Could you please provide more specifics of what you propose?

Geothermal cooling has been done before but you want to use a water loop to effectively transport the energy.

well, im not a genie mouse when it comes to this stuff, as i said it was just an 'idea'. I would take the air shared from an air-brick with two 160mm fans to create some pressure (under ground floor level) then I would take two runs of piping 80-90mm run it 30-40 cm under my grounding which is only 1.5 meters from the water table and conduit it through an up a thick brick chimney breast where by at the top there would be two out-take fans.. the cooling distance under the ground would be 3.5 meters and the chimney itself would also be very cold. not very scientific but the air should have enough time to get cooled (were not talking freezing air here)

could it work? perhaps i could drop a water tank under there and run the pipe through it ?

Take a look at this diagram:



Using water loop to release the heat to ground. You would have a pump push water up to the 1st floor and up to the fan. The fan would blow the warm air through a radiator. The warm air releases heat to water and pipe. The pipe then goes back down underground and releases heat into the earth. Repeat.

This image shows a coolant and compressor being used as a more complex, yet more effective way of using Geothermal cooling.

I believe that you are right, you never really "cool things down" so much as you get rid of heat.
