I'm new to this forum but impressed by some of the expertise apparent in the posts. I'm looking for any examples of an existing geo-exchange system in a dairy. Many reports can be found that identify the opportunities and I have personally worked on some preliminary case studies. Scouring the internet has turned up no results other than some interest at a high-tech dairy lab in Tennessee (MTSU). I help manage an energy grant program that can fund much of the cost of a new GHP system in a Colorado dairy, but it's hard to find someone who wants to be part of the first trial, especially in the highly regulated dairy industry.
