Some people write their love letters with the "help" of a LLM. Politicians write speeches, teachers write their report cards, managers the reports on their underlings and so on. Except for having an empty mind and being an imbecile, there's not much of an excuse for doing so.

Interesting calculation. I think the efficiency loss in trying to cool all the way down to ice is probably not worth the benefit of a lower amount of water used.

Water heat capacity is about 4.2 kJ/kg per degree, so if we cool the water, say, ten degrees (C), for 4 kW of cooling for 12 hours we'd need about 4 tons of water (*). Seems like a lot, but water is cheap, and the tank would be a cylinder .64 meters radius at the base by 2 meters high, bigger than a home water heater, but still not too huge to put in your basement.

Ice would be better; the lower temperature would make heat transfer faster. On the other hand, you could circulate the cooled water in the same loop as baseboard hot-water heating, so in some ways it's simpler.

Ah, this again. Are you being paid by oil companies, who want to do anything possible to stop electrical vehicles?

No. The main pollution is not tire particulates, and electric cars are not particularly harder on tires than any American SUV. There turn out to be incentives to making cars larger and heavier. Eliminating these incentives would help, but (spoiler alert) it's not electric cars that are the problem.

No, it's partly right. Air conditioning loads tend to peak in the late afternoon, when solar power is still available (but not at its peak), but have another peak when people get home from work, which continues on into the evening and loads typically only drop below average around midnight, when solar is not abundant. Look up "duck curve"> .

This could, in principle, be easily solved-- air conditioners could easily store coolness. Water has a high heat capacity, and you could cool water during the solar peak, and use it to cool your living area in the afternoon. Water has low watt-hours per kilogram, but for residential or commercial use, that's not a big deal. But most of the US doesn't have time-dependent electricity rates, so there's no reason for consumers to want this.

Absolutely right, if by "renewables" you mean "solar". If we did have time dependent electrical rates, the cheap power is midnight to 6AM, not the solar peak at all.

But this may change as more and more solar gets emplaced.

If the resulting Rust code is human-readable and human-maintainable, then yes... I can see wanting to continue in Rust rather than C as a valid use-case.

Yes, I hate all the LEDs on devices and I too would black them out or sometimes even open the device and desolder them.

Then I discovered a magical thing called a sleep mask, and that solved all of my nighttime light problems.

If the C code does something unsafe, how can it be machine-translated into safe Rust, without knowing the intention of the programmer?

And even is this is possible, what's the point? Why not just make a C compiler that emits "safe" assembler directly? It's not as if a transpiler is likely to emit human-maintainable code.

I know Canonical is all hot for Rust, but this particular project doesn't seem feasible to me.

The problem is that there aren't enough of the little appliance-size batteries to economically recycle, but there are enough that sometimes they cause fire.

How many batteries per week do you think people in Britain discard?

Last time ivermectin worked like charm - maybe it also works against heat stroke? And coal, beautiful coal emits chills when burning.

yet people still claim (and some maybe even believe) that climate change is a hoax. Do something before it is too late. I used to think that it would affect my grandkids, not me (I am 71), but I am now not so sure - this Summer has been hot!

Yep. Traveling into the EU is far more pleasant than traveling into the USA, at least for me (Canadian).

One wrinkle is that if I ever travel to the USA (which I haven't done in a while and don't intend to do in future), I go through customs pre-clearance here in Canada. So if they start hassling me, I can just say "OK, I've changed my mind; I don't want to enter the USA." They can detain me for a bit, but ultimately they have to let me go, because I'm on Canadian soil.

We already know that there is water in permanently shadowed craters near the lunar poles. This has been well-proven by multiple missions, including the LCROSS mission that actually impacted the pole.

What we don't know is what the physical state is. Sheets of ice? Ice-coated grains of regolith? Deeply hydrated minerals? Fluffy snow? Layers of dust alternating with rock-like layers of minerals cemented together with cryogenic ice?

I don't want a car with any sort of touch-screen. In fact, apart from the backup camera, I don't want a screen at all. When the car is not in reverse, the screen should either be blank or showing GPS navigation. That's it.
