Comment Re:DC transmission lines? (Score 1) 183

I was a high power radar transmitter engineer, and I've had to look for these coronal discharges in 40-50 KV power supplies, where the clearances were tight and corona starts a breakdown process. I had to sit in the total dark for several minutes until I could see it, guided by the sound and possibly smell.

The discharge from a big tesla coil is the same kind of thing, but high frequency AC. Faintly noticeable, unless you get a low resistance path to discharge it, like static discharge when you walk across the rug and touch a light switch. Or lightning.

If you walk next to a big power line you may hear the discharge. If it freaks out the deer, too bad. They can cross under the line away from a discharge point.

No. The beacon signal has nothing to do with the primary radar, except that the antenna is usually located on top of the radar antenna, and uses the same azimuth pointing information. The interrogator is transmitted in a short pulse, and when the plane receives it, it generates its own fixed amplitude response pulse which has its squawk coded into it. It is received back at the ground radar antenna and decoded and displayed, next to the primary radar return. The code gives the 4 digit squawk, plane altitude (which the radar can't detect), and other info like whether they've been hijacked or their radios are dead.

What Neil Young "discovered":
Basically, don't run your music through crappy mixing boards, filter the good parts out, or compress the shit out of it, or use lossy compression,and it will sound better. You don't need gold plated cables or vacuum tubes.

... has mountains, trees, and cows. My commute is 13 minutes through rural country. I cross country ski out my back door. Housing costs a quarter of what it is in Seattle. As for fresh water, I have 8 inches of it on my driveway right now, you can have all you want, just have to melt it first before drinking.
