing hot water or steam with energy in excess of the electrical energy input to the pump motor. So the logical combination of both is a hydrosonic vortex pump. Ideally it would be A self powered pump that heats watter. .
