I saw that shade cloth stuff and wondered how well it might work as a collector element.
After looking at the close up pictures in this link Amazon.com: EasyShade Sunblock Black 40% Shade Cloth UV Resistant 6ft x 50 ft: Patio, Lawn & Garden http://ecx.images-amazon.com/images/...L._SL1500_.jpg It seems like horizontal strings with floppy thin flat strips of reflective plastic, connecting the strings. It seems like air flow might be a lot higher than my 80% screen. Which isn't idea for the collector design I'm thinking of using. It might work, if it's not too reflective and can stand up to the temperatures inside a sealed collector box. Gary didn't like the out-gassing he got with the FG screen.. New Page 1 He thinks it might have been a film or coating & not the screen itself. He's interested in testing the Suntex screen. (per his Email). In one of the reviews of the Suntex 80%, the reviewer said he had switched to using the 90% screen and found it was thinner and easier to work with. That sounds real good to me. Price isn't too much of a problem, since I'm not going to be building more than a single 4x8 footer. That is, if I can sell the idea of a front-yard install location.. Which may not be possible. Unless the winter drags on until late June.
