RE: use half as much energy as the average data center
This is a tired old claim and no longer credible. Only the incompetent are now building data centres that lose 50% of their energy in cooling, across most of Europe / North America you can build a data centre which only needs chillers for a couple of hundred hours per year without any innovation.
This 50% claim is like Chevrolet claiming their new car will save 50% on fuel because it is better than a Ford model-T.
On the flipside the sourcing of the energy from geothermal is very smart and should actually be the focus of the PR.
