The principle of work of cavitation heat generators was offered in the early XIX century Austrian inventor Victor Shauberger, who worked in the field of practical hydrodynamics. He created a cavitation rotary-vortex heat generator that worked on the water that heated his housing. In explaining the principles of the operation of the cavitator, the author argued that in its devices, excess energy is based on the occurrence of nuclear reactions. Jameson Griggs offered its design of a rotary heat generator (Fig. 1), which was patented in 1993, entitled “Hydrosonic Pump”. On the surface of a rotor 1 of its “hydrons pump” Griggs has proposed the use of through radial holes and radial depressions 2, which are called “Gryggs cells”.
In our times outstanding Ukrainian scientists and engineers Fominskiy, Posmitniy and other inventors have made a significant contribution towards practical and useful use of cavitation phenomena, creating a number of hydrodynamic rotary heat and steam generators of different power.
