why not plain old 12VDC?
Because a cigarette-lighter connector is noisy and unreliable! Sheesh, I hate them.

According to Wikipedia, the resonances occur at extremely low frequencies (ELF) around 7.83 (fundamental), 14.3, 20.8, 27.3 and 33.8 Hz. That's Hertz, not megaHertz. Now, how can we tune them in? I, for one, do not own a radio that can receive those frequencies.
Researchers at Stanford University have invented ONE HALF OF A BATTERY....
How the heck do you pronounce "Duqu"?
I like this idea a lot. And it seems like an excellent project for an Open Source Hardware community to develop a flexible platform for sliders, knobs, and switches to interface with a PC or Mac. Then anyone who wanted sliders, knobs, and/or switches wouldn't have to re-invent the wheel.
"in communities with low unemployment"
What the heck does low unemployment have to do with super high speed access?

``Yeah, we don't use "antennae" 'round here.
What is with people who insist on the -ae?
IT'S ANTENNAS, FOLKS!!!
...they are translated into Imperial units...
No they aren't. They are translated into United States Customary Units. Imperial Units are used in places like England and Canada, and differ from United States Customary Units in volume (ounce, pint, quart, gallon) and mass (stone, ton).
Yes. According to Wikipedia, "It completed more than 700 orbits over seven weeks."
Note to OP: 2 != 7
Well, I suppose we could call it Aurora Equatorialis.
I agree! These guys did something quite fantastic, and just because they can't clearly explain the mathematics to us doesn't detract from the fact that they did it!
Hopefully scientists will find time to develop the theory and publish it. Until then, I think it's just like living in 1904, when the Wright brothers first flew a powered aircraft.
An adequate bootstrap is a contradiction in terms.
