I remembered having seen it idea before, but turns out it's a bit older
than I thought. It's probably much older still;

https://www.nytimes.com/2011/11/27/business/data-furnaces-could-bring-heat-to-homes.html

And a company that does it; https://www.leaf.cloud/truly_green

Still wondering about the security concerns of it, and what of tasks would
be most suitable for it.
