Why can't someone borderline insane be for the sterilization of the insane? Keep in mind that he had no partner or children, by choice... or barring that, that it's pretty common for people with an odd outlook to think of themselves as normal or proper.

Parts of Canada kept sterilizing mental deficients through the 70's, he would have been proud.

Piezos have a very narrow resonant frequency, so if you try to make a broadband white noise it's very inefficient (and I presume would mostly still be audible only at the resonant frequency).

Cheaper than speakers and easy to drive, so... like everything else I guess... 'good enough'.

FWIW the walk lights here are mostly high pitch, but more than a few feet away I only hear a sort of metronome clicking, as the high part gets lost in traffic. So they must have some low component as well. (or i'm half deaf up high, maybe...)

PoE, the standards complying versions at least, 802.3af (IIRC), do run at 48V. As it is about the highest you can go with shit insulation and not be required to meet real safety standards, while at the same time battling I2R losses with get brutal on long runs with low voltages.

I agree though, unless a room only has one 20W lamp, CAT5 isn't the way to be powering it...

If we want to save copper, we should do what we do now. Wire houses with 220V, and switch down at the load.

Just as in WW2, they had laws illegalizing looking for radio transmissions by saying that it's illegal to capture transmissions NOT MEANT for you. And other such hamfisted means. They would have made Dick Cheney proud.

Whereas the US just cut the shortwave coils out of German immigrant's radios. The american broadcasts were ridiculously scripted as well.

A lot of stuff 'flew' during the war that people wouldn't normally stand for, like say, internment of 'enemies', food & fuel rations, etc.
