	<htmltext>The probability of digging into any old hillside and create a facility like this is quite low and would be quite expensive.  The reason this exists is due to a (profitable) mining operation in the first place.  So, that should answer your question.  Yes, mining is a profitable business and it is worth the cost to take natural elements out of a mountain.  Once the resources have been harvested simply starting a data center in the space left over would be worth the cost.  Another geological bonus for this location is a nearby underground lake that can be used as for thermal transfer.</htmltext>

Not an insurmountable problem. They should pump heat back into the ground in summer by using the same pipes as the radiator for their A/C. But if they cheap out during installation, the geothermal heat wont be renewable.</p></htmltext>
