How Do You Cool a Building Full of AI?

AI may live in the cloud, but its heat has to go somewhere. Follow the heat from an AI chip through cold plates, pipes and cooling systems to the outside world. Along the way, discover why denser racks change the problem, why liquid cooling does not always mean consuming fresh water, and what happens when a pump stops. Subject: Tomorrow explores emerging technology, hidden systems and the futures they could create.
