Schools of Fish Inspire New Wind Farms that Will Increase Energy 10X Every now and then you come across an article and concept that makes you really smile and feel good on the inside. Typically they are "feel-good" stories that you see online or on the news, but today I came across this story about how scientists have designed new wind farms based on how schools of fish swim. So not only are we creating technology to help the environment but we are looking at nature for help. The new vertical-axis wind turbines are designed by Caltech and are currently being tested in the California desert. Here is a little statement from a Caltech engineer: Additionally here is a statement from the author of the study: Read more about the new advance over on the BBC
Wind Turbine Output Boosted 30% by Breakthrough Design Clean Power Published on April 29th, 2009 | by Timothy B. Hurst Passive structure design of “Wind Energizer” by Leviathan Energy reportedly increases wind turbine efficiency 30% in field tests. Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about it. The principle theory at work is that by placing passive objects around a wind farm it will change the circulation around a large wind turbine. “This is a disruptive technology,” Leviathan Energy CEO Dr. Farb is a bit of a modern day renaissance man. The Wind Energizer is a donut-shaped structure made from steel and plastic, but the exact dimensions of it depend on site-specific data, like the tower height, length of the blades, prevailing wind direction and intensity, etc. Images courtesy of Leviathan Energy Timothy B.
Torresol Energy - Gemasolar thermosolar plant Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology. Characteristics of Gemasolar: Rated electrical power: 19.9 MWNet electrical production expected: 110 GWh/year Solar field: 2,650 heliostats on 185 hectaresHeat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed. The prolongation of the plant's operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar's output much higher than that which is delivered by other technologies in a facility with the same power. The notable increase in the plant's power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies.
