Don and Steve very good points, Heat recovery and sustainablity is our focus since I founded Cloud&Heat in 2011. We have 19 locations with servers with heat recovery, most of them for heating purposes of adjacent buildings. The original idea was that this makes particular sense for decentralized edge data centers in urban areas and cities.
We found that the key is to achive high temperatures in water of 60°C (140F) and beyond to get the transistion from waste head to a valuable resource. This requires quite careful heat exchanger design and flow rate control. However we also found that the optimum temperature for chips and CPU largly varies on the internal structure and semiconductor properties like leakage current vs. low voltage operation. One of our anchor projects is a datacenter in the heart of the financial district of the city of Frankfurt. We completely refurbished the former European Central Bank data center into a complete water cooled data center providing warm water to the skyscraper heating infrastructure.
