very clever but I wonder what kind of workloads are being run on these remote/edge compute nodes. there isn't any homogeneity in the network - everyone is going to be on a different kind of network with a huge variations in bandwidth and latency.
can't find any specs on what kind of compute power each physical installation would provide
The compute rig would need to be the size of the water tank to make the business even.
Maintenance cost would be much higher too. Better to keep all compute in house sized DC units and just sell hot water to neighbors.
These guys [1] used to be called Nerdalize and iirc their first iteration looked a lot like this. I think they have since moved to a model of a few select locations where nodes are closer to each other.
