Schools of Fish Inspire New Wind Farms that Will Increase Energy 10X

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. Based on early tests, the new design actually helps increase energy output by 10X and could be the wave of the future for wind technology. 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 Related:  WindFree Power

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.

BuildItSolar: Solar energy projects for Do It Yourselfers to save money and reduce pollution 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.

Solar Slab Using large super-insulated water tanks to inter-seasonally store solar hot water is popularly known as the Sonnenhaus concept in Germany, Austria and Switzerland. The water tanks vary in size from 40,000 litres for a standard house to up to 200,000 litres for apartment buildings and usually cost between £1.50-£2.00/litre. Sonnenhause owners boast heating bills 50% lower than the occupants of Passive Houses. The Solar panels and Water tank can be a costly addition to the construction budget and they can take up quite a bit of room. In order to explore this concept a super-insulated 10,000L Hydro Thermal Energy Store (below) was connected to 24m2 of Solar tubes in Cork in 2008, this reduced the clients heating/hot water bill by 65%. 24m2 of drain-back solar thermal tubes heat the water in the tank which reaches over 90 degrees most summers. A 12V PV powered pump fills the drain-back solar tubes with water when the sun shines, so there is no need to use antifreeze. Solar Slab Passive Slab

Wind power could drive the world As the world seeks to lessen its reliance on fossil fuels like coal and natural gas, renewable energy sources like wind and solar power are being developed as alternatives. Contrary to some other recent studies, analysis of climate data in the Proceedings of the National Academy of Sciences indicates wind turbines could harness hundreds of terawatts of electricity, far more than is needed to power the globe, even when accounting for the interplay between the groupings of turbines in so-called “wind farms.” To reach that maximum potential, according to study author Mark Jacobson, it would require 1.5 billion massive windmills to be installed on and offshore. That’s far more than you would need to meet the world’s actual energy demands, the Stanford University engineer qualified, but you would still need many millions more turbines than currently exist. Jacobson envisions a very different future. “The world today produces 70 — 80 million cars every year. But experts were skeptical.

Solar Energy Job Growth Outpaces Other Industries California is home to the largest advanced energy industry in the country, according to the first-ever industry-wide survey released today by the Advanced Energy Economy Institute. At 431,800 jobs today, advanced energy is bigger by employment in California than the motion picture, television, and radio industries; mining and quarrying; semiconductors; and aerospace. Advanced energy jobs grew 5% in the past year – more than double the overall state job growth rate – and is on track to grow 17% in the coming year, to more than 500,000 workers, based on employer hiring plans. While California is widely recognized as a national leader in energy policy, jobs directly related to the industry have not been quantified until now. The survey of more than 2,000 businesses, conducted by BW Research Partnership, a workforce and economic development research firm, found that, among the 10 states that have studied these industries, California has the largest advanced energy workforce in the country.

Wind Power Breaks Records In Spain -- Produces More Electricity Than Any Other Source For 3 Months, & Breaks 6 TWh in January Clean Power Published on February 6th, 2013 | by Zachary Shahan Denmark, the US, and Germany aren’t the only countries breaking wind power records these days. Spain is also a notable leader seeing strong wind power growth. In fact, it just saw its wind farms produce more electricity than any other source for a 3-month time period, for the first time ever. “Since Nov. 1, wind has been the top technology in the electrical system,” the Spanish Wind Energy Association (SWEA) was quoted as writing on its blog. Additionally, data from grid operator Red Electrica de Espana concluded that 6 terawatt-hours (TWh) of electricity had been generated from wind in January, another first for the country. In total, SWEA noted that 6 TWh of electricity was enough to power “enough to cover the electricity consumption of the majority of Spanish households” and that it “could cover the annual electricity consumption of countries like Honduras and Bolivia.” About the Author

Vertical Axis Wind Turbine Generator Energy VAWT | Vertical Shaft Axis Wind Turbines VAWT Generators Energy Shafts Mills Windmill Power Mill Windmills ...Agriculture Solar™ has been examining new wind energy systems to pump the large volume of water needed for irrigation. One new Agriculture Solar™ system uses a vertical­axis wind turbine to generate electricity that is compatible with utility grid power, and the pump is powered by this electrical system using a conventional electric motor. Agriculture Solar™ Vertical Axis Wind Turbines"VAWTs" can catch the wind from all directions and at lower wind speed than horizontal axis ones. There have been two distinct types of Agriculture Solar™ vertical axis wind turbines VAWT: The Darrieus and the Savonius types. The Darrieus rotor was researched and developed back in the 1980's. New types of Agriculture Solar™ vertical axis wind turbine machines VAWT are being introduced such as the helical types particularly for use in active environments where they would be considered safer due to their lower rotational speeds and since they can catch the wind from all directions.
