The U.S. military runs a facility, way out in the woods of Alaska, that beams hugely-powerful radio waves into the ionosphere.
Depending on who you believe, this High Frequency Active Auroral Research Program (HAARP) installation blasts out these transmissions in order to learn more about the electrically-conductive layer of the atmosphere. Or HAARP is designed to spy on unwitting foes, control the weather, and spew out death rays.
In either event, HAARP wasn't the first installation of its kind. The Soviets had their own, high frequency ionospheric research center. It's now abandoned, mostly. But the pictures of the place are very much worth a few clicks.
