Lockheed's High Altitude Airship

swordboy writes "Lockheed Martin has just awarded a contract to UniSolar Ovonic regarding development and delivery of flexible, lightweight solar cells for the U.S. government's High Altitude Airship security project. The proposed 500-foot-long dirigible is to fly at a stratospheric 70,000 foot altitude - above both jet stream and severe weather. The thin-film solar technology, although low in peak conversion efficiency, can potentially deliver a whopping 2500 watts/kilogram. This is the same technology as the previously discussed GE organic LED project - just with the physics in reverse. Broadband communication blimp, anyone?"

"many 3rd world ground forces are even going to spot it"

After all, for some truly *bizarre* and unfathomable reason, 3rd world nations pose the most imminent and dire threat to the security of the United States of America.

Yeah yeah troll, flamebait, *whatever*.
