New Bladeless Wind Turbine Claimed to be Twice as Efficient as Conventional Designs

New Bladeless Wind Turbine Claimed to be Twice as Efficient as Conventional Designs
© Saphon When it comes to the future of wind power, one company thinks it looks a lot different than you would expect, and cheaper and more efficient to boot. Saphon, out of Tunisia, is interested in finding partners to mass-produce and market their unique wind energy device, based on their own Zero Blade technology. "The Zero-Blade Technology is largely inspired from the sailboat and is likely to increase the efficiency of the current wind power conversion devices. The blades are replaced by a sail shaped body while both hub and gearbox are removed." SLIDESHOW Wind Energy Today: A Look at Wind Energy Projects Around The World According to the company, their zero-blade technology devices are capable of overcoming the Betz' limit, which states that no turbine can capture more than 59.3 percent of the kinetic energy of the wind.

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%.

Portable, collapsible wind turbine weighs less than 4 pounds It used to be that every week there was a new type of portable solar charging device to help you charge your gadgets on the go, but lately we've seen quite a few portable wind turbines, even DIY ones. This new wide range of devices to help you stay off grid whether you're using them in your backyard or on a long-distance hike is great because the more options that are out there, the better the chance is that people will use them and have an easy way of bringing renewable energy into their lives. The latest personal wind turbine offering is called WindPax and its inventors have taken to Kickstarter to raise money for its production. This one is neat because it has features I haven't seen in similar devices, especially its adaptability to different scenarios. There are two different sizes -- the Wisp and the Breeze. The Wisp collapses small enough to fit into a backpack, but can be assembled to reach 6 fit in height and has a 1 ft diameter.

Plan Bee: Feds Propose Plan to Reverse Honeybee, Butterfly Decline The federal government hopes to reverse America's declining honeybee and monarch butterfly populations by making more federal land bee-friendly, spending more money on research and considering the use of less pesticides. Scientists say bees — crucial to pollinate many crops — have been hurt by a combination of declining nutrition, mites, disease, and pesticides. The federal plan is an "all hands on deck" strategy that calls on everyone from federal bureaucrats to citizens to do what they can to save bees, which provide more than $15 billion in value to the U.S. economy, according to White House science adviser John Holdren. "Pollinators are struggling," Holdren said in a blog post, citing a new federal survey that found beekeepers lost more than 40 percent of their colonies last year, although they later recovered by dividing surviving hives. The plan calls for restoring 7 million acres of bee habitat in the next five years.

'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.

Generating Off-Grid Power: The Four Best Ways So, you've thought about whether or not living off the grid is right for you; you know that it means no more utility bills and generating all of your own power, but what's involved in that? It isn't as easy as slapping a few solar panels on the roof and calling it good; when it comes to generating off grid power, there are a handful of methods that can combine to generate all the energy you'll need to live comfortably off the grid.Plug in to off grid power with solar electricitySolar power is probably the one that jumps to mind for most of us when it comes to off-grid energy. The sun-powered option, which includes photovoltaic solar panels, an inverter and batteries, can provide lots of electric power (especially if you get a lot of solar exposure where you live) for a long time, without any moving parts and a little maintenance. When it comes to picking a turbine, size matters.

New Protein Supercharges Immune System to Fight Cancer by Orion Jones Scientists have discovered a new protein that appears to supercharge the body's own immune system, allowing it to compete against cancerous cells in ways that were previously impossible. Called LEM, or lymphocyte expansion molecule, the newly discovered protein molecule allows the immune system to continuously produce high quantities of T cells, which are the body's natural defense against cancer. "This is a completely unknown protein. 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.”

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:

Is Cohousing the Future? (Infographic) Is cohousing, the collaborative, intentional community of individual, private homes, the future of urban design? Compared to the isolated way some people live, and considering that over 50 percent of those in the United Kingdom don’t know their neighbors, this could seem like an extreme lifestyle change. However, those who are looking to pool their resources for convenience, community or consciousness see cohousing as one option for pursuing those goals. 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.
