Hmm. Liquid cooling with geothermal heat massing. Bury a long length of
copper pipe at least 10' deep in a cistern of water around 1000 gallons.
Use pumps to cycle the closed-loop antifreeze between the buried water
tank and the insulated heat dump for the liquid-cooled servers. At 10',
the ground stays at the average annual temperature. The water tank is
just for transfer efficiency. It could be done with just buried piping.

Some folks I know have a sizeable pond/lake. They use it for passive
cooling their house. They installed about 100' of flexible poly piping
and use a pump to move it to the house. There it is cycled through a
heat exchanger/blower assembly that looks like a very over-sized AC
evaporator. In August, the outside temp was 99F, the inside temp was
77F. Their average power bill (10 years ago) in summer was ~$40-$50.
