5 days agoBe really interested to know what it’s made out of. Had a coworker who used to work in forgings and did some stuff that got sent to nuclear plants, they said that they had really strict requirements on material compositions, specifically needed to ensure that the (think it was steel, may have been something else) material had basically no traces of cobalt in it because the cobalt would becomes radioactive over the service life.
I would be really surprised if anyone is cooling data centres with city water except in emergency, that’s so unbelievably expensive (could see water direct from a lake though but that had it’s own issues too). I recall saving millions just by adjusting a fill target on an evaporative cooling tower so it wouldn’t overfill (levels were really cyclic, targets weren’t tuned for them), and that was only a fraction of what it’d have cost if we’d’ve used pure city.
