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.

I've read MRI scans require helium, and there is currently a shortage. It's not practically renewable or recyclable so far. If everyone gets an MRI it could cause a severe shortage.

I wonder if the tech can be reworked to not require helium or any other hard-to-find resource.

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.

FTFY: Don't use whitening agents. Your washer will implode.

Infrared are longer wavelengths. Probably too long to be trapped the way they describe. I immediately wondered about microwaves, i.e. radar. But those are way longer waves, so no as well. The reason they can put a mesh screen you can see through in the door of a microwave oven, is because the wavelength of those radio waves (that is really what they are) are so long they can't get through. Finally, black items can radiate heat, you just can't see it. So sure, if it trapped enough visible light, it could be 'converted' to a longer wavelength (infrared) as the fabric tries to shed the extra energy.

need to ban 3D printers

Ban 3D morons.

The M.E. has a way of driving everyone crazy; you are damned if you do and damned if you don't.

Put HAZMAT tape around the area and warn everybody away. Leave them on their own, giving them no food nor weapons; if they bonk each other to oblivion, it's their problem, not ours. I think it's God's Insane Asylum.

Non-nuts have migrated somewhere quieter, leaving mostly nuts in place, a Sanity Filter. I'm just the messenger.

do business with Israeli gov't. Regardless of your political stance, from a business standpoint it's just asking for drama and controversy of some sort.

Qualified to work at Boeing.

I simplified the story for ya.

Thanks for the tip! What about affecting GPS (navigation)? Does that use a separate antenna? If so, that would mean the vehicle has two different antennas for two different satellite types.

It's a smallish SUV, by the way.

MS playbook [of] shoving ads everywhere...

Ads on a desktop are one thing, but ads that block one's navigation map while driving are another. Thus, Sirius found a way to be even more evil than MS. Quite a feat.
