I did a double-take at this, and the implications of it became weirder and weirder as I read through it, since although packing 500 compute modules in oil and dropping them in a cellar should indeed generate a fair amount of BTUs, i have to wonder how useful this kind of relatively low-end and resource-constrained compute would be–there are no details on storage or internal connectivity, so only two things come to mind: serverless functions or a ready-made botnet.
I’m sure someone has drafted a commercial model for this, but who is that product for?
On the other hand, we might just have found a use for Pi-based Kubernetes clusters.
