Funny Looking Tower Generates 600% More Electrical Energy Than Traditional Wind Turbines The Sheerwind wind turbine promises to produce 6 times the electrical power than traditional wind turbines. This funny looking wind tower acts like a funnel, directing the wind from any angle, down through a tube to a ground based turbine generator. The funneling of the wind through a narrow passage effectively creates a “jet effect” increasing the velocity of the wind, while lowering the pressure. This is called the Venturi Effect. This speeds up the wind turbine mounted inside the narrowest portion and generates electricity. As such it can capture and generate electricity at a much lower wind speed than current wind power technologies. The idea is so simple, so elegant, and promises to produce so much more energy at lower cost and more efficiently, that it might just be the answer to many problems with current wind turbine technology. Imagine a smaller HOME version on your off grid cabin. Conventional wind turbines use massive turbine generator systems mounted on top of a tower.
A Material That Could Make Solar Power “Dirt Cheap” A new type of solar cell, made from a material that is dramatically cheaper to obtain and use than silicon, could generate as much power as today’s commodity solar cells. Although the potential of the material is just starting to be understood, it has caught the attention of the world’s leading solar researchers, and several companies are already working to commercialize it. Researchers developing the technology say that it could lead to solar panels that cost just 10 to 20 cents per watt. Solar panels now typically cost about 75 cents a watt, and the U.S. In the past, solar researchers have been divided into two camps in their pursuit of cheaper solar power. The new material may make it possible to get the best of both worlds—solar cells that are highly efficient but also cheap to make. One of the world’s top solar researchers, Martin Green of the University of New South Wales, Australia, says the rapid progress has been surprising. “Between 2009 and 2012 there was only one paper.
Tesla Technology: 5 Bladeless Turbines About To Revolutionize Energy Production Tesla Technology: 5 Bladeless Turbines About To Revolutionize Energy Production www.endalldisease.com “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 In 1913, Inventor Nikola Tesla patented a bladeless steam turbine that he claimed was the most efficient and the most simple rotary engine ever designed. Due to a lack of high-quality materials, Tesla was never able to properly build his engine. One century later, we now have all the materials needed to build Tesla’s turbine, and in 2010, a patent was issued to a company called Solar Aero for a wind turbine based on the Tesla design. Current wind turbine technology with rotating blades is both inefficient, and causes noise pollution, which has been reported to have detrimental health effects on residents living nearby.

World record solar cell with 44.7% efficiency The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record efficiency of 44.7% was measured at a concentration of 297 suns. This indicates that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. This is a major step towards reducing further the costs of solar electricity and continues to pave the way to the 50% efficiency roadmap. Back in May 2013, the German-French team of Fraunhofer ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin had already announced a solar cell with 43.6% efficiency.
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.

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. I reduced the project to just five little systems. for only $26. . Finally!
How Much Can You Save With Solar Panels? Just Ask Google If you’re considering solar power but aren’t quite sure it’s worth the expense, Google wants to point you in the right direction. Tapping its trove of satellite imagery and the latest in artificial intelligence, the company is offering a new online service that will instantly estimate how much you’ll save with a roof full of solar panels. On Monday, the company unveiled Project Sunroof, a tool that calculates your home’s solar power potential using the same high-resolution aerial photos Google Earth uses to map the planet. Click to Open Overlay Gallery The service is now available for homes in the San Francisco Bay Area, central California, and the greater Boston area. How Google Parses Your Roof Elkin’s own home has solar panels, and he once volunteered with Solarize Massachusetts to promote solar in the Bay State. As Google notes in a blog post announcing Project Sunroof, the time is ripe for such a tool. But Google’s service is a bit different. Go Back to Top.
Solar Panels Cost Guide | Prices and Calculator HOW TO CHART THE SUN’S MOTION IN RELATION TO YOUR HOMESTEAD Learn to track the sun before you design your home to determine the best orientation for it, as well as how to take advantage of the sun rays, because the position is also important for the passive cooling and heating of the house. Understanding the sun’s motion relative to a site is an important aspect of a good permaculture design, as various elements like plants, animals and solar devices depend on sun for their functionality. A good appreciation of the earth’s rotation about its axis, its revolution around the sun and the consequences of these motions on the sun’s position and availability at a given location on the earth’s surface, is essential for maximizing plant productivity, harnessing maximum energy, minimizing energy usage and maintaining a comfortable indoor environment for humans and animals alike. For a given site, if we can create a chart that shows the areas of year round shade and year round sunshine, one can plan and design the various elements for optimal functioning.
