PURPOSE: To obtain rotating power by a method wherein connected tanks of 1 m sq. having gaps of 3mm, for floatation are accommodated in a water tank of 1.005 m sq. having a depth of 100 m capable of being utilized to obtain the buoyancy of the tanks for floatation, through upper and lower pulleys in order to generate a strong elevating power by the buoyancies of the tanks for floating.

CONSTITUTION: The connected tanks 13 of 1 m sq., having gaps of 3mm, are accommodated in the water tank 3 of 1.005 m sq., having a depth of 100 m capable of being utilized to obtain the buoyancy of the tanks 13 by the upper and lower pulleys 2, 5 (5 is a power pulley). The weight of water in the tank is about 1.5 tons and the buoyancy of floating tanks 13 is 100 tons, therefore, the power buoyancy of 98.5 tons may be generated. According to this method, strong elevating stream is generated in the tank to rotate the connected tanks 13 and large power may be generated and transmitted to the power pulley 5. All of electric power is supplied by self-generating electric power and when the amount of water, entering into a tank 10 accompanied with the elevating stream, is decreased, water is supplemented by an auxiliary tank 9, which is supplemented from the tank 4 while the tank 4 is supplemented by a water tank 16 automatically.
