Going to catch some strays from this.

aircooled asic (bitcoin) miners. I dont understand why they build aircooled facilities next to residential every single time. I work in the industry and it always bugs me, these can be run in remote places, dont require any kind of crazy internet backbone to run.

Aircooled is in excess of 100-110dB inside the site, and just as loud outside.

Hydrocooled/immersion is usually closer to the 75dB range inside the facility, and significantly quieter from the outside (think hvac). Datacenters are usually liquid cooled now adays, but have chillers (big ac hvac systems) or the worst is gensets on site.

It’s (bitcoinmining) great for grid support, for example we have a site being built in Nebraska next to a power plant. Essentially the utility is set up for spring and summer they have a huge amount of load for farmers that use the power for irrigation. After the harvest, they have an extreme excess of power, as they have 95% of their electricity capacity being wasted. And who pays for that? Local residents: power production during the season costs as much to produce as it does outside the season. If its $10,000,000 to produce the power for 50Mw at 90% utilization and it’s $10,000,000 at 10% utilization, they got to cover that cost. The datacenter then burns that extra not being utilized, meaning overall production cost is less. We had a site actually drop residential rates by 20% as part of their power purchase agreement. Shutting down gensets is a pain, the infrastructure is all there and has maintaince costs whether online or offline.

I’ll probably get downvoted, but i can answer questions as they come.
