The US Army is currently testing solar powered tents. Hauling a generator up a mountain isn't very convenient or practical, so that's where this idea bloomed. They are testing three tent models currently;
The first, TEMPER Fly, 16 by 20 foot tent that can generate 800 watts of electricity.
The second, QUADrant, is a smaller version and can generate up to 200 watts.
The third is Power Shades, able to generate up to 3 kilowatts of exportable power.
This is kind of cool. Just another reason for me to escape to the middle of nowhere and live out the rest of my days playing my Xbox 360, while I'm not out hunting and fishing.
