I am so grateful to Cryptogon for leading me to this:<br><br><!--EZCODE LINK START--><a href="http://pesn.com/2005/08/02/9600142_IAUS_Solar/" target="top">IAUS Pushing Solar to Within Competitive Range of Grid Power</a><!--EZCODE LINK END--><br><br><!--EZCODE ITALIC START--><em>There are two key factors in the IAUS technology that enable a cost-effective conversion of solar energy into usable power: their thin-film solar collectors, and their bladeless turbines, which have a much wider application than just converting solar thermal energy to electricity.<br><br>The company also will be combining this new development with existing catalytic technology to generate methanol fuel cleanly from carbon dioxide and hydrogen. All this can be done at a price comparable to gasoline, if not even a little less expensive, considering the present high price of gasoline.<br><br>The solar collectors do not operate as photovoltaic cells. Rather, the sun's rays focus onto a heat exchanger which then transfers the heat to a highly efficient turbine, which in turn hooks directly to a regular AC electricity generator. <br><br><br>Solar panels resemble magnifying glass lenses. Approximately 1/8-inch thick, resilient material, withstands strong winds. <br>Though the panels resemble a magnifying glass, they are in fact composed of thousands of microscopic refracting lenses on a thin substrate that is only about 1/8th of an inch thick, and held in place by a frame. The "thin film" manufacturing process is far less expensive than the photovoltaic cell manufacturing process.<br><br>The prototype is rectangular in shape, with 15 panels on each half, each focusing on a separate heat exchanger that will reach around 1000 degrees Fahrenheit, driving the turbine.<br> <br>However, the manufactured product will be shaped like an octagon, about 22 feet in diameter; and will focus all the rays on a larger heat exchanger, which could get as hot as 4000 ºF. That unit will put out about 6-10 kilowatts of AC power, enough to power a few homes.</em><!--EZCODE ITALIC END--><br><br><br>The technology seems simple. The part hardest for me to grasp is the hydration-dehydration process that creates electricity when the sun is hiding. With the efficiency at only 20-30%, this thing will become even more powerful as they hone the technology. <br><br>It sucks that they're rolling it out exclusively for the power companies. If they'd roll it out for the people the big power companies would disappear.<!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"><!--EZCODE EMOTICON END--> Yay! Imagine that! One corner of your backyard devoted to something like this that would furnish enough power for 3 homes, and clean! <br><br> <p></p><i></i>
