SheerWind's INVELOX Wind Turbine Can Generate 600% More Energy Than Conventional Turbines US-based wind energy company SheerWind just unveiled the INVELOX – a tunnel-based wind turbine that can produce up to 600% more power than traditional wind turbines. The company states that after extensive field-testing, their new INVELOX turbine “significantly outperforms the traditional turbine” and could reduce installation capital costs to less than $750 per KW. The INVELOX energy system works by capturing ground-level breezes and funneling them through a tapering passageway that naturally accelerates wind flow. Unlike other turbines, it also minimizes environmental and animal impact, and it requires no government subsidies to be profitable. All of this makes INVELOX a potentially game-changing renewable energy solution that could be easily integrated within commercial renewable energy operations. SheerWind claims that the INVELOX turbine can operate at wind speeds as low as 1 mile per hour, and it has generated a record high energy production capacity of 72%.

Tesla Technology: 5 Bladeless Turbines About To Revolutionize Energy Production Tesla Technology: 5 Bladeless Turbines About To Revolutionize Energy Production “Every home in America can run on wind energy. In fact these units can be installed on existing power poles in rural areas, to catch the wind and send its energy back to the plant.” - Raymond Green, Inventor 'Wind trees' could replace controversial giant turbines in race for sustainable energy An artificial 'wind tree' has been created to generate electricity from even the slightest flow of air. Jérôme Michaud-Larivière, founder of the Paris-based start-up NewWind, has created Tree Wind and plans to market the invention next year. The eight-metre high (25ft) tree consists of a steel trunk, from which extend branches holding 100 plastic 'leaves', AFP reports. "The idea came to me in a square where I saw the leaves tremble when there was not a breath of air." Michaud-Lariviere said he realised that energy had to come from somewhere, and that it must be able to be transferred into watts. The prototype has been "planted" at the telecom City Pleumeur-Bodou.

Making a simple Savonius wind turbine by Lance Turner There are many situations where you might need a small amount of electricity, for instance running gate openers, safety lights, water level indicators and other low-power devices. While solar would seem like the ideal solution, quite often this is not possible due to location and shading problems. Just such a situation arose when I decided to make our new gates automatic. New Silent Wind Tree Turbines Make Energy Production Beautiful Three years of research have led a team of French engineers to produce their interpretation of wind energy for urban locations. The Wind Tree stands at 26 feet tall, and its branches adorn the Pleumeur-Bodou commune in Brittany in northwestern France. Hit the jump to learn more about this new breed of silent wind turbine that turns energy production into an art form. Jérôme Michaud-Larivière, the founder of the company New Wind, says that “The idea came to me in a square where I saw the leaves tremble when there was not a breath of air.” He went on to hypothesize that the energy “had to come from somewhere and be translatable into watts.”

Home Made Wind Turbine Want to build a wind turbine for your home? I have gathered several PDFs for those who want to build there own wind turbines and have links to them at the bottom of this post. They cover all types of wind turbines and issues that you may run in to such as wind speeds and noise. From reading these my self I have found that the Hi-VAWT takes all into consideration and is easy to replicate. In VENTURI horizontal axis Wind Turbines wind turbines the blades rotate and describe a circular surface. Urbolienne, a new open source windmill in the city Urbolienne, the first urban open source micro wind turbine, could soon be the next big thing in domestic renewable energy. After off­shore wind farms and pro­pellers on peaks, why not tur­bines on build­ing rooftops ? The urban wind­mill could finally score some points in the do­mes­tic re­new­able energy race. Ur­boli­enne, a mi­cro-wind­mill pro­to­type de­vel­oped by the French con­sult­ing firm Aeroseed, gen­er­ates energy on sites where the wind is ir­reg­u­lar and often changes di­rec­tion, which is the case in the city. This in­no­va­tion could change every­thing. While solar energy has long since col­o­nized in­di­vid­ual houses, do­mes­tic wind­mills are often shunned because of their high cost, low ef­fi­ciency and ir­reg­u­lar energy output from random winds, which are all sys­tem­atic in urban zones.

Silent rooftop wind turbines could generate half of a household's energy needs Small wind turbines scaled to the right size for residential and urban areas have so far lived in the shadows of their larger wind-farm-sized counterparts. The power output has been too low for a reasonable return on investment through energy savings and the noise they produce is louder than most homeowners can deal with. A Dutch renewable energy start-up called The Archimedes is working to solve both of those problems in a new class of small-scale wind turbine -- one that is almost silent and is far more efficient at converting wind into energy. The company states that the Liam F1 turbine could generate 1,500 kWh of energy per year at wind speeds of 5m/s, enough to cover half of an average household's energy use. When used in combination with rooftop solar panels, a house could run off grid. "When there is wind you use the energy produced by the wind turbine; when the sun is shining you use the solar cells to produce the energy," The Archimedes CEO Richard Ruijtenbeek said.

Clarian Power: SmartBox Plug-In Wind Power The SmartBox Wind Turbine is a 48-inch tall vertical-axis wind turbine (VAWT) that plugs directly into an existing electrical outlet and automatically generates power whenever the wind is blowing. The SmartBox Wind Turbine can be mounted directly to the side of a home, on a rooftop or wind tower, or even existing street lights. And, it can generate up to 40 kWh per month in moderate winds enough to light an average home using energy efficient light bulbs. Expected to cost under $800, the SmartBox Wind Turbine is a cost-effective option for homeowners and small business owners looking to harness wind power for the first time. Working in tandem with the existing power grid, Working in tandem with the existing power grid, the SmartBox Wind Turbine works to conserve energy by producing enough clean, renewable wind power to offset a portion of the power being consumed in your home.

Build this open source DIY wind turbine for $30 Getting started with home wind energy projects can set you back a pretty penny if you buy a finished product, but if you're a little bit handy and don't mind scrounging for materials and getting creative in the garage or backyard, you can try your hand at building one of these DIY wind turbines for about $30 in materials. After all, it is #iheartrenewables week! We've previously covered Daniel Connell's open source concentrated solar collector plans, but now he's back with another great DIY renewable energy project, a vertical axis wind turbine based on the Lenz2 lift+drag design. Connell's design calls for using aluminum lithographic offset printing plates to catch the wind, which he says can be obtained cheaply (or possibly even free) from an offset printing company, and a variety of hardware and a bicycle wheel. "The turbine uses the ~40% mechanically efficient Lenz2 lift+drag design. Here's a little clip of the vertical axis wind turbine being challenged by strong winds:

Mag-Wind Vertical Axis Turbine for your Home UPDATE: It turns out that this product was a fraud, and the proponent of it has been indicted for securities and wire fraud. You can read more about this at Paul Gipe's website Wind Works. We get excited about new technologies; sometimes we jump the gun, so it is great to find a product that is new, different and actually available. It's a "Magnetically-Levitated Axial Flux Alternator with Programmable Variable Coil Resistance, Vertical Axis Wind Turbine' , and it has just come on the market. Designed by Thomas Priest-Brown and Jim Rowan in Canada and manufactured in Texas, it"solves 11 different problems that previously limited the development of vertical-axis wind turbines for generation of electricity ." The center hub floats on a magnet, and the coils that generate the power are at the outer ring, with magnets at the tips of the blades flying over them at high speed.
