Re: Mixed feelings
Most of that has to do with the factor of needing to run chillers continuously to pump heat from the "cold" side to the "hot" side instead of simply using 'free-cooling' solutions.
DC run continuously, so they produce heat continuously. Unless you suggest that one should simply open the window to provide cooling during winter, some form of air-conditioning will be running to remove that heat from the DC. Instead of throwing that heat in the air, it could be first go through a large tank of water and if there is any residual heat, it be dissipated in the atmosphere.
Warm water can be used for what you see fit.
