IPC: F03G7/10
Filed: 1980-03-06
Abstract: PURPOSE: To obtain infinite power by gravity by a method wherein the leak from between a main body and its cover is pushed by the air pressure up to the dock water through a drain pipe, the main body is always let to float, the right side of the separated main body is let to fall by gravity and these process are repeated.

This leakage is pushed by air pressure up to the surface of the dock water through a drain-pipe 7. The body 1 is always pushed by buoyancy up to the surface of the dock water 5 and on the other hand, the right side of the main body 1 separated by the rubber body 2 drops violently by its own weight. Repetition of this rise and drop turns the main body 1 infinitely, thus, infinite power by gravity can be obtained.
