Free energy harvester device
The Daily Mail (and Drudge) are pimping this story about free energy
..The Duke engineers used metamaterials, which their press release describes as 'engineered structures that can capture various forms of wave energy and tune them for useful applications.'
They say the device harvested microwaves with an efficiency of 36.8 percent, similar to modern solar cells that capture light energy...
All this is a fancy way of saying efficient antenna for anything in the EM spectrum. Shove a wire'ish thing in a field and you can induce current on it.
If you're kinda sneaky, you can even do things with that current...like examine any modulation it might have. i.e. SPY/SNOOP on whatever is broadcasting if its got something worth snooping.
Years ago, back in the late 80's I dabbled with some gear that could read the contents of a computer screen remotely just by the EM signals it was emitting. Interestingly, the monitor could be completely unplugged from the test machine and the screen could STILL be read. The video card itself was a strong EM emitter and could be picked up too. Pretty much any display that driven by a RAMDAC and operates with scan cycles, and isn't tempest certified is going to be emitting something that can be collected.
To thwart EM leakage that can be ahem..."harvested" you pretty much have to enclose the device/system in a Faraday cage. All your really rad spook installations will be wrapped with some manner of Faraday cage to prevent this harvestable leakage.
