The problem isn't GPUs the problem is cooling them.
Look into what percentage of the ISS by weight is radiators, look into how little power it can generate and radiate, and you'll see that space data centers is the shitcoin pitch of 2026.
- kingleopold 5mo agoAlso they are not building them in 3D space with current tech. We clearly don't have it. Cars barely drive themselves in cities, they are decade behind building and maintaining a. datacenter in space.
- ericd 5mo agoISS is not comparable, we don't have to keep GPUs in human-habitable temp ranges, and radiation speed goes way up with increased temps.
- vkou 5mo agoThe difference in cooling rate between 290K and 370K isn't as large as you think.
- ericd 5mo agoAbout 2.6x? Making a radiator >60% smaller is a pretty big diff.
- vkou 5mo ago60% smaller than 'orders of magnitude way too bloody big to ever make a lick of sense' is still 'orders of magnitude too bloody big'. You know what makes an even bigger difference? Having a planet-sized place to dump all your waste heat into.
