lets do the powersat calculations again, just for fun <img src="/images/icons/smile.gif" /><br />Based on this:<br />http://www.powerfilmsolar.com/products/oem_components/modspecs/rc7275psa.htm<br /><br />I get about 325grams per square meter, or 325 tons per square kilometer.<br />about 40 watts per square meter, or 40 megawatts per square kilometer.<br />I believe i have seen 10 megawatt "demo" designs proposed, that would be "only" roughly hundred tons to launch just counting the film material.<br />The film is rollable, so deployment shouldnt be complicated, but how to make it rigid, inflatables ? Or maybe there wouldnt be any need to make it rigid, just add stationkeeping solar-electric thrusters at the corners that pull the "fabric" under constant small tension, and if this isnt enough, weave tethers through it.<br /><br />Cooling be a major obstacle though, i have no idea how much sunlight this would absorb as heat at full incident angle in GEO, and how much would need to be dissipated.<br /><br />This is just a BOTE calc based on the commercially available current product. There are always other thin-film products coming on market, could be that some of them weigh significantly less.
