摘要： PURPOSE: To convert energy into electric power simply at a low cost by furnishing a circulation line equipped with a plurality of valves and pumps, locating the line as leading from a pressure tank to a plurality of cylinders, and circulating the water through utilization of the difference in the gravitation of the water and the difference in the water head pressure. CONSTITUTION: The water is circulated through utilization of the difference in the gravitation of the water and the difference in the Water head pressure. That is, the first pressure valve 2 is closed and the second 3 is opened, while the first circulating valve 4 is opened, and the second circulating valve 5 is closed. The weight of a pressure tank 1 and the water head pressure are sent to the second cylinder 13 via the second pressure valve 3, and a piston 14 is pushed to the left. The pressure on the opposite side to the piston 14 should be the sum obtained by adding the gravitation of the first circulation line 6 and the water head pressure to the gravitation of a rising line 16 and the water head pressure. At this time, the water of the first cylinder 12 is lifted to the first upper tank 8 via the first circulation line 6 and returned to the pressure tank 1 by the first circulating pump 10.
