Comment Re:Now we're just haggling over the price (Score 1) 76

But last I read of it, it goes into a fund controlled by the President -- a slush fund, in olden terms.

Where did you read that? If it's true it would be momentous. A totally discretionary fund of $2-6B per year (based on nVidia's projections of selling $2-5B per quarter to China) would give the president enormous unchecked power.

I've spend some time searching and haven't found anything to substantiate this claim. I'm not saying you're wrong, but I'd like to see where you got the idea from.

Efficiency is based on differences in energy that are economically accessible, not on some rambling theories in a newline-free paragraph.

You can access room temperature. You can' economically access the blackness of outer space from the earth's surface. Likewise, you can access the negative terminal on your battery, but not some static charge in the upper atmosphere.

You pump X amount of energy into a heat engine, it expels that energy to an accessible exhaust, and typically 70 to 95 percent of that energy is *not* converted to work. You pump X amount of energy into a battery, it dumps that energy through a motor to its negative terminal, and only 5 to 10 percent of that energy is not converted to work. That's the only way to practically analyze the situation.

We could also all have infinite free energy if we could access the levels below the zero point energy in the quantum fields. One little problem: that's not accessible either.

Comment Replace CEOs with AI! (Score 0) 31

We need to push for CEOs to be replaced with AI. They'd do a better job and would cost a LOT less.

Start repeating this everywhere and get the meme-makers on it. It will be wonderful to watch them squirm as they suddenly find reasons why AI shouldn't replace a company's most valuable assets: its most highly-paid executives.

For the example in TFS of 200F water and assuming room temperature exhaust, Mr. Carnot says that the max possible efficiency is less than 20%. Any real world engine, including this one, probably ends up at a low-to-mid single digit percent efficiency. IOW, the vast majority of the heat would still be wasted.

The operator of the facility generating the waste heat might get more energy savings at lower cost by tweaking their processes to be a few percent more efficient in the first place, instead of trying to recover this low-grade energy source with an elaborate engine and plumbing.

Just put it in context: Today Russia struck the Pechenihy Reservoir dam in Kharkiv.
Russia launched the war because they thought it would be a quick and easy win, a step towards reestablishing a Russian empire and sphere of influence, because Putin thinks in 19th century terms. Russia is continuing the war, not because it's good for Russia. I'd argue that winning and then having to rebuild and pacify Ukraine would be a catastrophe. Russia is continuing the war because *losing* the war would be catastrophic for the *regime*. It's not that they want to win a smoldering ruin, it's that winning a smoldering ruin is more favorable to them and losing an intact country.

Before NT, Windows was an absolute mess. I think the only reason most people put up with it was that they didn't know anything better was possible and since Windows was so widespread it was a misery everyone shared.

I think that many of those people were also recent DOS users. Given that DOS systems would often simply freeze up several times per day and require a reboot (easy to do since any bug in the user's application could do this), once they added a protected mode pseudo-kernel to Windows (maybe starting with Windows/386 2.1), it was actually a slight improvement over what they were used to since DOS crashes could sometimes be isolated to one virtual terminal.
