DEEP WATER PUMPING DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently pump deep water by clean energy not attending with discharge of carbonic acid gas. SOLUTION: A pumping device comprises a long pipe 5 extending to a deep water area A; a suction pump 2 to suck up deep water; a gas pressure actuator 3 driven by a pump; and a hydrogen suction discharge reaction container 15 incorporating a hydrogen absorbing alloy 20 to suck and discharge hydrogen gas to operate the gas pressure actuator 3. Further, a heating medium heating tank 26 using sunlight as a heat source and a heating medium cooling tank 30 using sucking water as a low temperature heat source are utilized for suction and discharge of hydrogen to and from the hydrogen absorbing alloy 20.
