PROBLEM TO BE SOLVED: To generate energy by discharging or charging water in a water tank to lift up or down float in the water tank. ;SOLUTION: An external tank 2 for discharging or charging water in a water tank 1 is arranged so as to be easily operated, the external tank 2 is lowered down to charge water in the water tank 1 and at its lower limit the water tank 1 is emptied and the external tank 2 is filled with water to the full, a weight and a float are dropped from an upper space in the water tank 1 to generate energy, simultaneously its own weight is lifted up, the external tank 2 is lifted up using the weight to fill the water tank 1 with water to the full, the float submerged on the tank's bottom is lifted up with buoyancy to generate energy, and the external tank 2 is lowered down due to weight of weights N1, N2 attached to the external tank to charge water in the water tank 1 into the external tank 2 and at its lower limit the external tank 2 is filled with water and the water tank 1 is emptied. This operation is repeated, a variable weight is attached to the external tank 2 so that the external tank 2 discharges water upward and charges water downward, and water weight in the external tank 2 is offset to zero.;COPYRIGHT: (C)1999,JPO
