Odysseus: a Z-shaped solar aircraft, built for DARPA
DARPA, the U.S. Defense Advanced Research Projects Agency, has set a seemingly impossible task, known as the Vulture program, by calling for an aircraft which can remain in the sky for five years while generating five kilowatts of power for a 1,000 pound payload. The Odysseus by Aurora Flight Sciences, which has been selected as one promising design by DARPA, doesn't appear capable of flight at all to many onlookers. The odd Z-shaped wing is actually three separate machines which can change their combined shape in order to catch the suns rays throughout the day and flatten out at night, when the Odysseus would fly on battery power alone. Together, the three sections would span almost 500 feet. Advanced composite materials and double-sided solar panels are employed to make the concept appear possible. If DAPRA's vision proves successful, aerial vehicles like these could take the place of satellites for surveillance and communications purposes.[Sources: Flight Global, Gizmag]

"If DAPRA's vision proves successful, aerial vehicles like these could take the place of satellites for surveillance and communications purposes."
Ugh. The idea of dozens of these monstrosities flying over urban areas is a hideous vision of a future I hope doesn't occur. It's the length of 1 2/3 football fields, for cryin' out loud.

Hank: I think it would be so high up you would be hard pressed to see it. Would you notice jet-liners if they didn't have vapor trails? (electric motors don't leave vapor trails).

...and they fly 3 times as high...

I like the concept and it seems that it could prove handy especially in long term spy operations. There is no noise , very hard to detect because it woudl fly so high and it needs no fuel

Well, for one thing latency to satellites is far too large for useful broadband internet. It's fast but high latency. Solving this problem would be huge.

Just duct tape on a couple Airport Extreme Base Stations and there ya go - global broadband from the heavens!
