That link talks about 5MW 35kv AC / 800v DC converters.. completely different thing, they try to sell a single-source PV invertor-to-35KV AC solution first, then 35KV to 800V DC second, to have a sorta complete solution of PV-to-datacenter. And it's only 5MW. And only 35KV AC. For moving 100MW even over a few km you would need 110KV at least. I think. An overhead wire can handle about 600A of current, that's the physical limit and the reason for kilovolts there.
Consider also that there is nothing existing in transmission and switching gear certified for HVDC it being rare one-off projects so far, while AC is ubiquitious, more-or-less mass-produced and many people are trained in its maintenance.
Hm. I think a dedicated 16-core box with 64 ram can be had for under $1000/year.
It being dedicated there are no limits on session lifetime and it'd run 16 those sessions no problem, so the real price should be around ~$70/year for that load.
It looks like, to me, that someone spent a long back-and-forth with an LLM refining a design - everything they wrote screams "over-engineered, lots of moving parts, creating tiny little sub-problems that need to then be solved".
I find it very hard to believe that a human designed their process around a "Daytona Sandbox" (whatever the fuck that is) at 100x markup over simply renting a VPS (a DO droplet is what, $6/m? $5/m?) and either containerising it or using FreeBSD with jails.
I'm looking at their entire design and thinking that, if I needed to do some stuff like this, I'd either go with a FUSE-based design or (more flexible) perform interceptions using LD_PRELOAD to catch exec, spawn, open, etc.
What sort of human engineer comes up with this sort of approach?

I don't know. There is that "just-bash" thing in typescript which they call "a reimplementation of bash that supports cat and cd".
The problem they solve I think is translating one query language (of find and ripgrep) into one of their existing "db". The approach is hilarious of course.
Because where I live around 55th this winter we had five straight weeks below -15c / 5f daily average plus enough snowfall that it was infeasible to clean anything but the most major roads.
Solar is out of question in these conditions and when thermal pump fails you have to evacuate. When just grid electricity fails you have to either have some sort of stored fuel backup or evacuate.
The article is typical handwavy crap which is popular among people living in what amounts to subtropics who can't even imagine how crazy they sound to most everyone else.

To be fair, 90% of the population lives within 45 degrees of the equator. If we're talking about global energy solutions for CO2 reduction, we can go a long way just by focusing on what works in these areas of the globe.
The article does also point out that hydro/wind are going to be important at higher latitudes in winter, but they also acknowledge that they don't account for seasonal variation in demand. That's the biggest flaw I can find in the analysis.
FWIW: I'm down in a mild arid climate at 35N, and yeah, 90% of our winter days are nearly sunny, even when the lows are in the teens. It's a different world for sure.
Most space heating is in the Northern parts though, so those are the ones that need to be addressed. There are solutions that are a pareto improvement, but it's a coordination problem and the USA is sufficiently broken and unable to solve those.
handwavy argument. Yes, in the (sub)tropics the argument is even stronger pro-PV, not the least because it'll give you the opposite of heating - aircon - for free right when you need it. And considering summer heatwaves as have been seen the last few years "way north", that benefit will extend that way even if you wouldn't bother considering letting it "assist", if not fully replace, your heating. That said though, for 50° polewards and above, if you wanted to use PV in winter orient the panels vertically. If you can clad your too floor with shiplap larch so you can with PV panels. Given the price of timber ... there's a plan.

Most everyone else? Only about two percent of the Earths population live above the 55th parallel. There’s a big gulf between that and the ‘subtropics’.
I don’t disagree that solar/battery isn’t the answer for 100% of power needs, let alone 100% of heating needs, but if we got to even 50% we’d be in a lot better situation than we are now.
Evil ballpoint is evil. I remember everyone chewing up plastic ballpoint pens into unusablily and also using them as blowguns with chewed paper, whereas nothing of the sort was possible before their introduction. (however, flowing ink also had its uses :) )
That's how it worked in USSR in 80s. The school supplied the books and they were the ones that the previous grade used. If they got busted beyond all repair only then they'd be replaced with new.
Exactly because no one in his right mind is going to work in "state". So the "state" is more like 95% "fucking idiots" as you put it, and that is self-reinforcing.
It's apparently explicitly supported by dxwnd, but I failed to find anything in release notes or anything like a post you mention. Binary download however contains an 'exports' directory which is basically a list of titles it supports.
Great reading in itself.
