Look at what London has done to their subways. Geothermal cooling only works so much and eventually your geo becomes a thermal battery saturated with heat and won't take any more.
- saeranv 8y agoExactly, even if you have closed loop geothermal heat pumps (which more efficiently exchanges heat from the thermal mass of the ground and the refrigerant pumped through a heat exchanger) you are still limited in the amount of heat the refrigerant can exhaust into the ground before you've heated up the ground where it's not possible. And vice-versa in winter where you can freeze t he ground solid by doing the opposite. Still a good idea, but has scale issues especially for high-density areas.
