Allen, here's a teaser. I emailed Lockheed last week asking about who might be furnishing the solar panels on their surveillance airship, and I got this reply today... Dear Del: Thank you for your interest in the High Altitude Airship program. We plan to use thin-film photovoltaics that conform to the shape of the airship envelope. We are in the design phase. Cary Dell Lockheed Martin Maritime Systems & Sensors Communications Manager 1210 Massillon Road Akron, OH 44315 330.796.8458 (tel) 330.796.3274 (fax) I didn't really expect them to divulge who they are working with, but I have a good guess. From Unisolar's web site.... "United Solar is investigating the use of lightweight Kapton® polyimide as a substrate to make extremely lightweight cells. This developmental program is aimed at producing modules which can generate >2000 W/kg at 10% efficiency. Two approaches are under investigation. In the first approach, cells on Kapton® having a structure similar to the stainless steel cells have been demonstrated in the research lab with 9% efficiency and specific power >1250 W/kg. The second approach on Kapton® uses a laser-interconnection process to build modules which can potentially supply 2500 W/kg. Funding for this program has been provided by the US Air Force." uni-solar.com Del
