Episode 57 - Precision cooling and political optimism, with David Craig, Iceotope
With AI dramatically driving up density, data center cooling is getting much more interesting.
Iceotope is one of the companies exploring the most efficient and sustainable way to cool down data centers - and their solution is precision cooling. On the face of it, precision cooling resembles immersion cooling - viscous liquid? Check. Bathtub-like container? Check.
But as CEO David Craig explains, it is actually a far more efficient solution. Beyond the world of liquid cooling, we talk about political optimism and how the next generation will hopefully help us all towards a greener world.
