I can't see the article- but a little research on ERCOT's wholesale pricing maps reveals two things: 1) today's prices are somewhere between -$200 and +$200 and 2) theres 900+ discrete pricing locales in Texas.

And, here's a bit of reading on the process for a customer requiring >75MW: https://www.dlapiper.com/en-us/insights/publications/2026/03...

Sorry if I find that things like https://pubmed.ncbi.nlm.nih.gov/39804212/ existing in checks 2025 repulsive. Especially when those are the same arguments put forward for lobotomies. If somebody is capable of _ELECTING_ ECT, fine. But don't pretend that dosing somebody unconcious with benzos so they Can't seize, and reducing shock duration and intensity so theres no skin burning makes intentionaly brain damaging somebody to fit in with society any less horifying. If you don't like that example- theres plenty more for things like dementia among the elderly. Especially if they're in a retirement facility.

As for TCMS? It works- if you can find a place that's not a farm.

Because ECT is whitewashed shock therapy, which in turn- is a whitewashed lobotomy.

isn't AVR vs PIC semantics since microchip bought atmel?

Not sure, but typefacing/fonts is absolutely cursed with this stuff. I'd be shocked if there isn't a true type font that runs DOOM. There's a reason Microsoft pushed font rendering out of the kernel in Vista. (Technically, they started the work on it)

it's even worse: SLA's can only discharge to ~half their nameplate capacity or so- and if you're pulling tons of amps, it's even less. LiFePo4 otoh you'll get the nameplate capacity.

Then theres trivialities like LFP's voltage being higher so there's less resistive losses, etc

nothing ever trickled down. philanthropy is not trickle down, and the gates foundation has to be one of the most critical I know of.

I notice nobody- OP/tfa included, is mentioning that that 30ms transfer is 10-20ms longer miliseconds longer than an ATX3.0/3.1 PSU's hold-up time.

LiFePO4 generally has a 0.5 or 1C discharge. You'd end up with a 500W UPS that could run for 10 hours, or 48v+ battery packs.

and yes, they're also happy to heave to: plenty of DC ups' use NMC. Apc can't even be bothered to make a consumer class UPS that works with PFC- at all.

note: its the additional component and its knock on effects that are the cost- not the half cent diode.

aka- you add a diode, now you have to add procurement, warehousing, extra time on the pick and place, possibly a more expensive/larger+slower one as well(so even more time), then you have wastage, labor for keeping the machine fed...

theres also anderson's SB series- APC seems fond of knockoff versions.

I can't imagine theres much overlap between "we will need to update this firmware for the next decade." and "Let's bet the farm on the documentation being perfect, and all the downloads still available."

Same for the US- until the feds broke up Bell between 1974 and 82. but, there were no technical hurdles. Anybody have a toy whistle?
