I remember seeing a study mentioned on Green Car Congress about the lifecycle costs which I remember cleaning and repairing those mirrors (made to very exacting precision) required significant human intervention and expense. Also the total EROEI was very close to zero. And, as Don didn't mention photovoltaic, I assumed the use of molten salt Stirling systems. I don't know if laminates were considered in the calculations. The stow systems are also prone to breakdown and not just due to the sand in the bearings issue.<br /><br /><br />Overall, these systems are very complex, require significant manual intervention, are prone to failure, and make nice easy targets for militaries and criminals.Dale Asberryhttp://life-abundantly.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-11539837.post-82231609806028043072012-05-16T15:54:13.590-05:002012-05-16T15:54:13.590-05:00"supercooled capacitor storage/supercooled ca..."supercooled capacitor storage/supercooled capacitance flywheels" = ???

Contemporary systems have active and stow configurations - in the event of haboob - you temporarily stow the reflective surfaces.<br /><br />2. Polymer laminates can be deployed in these circumstances with shockingly durable moisture and abrasion resistance. <br /><br />www.reflectechsolar.com/pdfs/FAQs(ReflecTech).pdfCNuhttp://subrealism.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-11539837.post-11843278163312153982012-05-16T11:27:02.909-05:002012-05-16T11:27:02.909-05:00I was not up on that, thanks for the heads up.I was not up on that, thanks for the heads up.John Kurmannoreply@blogger.comtag:blogger.com,1999:blog-11539837.post-2480977615800787872012-05-16T10:36:53.274-05:002012-05-16T10:36:53.274-05:00Actually, Don has nailed this one on the head.

Iron superoxides, if crafted correctly, are very promising. Then, of course, there is the nickel/molybdenum/nitride families that can give platinum and gold catalysts a run for their monies. We just may finally be entering the golden age of chemistry. And then, of course, there are the metamaterials applied to phononics - superefficient heat concentrators and insulators that could make today's stuff look Stone Age. Lots of room for improvements in the solar concentrator area.John Kurmannoreply@blogger.comtag:blogger.com,1999:blog-11539837.post-83426453301397549132012-05-16T08:08:10.542-05:002012-05-16T08:08:10.542-05:00If I were the Saudis, and clearly I'm not, I w...If I were the Saudis, and clearly I'm not, I would focus nearly exclusively on solar concentrators, stirling motors, and supercooled capacitor storage - and forget about the photovoltaics.CNuhttp://subrealism.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-11539837.post-64084624499963738132012-05-16T06:27:07.936-05:002012-05-16T06:27:07.936-05:00 There are big problems with the desert.

Also desert windstorms sandblast optical surfaces, permanent damage. Security is a problem - a Saudi desert's worth of electrical hookup is a lot of copper to patrol/protect.
