>> [...] When in heating mode, a refrigerant at the warmer temperature is compressed, becoming hot. Its thermal energy can be transferred to the cooler space. After being returned to the warmer space the refrigerant is decompressed — evaporated. It has delivered some of its thermal energy, so returns colder than the environment, and can again take up energy from the air or the ground in the warm space, and repeat the cycle.
Great to see that even Wikipedia struggles with this :-)
This is 100% wrong.
Transferring heat from a warm space to a cold space happens on its own and does not need a heat pump. In the contrary, you can even extract mechanical work from this process.
Heating mode means heating a warm space by transferring heat from a colder space, which requires work.
If you convert all of the local thermal gradient to electricity, there's no work left to do without a pressure gradient in the loop or passive exchange to keep a thermal gradient there?
According to Superfluid Quantum Gravity, black holes and the quantum foam have a gravitational pressure gradient; vortices given density.
