In an upshot, theres a constant roughly 10 millihertz hum worldwide,
detectable by seisometers, that goes up and down. its created by...
WAVE ACTION. that is, waves in the ocean. And its rise and fall and
appearance in different areas inland is caused by storms and such
moving main masses around. Thought some here might find that
interesting, in comparison to THE HUM.
I've often wondered if the Taos hum is due to synchronization of
electric transmission lines throughout the western US. If you put
water in a pan and tap the handle you see the waves converge
amplified in the middle. If every electric motor, and every
transformer around for hundreds of miles is synchronized, then the
cumulative effect in producing sound could be large, especially if
there is a large radius comparatively devoid of devices surrounding
the hearing point and then a large circumference of active electrical
devices.
This makes me wonder what the Kepler might see on some distant planet
surface.

If a well developed planet is using an electric grid, its
distribution frequency will likely be in the 50-60 Hz range, the best
trade-off frequency as calculated by Steinmetz for GE I think. If it
uses an AC lighting system, perhaps the night side will show this low
frequency amplitude modulation of its night lighting. I don't know if
Kepler could detect this kind of thing, or the flashes of huge
lasers, whether intentionally aimed here, or involved in laser wars...
