Coming in a bit late to this (apologies for missing HN yesterday), but I'm the product lead for Crusoe Energy's cloud product--we're in an alpha of exactly this :)

We've got Nvidia A100s and A40s racked in data centers on site; ML training, rendering, simulation, etc. are all great applications for this type of data center.

If you're interested in learning more, crusoecloud.com has some info (plus a signup page), and I'm also available at mike at crusoecloud dot com.
