Semi-related. I think a better solution to this DC problem (and a nice revenue stream for vendors) is to figure out something like this [1][2] at scale. Basically, instead of saying "we're going to subsidize our DC build outs by increasing your energy costs," say "if we can install a small compute node that receives workloads in your house (make it a kit so it's easy), you get the heat for 'free.'"
I'm ignorant to the specifics of how this might work (and whether it'd even be feasible at a cost/logistics level), but it feels far less invasive and far more sustainable as an armchair thought. Curious if anyone has worked on something like this and what sort of gotchas you've found.
