Abstract:
An energy collecting system, comprising:a heat storage; a heat source for imparting heat to water supplied from the heat storage by electric power from a commercial power source and thereby producing cool or warm water; a primary cool/warm water pump for pumping up the water from the heat storage and supplying the water via a sucking pipe to the heat source; a motor for driving the primary cool/warm water pump; a water supply pipe disposed between a discharge outlet of the primary cool/warm water pump and the heat source; a water supply pipe for returning water from a discharge outlet of the heat source to the heat storage; an expansion tank or a vacuum breaking valve disposed in a highest section of the water supply pipe; a waterwheel disposed in a lowest section of the water supply pipe for collecting potential energy of the water discharged from the heat source; and an electric power generator rotated by torque generated by the waterwheel to generate electric power.
