It is interesting how many old manufacturing sites all over the place have been converted to computer Data Centers in the modern era.
Why?
Because lots of places making, say, gears or castings or hot forgings had to either heat the metal up before forming it or harden the steel after forming (like Al's gears) and they did that in electric ovens. Those ovens got WICKED HOT and they got that way via electricity.
So.... Having that much electric capability in the site in the first place makes it easy to build up an electricity-eating Data Center. One of my old 492-drive storage cabinets ran on 208 volts, 3-phase at a steady-state of about 43 amps and we used a 60-amp wall plug - BIG sucker, half the size of a football. Gimmee POWAH!
