If I can speak for my Generation (GenX), for a moment: (abridged version) Fuck you, Boomers and fuck you Millenials.
The Baby Boomers for really screwing us over, several times. I look forward to the retirement homes we're going to toss you into on the budget you gave us.
Every generation says this to the generations before it. What'll be fun is when the next generation tells you to fuck off:)
Oh lord, that's absolutely ridiculous. Plenty of cities have privately run disposal, and you don't see that in those cities. You should really try to pull that stuff over when the experiment hasn't been done for decades already. You sound like someone who's lived only a few places in their life, and just doesn't realize there's variation on your presumptions in other places.
You wanna know what happens? They pay their bill. Even a lot of meth heads know the garbage needs to go away, and pay it before drugs.
Actually, the voltage drop off of a LED is ~1.2V (This is a physics issue; use germanium, and the drop is 0.8V.) When you run an LED off of a 5VDC line, let's not forget the 330 ohm resistor in series with it, so that the 1.2V appears across the LED. And you guessed it! That resistor has the exact same current running through it, and it's wasted as heat. Bump it to run off of 12V, and you're putting an even larger voltage drop across the resistor (10.8V) wasting heat -- so now you're wasting 90% at 12V.
A/C skin effect applies *based on frequency*; I assure you skin effect at 50/60Hz, even at high voltages, is negligible -- Doesn't matter if it's 420kV or 4.2V. A circuit at 29.350 MHz at low voltages has to worry a LOT more about it than a 50/60Hz line voltage. (And it really starts kicking off at the start of the microwave range, 300MHz, and is exceptionally important by the end of the microwave range 3GHz.)
The reason A/C is used is based off of Ohm's law and is based on current and resistance; Jack up the voltage 1,000x and you can reduce the current (and therefore, heat loss) 1,000x.
I've made 10+ calls like this in my history of amateur radio/scanner listening. I know others that have as well. It's actually pretty common. Good example is looking for a possible drunk driver or car of interest. Quick phone call "Yeah, I just passed them on I-foo at milemarker bar"
Great job/.
Can we now get more current news from the 90s? Police have been moving to encrypt their radios since the late 80s. This is not news. In fact, good chance a lot of people commenting on this were born *after* police started using it.

Exactly.
