FLOATING BODY POWER GENERATION UTILIZING MICROWAVES UNDER WATER BY UTILIZING MAGNETIC ACTION USING ENERGY OF BUOYANCY AND TEMPERATURE SENSING EFFECT BY MAGNETISM

摘要

PROBLEM TO BE SOLVED: To efficiently convert rotation energy by buoyancy into power generation energy.;SOLUTION: To quickly perform extinguishment and revival of magnetism to be features of a Curie temperature of a temperature sensing magnetic body installed on a maximum outer peripheral surface of a floating body, magnetism is extinguished by being irradiated with microwaves and is revived by being cooled by liquid for maintaining the floating body. When the extinguishment and revival of the temperature sensing magnetic body are repeated, a structure for rotating the whole of the floating body can be made by magnetic stress with permanent magnets. Energy by rotation of the floating body is obtained as power generation energy. By instantaneously heating and cooling the temperature sensing magnetic body under water, the permanent magnets installed at fixed intervals at the outside of the magnetic body and magnetic stress smoothly work to enable a continuous rotary motion of the whole of the floating body. Microwaves can be guided in the water by a wave guide, diffusion of the microwaves can be prevented by an electromagnetic lens, and high temperature heating of the magnetic body can be instantaneously obtained in liquid.;COPYRIGHT: (C)2004,JPO
