"BTCS Preparing for Spondoolies SP50 Deployment"

"Ready to accept SP50's, I assume they should be off the assembly line."

Well that answers some of our questions: SP50s are actively being produced, the pictures weren't renderings, queue up now for hash rate.
I just see a bunch of empty racks and transformers. Who knows if they are anywhere near close to production.

you dont drop several hundred thousand (maybe a million+?) on racks, cooling, and transformers unless you have a near-term plan to use them (and BTCS=SP-Tech, so be sure they are gonna be the first)

thats what they have in the second hall, 225kVa (208V i presume) UPS systems. Point me to any other mining facility (besides  legit datacenters/colocations) that use these to prevent electrical downtime

okay after a bit of extra searching it seems emerson offers both 225KVA UPS and 225KVA PDU. I was a bit hasty in my googling, but i imagine this is the *correct* PDU:

It offers the benefits of acting as a transformer, fuse panel, and PDU all within a single unit. fewer cables and devices, better efficiency, and no battery.

that said, having a UPS (or even a capacitor-based backup) would be useful in areas where theres a risk of power fluctuations or 'blips' that could otherwise disrupt operations or cause reboots in the miners. The number of times ive corrupted SD cards in an RPi due to a 'flicker' (even in an office building) is insane, and some devices cant handle fluctuations very well
