The high-performance cluster server is submerged in a pool of mineral oil - a very effective way to cool systems - and a heat-exchanger transfers the heat into the children's pool! The pool still has a boiler in case it gets too low, but overall it will save a lot of money.
The company behind the install is trying to create more installations like this to recover waste heat - this pool installation claims to recover 97%(!) of its waste heat - rather than just venting it into the air and causing more climate disruption.
