With microfluidic cooling, liquid flows through channels etched onto the back of a chip. The trick is making sure the channels, about the width of a human hair, are deep enough to prevent clogging but not so deep that the chip becomes more likely to break.
Two things here -
- Since the coolant does not need to cool the metal stuck to the chip, it does not need to be as colder. So less energy.
- During spike in demands, you could overclock, instead of scale so less machines, possibly.
Big Tech Dreams of Putting Data Centers in Space by Sophie Hurwitz
Altman has proposed creating a Dyson sphere of data centers around the sun, referring to a hypothetical megastructure built around a star to capture much of its energy. The rather glaring downside to this is that building it would likely require more resources than exist on Earth, and could make the planet uninhabitable. But somewhat more realistic plans are inching closer to reality. Startups like Starcloud, Axiom, and Lonestar Data Systems have raised millions to develop them.
It will be slow though getting data to and from these DCs. Wireless is very slow compared to fibre.
