Just been reading about this, called "Silent Guardian"....

I got to get me one of those. :yh_devil

heck this base is right by me......:-2

Perhaps what you really want to know Scrat, is if the Government ever intends to use it on American Citizens?

Now's a good time to buy tinfoil jumpsuits. If that beast pushes out 2 or 4 micron infrared, tinfoil will reflect it all. Those are the wavelengths that get through the air without being absorbed. Any shorter and it'd be visible or ionizing radiation, any longer and it'd penetrate skin far more than they say - if it were millimeter technology it'd penetrate far deeper and the atmosphere attenuates those wavelengths so much that you'd see shimmering air where it got so excited.

I bet there's a line of raybans that does the same for keeping your eyes clear too, so if you see a bunch of people wearing tinfoil hats and cool shades in future you'll know what's deployed around the corner.

In that case I'm right, the 1/64th of an inch skin penetration is total nonsense, the energy will get halved for each unit of depth but that's a lot of live cells being destroyed in the process if they reach 50 degrees Celcius even for a short while. That's a terahertz transmitter? Then the air *will* shimmer, especially if it's humid that day, atmospheric attenuation is significant. If there's even a slight drizzle the air will go a stage further and steam, the operator will need to up the power by a factor of ten to get the same effect over that range, the millimeter waveband is so mopped up by water molecules (unlike the 2 and 4 micron windows). The only thing they have in common is they're reflected by tinfoil and they melt mars bars.

Does it qualify as a weapon, this box of tricks with a dish? If it doesn't, could the protesting crowd deploy one at the next G8 summit protest or would that just be unsporting?

ROFL!
