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.

Once you import numpy, Python has arrays.

That would never fly. You just know that some dufus at the gym would bring a 10kg steel dumbbell into the MRI room and ruin things for everyone.

They tried, but quarreling parent groups couldn't agree on whether to teach the kids that they were coding with 3 registers or 259 registers.

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.

I presume you're referring to the 2008 Chinese Milk Scandal? I'll point out this was something perpetrated by the Chinese industry, not American. It was knowingly covered up with the complicity of the Chinese government to prevent it from embarrassing the ongoing Olympics. Only when the scandal became impossible to cover up did the CCP take any action.

As of December 2025, San Francisco Mayor Daniel Lurie and former Mayor London Breed have both expressed praise for China and the relationship between San Francisco and Chinese cities.

But I was told that the sole reason insurance rates are high is because of BIDEN!!!!1!

I bought a nice pair of gloves this year with ChatGPT, but when they arrived I found that they each had six fingers.

The chlorophyll in plants is finely tuned to absorb specific wavelengths of light. It already has a hard time with green light compared to blue light, and it's simply not going to work at all with radiation that has wavelengths that are orders of magnitude shorter. Chlorophyll acts like a little antenna that gets excited by certain light frequencies, but ionizing radiation would just blow the chlorophyll molecules apart and destroy them.

Taking advantage ionizing radiation is going to require a completely different mechanism than plant photosynthesis, just like you can't use glass lenses or parabolic mirrors to focus X rays or gamma rays. Plants probably have no more chance of having such a mechanism than fungi do.

IOW: "We've only got $3.5T in capital to work with, so this is just too hard for us to figure out. You'll have to switch to an OS made by unpaid volunteers."

We should call it "job incomplete".

Most common metals have a simple one or two syllable name: Iron, Copper, Tin, Zinc, Lead, Nickel, Silver, Gold, etc.

The USA recognized that to some extent and got started by chopping off one extraneous syllable, paring it down from five to four. However, once it was realized that Al would be a common everyday material like iron, we should have gone ahead and pruned it all the way down to two syllables, maybe something like "Alem".

Not nearly as irritating as having dozens of random dot subdirectories in the root of your home directory.

The first issue costs a few developers a few days of their time to fix. The second is a problem that nags millions of users for eternity.

Because at this rate, by my math, the number of AI cores Google requires will exceed the number of atoms in the visible universe within about 120 years.

What I typically do is leave in the no-name AAA alkaline batteries that the remote came with, and it works for a couple of years until I move on to newer gear.

Then after I've left it idle for 15 years, I'll come back and open the remote to discover that the batteries have leaked all over the inside and destroyed it.

If it was a reasonable balance of risk and payback, then they could get a private loan like everybody else.
