The recent explosion in energy-intensive artificial intelligence projects presents (many) problems, including how to keep them cool. The data centers needed to run them produce massive amounts of heat, and require substantial A/C systems to maintain them at functional temperatures. Vapor compression refrigeration--the method still most often found in cars, buildings, and factories--is commonly used to meet these cooling demands. But vapor compression still frequently relies on environmentally harmful chemical refrigerants. While there are a number of promising, recent advancements in refrigeration, thermogalvanic cells have not really been seriously considered.
