Yeah, geothermal is crazy expensive. However, I bet... again with some power equipment, and some good old fashioned DIY stubborn "get it done" mentality, you COULD build a basic geothermal unit. Perhaps not enough to take care of the whole house. But, enough to cool a room in the summer. Our winter temps are so low that a heat pump is not recommended UNLESS you have a back up system in place to cover the many cold snaps.
