You know the jig is up for “renewables” when even Silicon Valley techbros turn against it

JoNova on the remarkably quick change of opinion among the big tech companies on the whole renewable energy question:

Google, Oracle, Microsoft were all raving fans of renewable energy, but all of them have given up trying to reach “net zero” with wind and solar power. In the rush to feed the baby AI gargoyle, instead of lining the streets with wind turbines and battery packs, they’re all suddenly buying, building and talking about nuclear power. For some reason, when running $100 billion dollar data centres, no one seems to want to use random electricity and turn them on and off when the wind stops. Probably because without electricity AI is a dumb rock.

In a sense, AI is a form of energy. The guy with the biggest gigawatts has a head start, and the guy with unreliable generators isn’t in the race.

It’s all turned on a dime. It was only in May that Microsoft was making the “biggest ever renewable energy agreement” in order to power AI and be carbon neutral. Ten minutes later and it’s resurrecting the old Three Mile Island nuclear plant. Lucky Americans don’t blow up their old power plants.

Oracle is building the world’s largest datacentre and wants to power it with three small modular reactors. Amazon Web Services has bought a data centre next to a nuclear plant, and is running job ads for a nuclear engineer. Recently, Alphabet CEO Sundar Pichai, spoke about small modular reactors. The chief of Open AI also happens to chair the boards of two nuclear start-ups.

Gustloff VG1-5 Nazi Last Ditch Rifles

Forgotten Weapons
Published Nov 20, 2015

The Volkssturmgewehr Gustloff, more commonly (albeit incorrectly) known as the VG1-5, was one of the few semiautomatic Volkssturm weapons produced at the end of WWII. I have discussed these rifles before, but wanted to take advantage of the opportunity to take a close look at two more examples of the type.

Mechanically the Gustloff uses a system quite unusual in rifles — gas delayed blowback. Chambered for the 8×33 Kurz cartridge, there are 4 small gas vent holes in the front half of the barrel which vent gas into a chamber in the front muzzle plug. Pressure in this chamber acts to keep the slide closed, thus delayed the opening of the action. A nearly identical system is used in the much later Steyr GB pistol.

One of these in particular still has its original sling, which is a neat feature (the other clearly was issued with a sling but has lost it). In total 10,000 of these were manufactured, but they were not able to make a significant impact to prolong Germany’s war effort.

QotD: Farmers and slaves in ancient Mesopotamia

In one of my favorite parts of the book [Against The Grain], Scott discusses how this shaped the character of early Near Eastern warfare. Read a typical Near Eastern victory stele, and it looks something like “Hail the glorious king Eksamplu, who campaigned against Examplestan and took 10,000 prisoners of war back to the capital”. Territorial conquest, if it happened at all, was an afterthought; what these kings really wanted was prisoners. Why? Because they didn’t even have enough subjects to farm the land they had; they were short of labor. Prisoners of war would be resettled on some arable land, given one or another legal status that basically equated to slave laborers, and so end up little different from the native-born population. The most extreme example was the massive deportation campaigns of Assyria (eg the Ten Lost Tribes of Israel), but everybody did it because everybody knew their current subjects were a time-limited resources, available only until they gradually drained out into the wilderness.
