This is the HAARP of the 21st Century's Sirens. The idea is to beam up more microwaves than can be found concentrated in vast magnitudes beyond anything found in nature, just to see what'll happen (duh) and to see if it can be used to fight missiles, zap the earth for oil and maybe even modify the mental, emotional states of masses of people.

In the video documentary, be sure to check out the dumb-ass expressions on the lead scientist's face when he's asked about the threats in this clip's title.

A project brought to you by the US Air Force, HAARP is sited in Alaska, so they can be as close as possible to the lowest points in the earth's atmosphere, as evidenced by the Aurora Borealis (Northern Lights). Part of the project involves try to lower that part of the atmosphere even more.

Apparently, there are about 55+ around the world.
Even some that are portable.

If I can dig out the source of this information I'll clip it.

I've updated the blog entry from which this clip was originally clipped to include the information in my last comment and more and to try improve the clarity of the information presented. See http://h0lug.sourceforge.net/h0blog/?p=469
