I remember seeing a video in which a heat pump was used to extract heat from the environment and then sent that heat to a boiler. I remember that it was said that the refrigerant boiled at -20 degree Fahrenheit. In the boiler was a refrigerant and the pressure from that boiling refrigerant was used to turn some sort of hydraulic motor. The whole contraption was able to pump water to a higher level (up to a condenser) and also generate some electricity.
Why couldn't that be done on a larger scale?
