More explicitly, they are names given to a proposed solution to the problem of discrepancies between models and measurements. Measurements show that objects in the universe move in a way that isn't fully accounted for by the gravity of all the things that we can see (that is, the stuff emitting or reflecting light), so the proposed explanation is that the discrepancy in motion is due to the gravity of things that isn't emitting or reflecting light.

This is a hypothesis. It fits the facts we have so far. We still have to find evidence that the hypothesis is correct, or that the hypothesis is wrong. That's how science is done. You come up with a hypothesis that fits the measurements you have, then you look for ways to see if the hypothesis is correct.

Nuclear reactors use most surface water, not ground water.

Datacentres are no pickier. You can even cool a datacentre with saltwater, you just need a heat exchanger.

Also, closed loop does not evaporate. The loop is not closed if stuff escapes from it.

You're arguing with the actual terminology used in the nuclear industry. "Closed loop" or "closed cycle" designs have the water pumped in a cycle through cooling towers. The towers lose water to evaporation, taking heat with them, but the rest of the water is returned to be reheated again. "Open loop" or "open cycle" designs have no cooling towers. The water is heated and just discharged hot. They consume much more water (over an order of magnitude more), but most of that is returned. Closed loop are more common, but you see open loop in some older designs, and in seawater-cooled reactors.

"How often do you think I print?"

Seemingly not very.

I've printed many hundreds of kg on my P1S, thanks.

I do not consider having to write data out to a card and transport it back and forth between the printer and the computer to be the pinnacle of convenience. That's something that would be considered embarrassingly inconvenient for a 1980s printer, let alone a modern net-connected device. And it's designed to be inconvenient for non-cloud prints for a reason.

The geothermal plant already exists: https://www.globalelectricity....

Apparently, Microsoft was proposing to build the data center there and tap into the existing geothermal power, not build new geothermal power (the summary was a little confusing about that).

THAT SUCKS BRO

Also, anything sounds big when you put it in gallons. Doesn't sound so big when you mention that's 92 acre feet, the amount used by less than 20 acres / 8 hectares of alfalfa per year. Or when you mention that a typical *closed loop* 1GW nuclear reactor uses 6-20 billion gallons of cooling water per year (once-through uses 200-500 billion gallons, though most of that is returned, whereas closed loop evaporates it)

I don't think it has anything to do with that. As soon as I saw the headline, my mind went "cohort study". And sure enough, yeah, it's a cohort study. Remember that big thing about how wine improves your health, and then it turned out to just be that people who drink wine tend to be wealthier and thus have better health outcomes? And also, the "sick quitter" effect, where people who are in worse health would tend to stop drinking, so you ended up with extra sick people in the non-wine group? Same sort of thing. This study says they're controlling for a wide range of factors, but I'd put money on it just being the same sort of spurious correlations.

It would be an entire 7 years later before anybody managed to put a thermistor in the package to stop cpus from destroying themselves. An eternity in that era.

There are not many U.S. style SUVs sold in the E.U. anyway. They don't fit on many parking lots or in parking garages.

"I just put my models on a usb drive then plug said drive into the printer."

You must have a lot of spare time on your hands.

"It works great locally" - Um, no it doesn't?

They've made a nice easy-to-use ecosystem. For $400 you can get a P1S that supports adding an AMS, auto bed leveling, enclosed-chamber printing, high precision, high print speeds, and 300/100C nozzle/plate temps, and has an easy cloud print service and a robust ecosystem of models you can just download and print with no extra config straight from the app.

But yeah, their behavior is increasingly entering bad-actor territory. I wonder how long it'll be before they lock entry-level printers into their branded filament?

The difference is that electric cars and trucks primarily charge overnight, when the demand for electricity is low.

You don't need to improve the grid capacity to serve people charging when you have excess capacity available.
