The Tech That Could Fix One of Wind Power's Biggest Problems. For the cost of an iPhone, you can now buy a wind turbine that can power an entire house for lifetime. Indian startup Avant Garde Innovations has developed a low-cost wind turbine that can generate 3-5 kW hours of electricity daily By Sainul Abudheen K Soon after assuming office, Kerala (southern state of India) Chief Minister Pinarayi Vijayan kicked up a storm by publicly supporting the Athirappilly hydro electric project, which environmentalists said, if implemented, would create ecologic imbalance in the area and destroy the Athirappilly waterfalls, the largest natural waterfalls in the state.

It is not that the government is oblivious to the impact that the project could make, but it says it has no option but to leverage existing means to check the growing power crisis in Kerala, which partially depends on the private sector for electricity. Things are no different in other states either. While Kerala has attained almost 100 per cent electrical coverage, many parts of India still remain in the dark.

Enter two siblings who want to make India’s energy crisis a thing of the past. Comments. Résultats Google Recherche d'images correspondant à. Google Image Result for.

Turbinas eolicas residenciais. Philippe Starck lança turbina eólica residencial e promete mudar o mercado — EcoDesenvolvimento.org: Sustentabilidade, Meio Ambiente, Economia, Sociedade e Mudanças Climáticas. Utilizar as habilidades e ferramentas disponíveis ao seu redor para tornar o mundo mais sustentável.

Foi isso que o designer Philippe Starck decidiu fazer. Apos ganhar notoriedade em todo o mundo por desenhar produtos que ele mesmo julgava “desnecessários”, ele começou a unir design funcional e sustentabilidade. Sua última criação foi apresentada no dia 27/01 e exibiu uma turbina eólica residencial que será comercializada em breve a preços acessíveis. Durante a apresentação do Revolutionair, Starck afirmou que essa se trata de uma revolução no uso doméstico de energias alternativas.

Com formato retangular e potência para gerar até 1.600 kWh por ano, o produto poderá ser instalado em jardins, quintais e telhados e abastecer casas e pequenas empresas com eletricidade limpa. “Nós precisamos ajudar as pessoas a gerar sua própria energia, a fazer parte da luta”, defendeu o designer. Revolutionair O designer anunciou que serão fabricados dois modelos das turbinas. Mudança de comportamento. RidgeBlade wind turbine from the Power Collective Limited.

Eolo, el primer coche eólico 100 % colombiano. Utilizar el viento como fuente de energía es ya habitual en nuestra sociedad actual, cuya gran finalidad es sustituir a los combustibles fósiles. La Corporación Industrial Minuto de Dios, así como los diseñadores del proyecto EOLO y su inventor Javier Roldán, están desarrollando un prototipo de coche eléctrico con un sistema eólico integrado que le permite recargar la batería mientras está circulando. Un desarrollo que puede marcar el futuro de los vehículos eléctricos de bajo costo en Colombia. La aventura comenzó allá por el año 2008, cuando el inventor Javier Roldán fundó una empresa para comercializar partes de bicicletas para BMX, su deporte favorita y del que disfruta en su tiempo libre. Los beneficios obtenidos los invirtió en sistema de generación eléctrica caseros. Así llegó, tras varios prototipos y mejoras en el diseño, a construir un sistema eólico sencillo, funcional y eficiente para coches eléctricos. El prototipo pesa una tonelada y 5 velocidades.

Web: eolomotors.com. We Can Use Cell-Phone Towers to Forecast Wind Power. Photos: Onsemble/Flickr, CC.Goal: Accurate Wind ForecastsThe more wind farms we build, the more our power grid will have to incorporate mechanisms to deal with the inherent variability of a wind farm's output. Part of that will probably be accomplished by having more long-distance transmission capacity and interconnecting regional grids, another part might come from demand response and real-time pricing, and being able to accurately forecast how much wind there will be hour by hour will also help to optimally use wind resources.

This is the problem that wind data provider Onsemble is working on. Photo: Flickr, CC The company says that it now has sensors capable of tracking the wind data near 95 percent of the wind farms in Texas, and that its data is very accurate because it has put its sensors on cell phone towers (80-120 meters above the ground, unlike the ground-level stations used in most cases). Nuevo tipo de molino de viento produce energía limpia, biogás y agua potable - PDM Productos Digitales Móviles. El EWICON no es solo una turbina completamente limpia; además este reinventado molino de viento es capaz de obtener biogás o incluso agua potable. Aún siendo solo un prototipo, esta reinvención del molino no solo obtiene energía limpia de una forma completamente original, sino que es capaz de reciclar y obtener el agua de lluvia o incluso producir biogás.

Y todo en un edificio que parece de película y que contendría restaurantes, casas y comercios entre sus estilizadas paredes. El EWICON, según sus creadores, podría convertirse en uno de los nuevos iconos de los países bajos. Este remodelado molino está diseñado para satisfacer todas las necesidades de sus habitantes de una manera completamente ecológica, respetando al máximo el medio ambiente.

Porque, efectivamente, hablamos de un enorme edificio, no solo de una planta de producción, integrado en la estructura. Ésta consiste en una turbina que utiliza la diferencia de cargas de las gotas de agua para producir energía. Fuente: Hipertextual. How it Works | Sheerwind. Watch this: Watch 3 actual turbines in action! SheerWind’s INVELOX Wind Delivery is simply a better way to harvest wind energy.

Wind is captured at the top of the funnel shaped INVELOX system. The omnidirectional intake area allows wind collection from any directionWind is funneled through the systemWind is concentrated and further accelerated in the Venturi Effect* section of the INVELOX system. *The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase.Wind is delivered to the turbine/generators to convert the accelerated wind to electrical power. INVELOX is the first single wind tower capable of powering multiple turbines in a row or seriesDiffuser returns wind to nature This system of capturing, concentrating, accelerating, and harvesting wind power in a funnel is a patented system we call INVELOX™ (for INcreased VELocity).

CHASING THE WILD DRAGON: Microwave wind generator. This is a lesson on recycling. Everything here was built from scrap microwave ovens with the exception of the bearings and pivot mount also the plywood. Microwave ovens have an abundant source for the materials used in making an alternator and the rest of the components of an actual working wind generator. They contain large 2 1/4" round magnets ( 2 in each unit - in the magnetron ) plenty of sheet metal ( cases ) and even useful wire in the transformer. You could actually use the transformer metal as the stator laminates. WARNING: Microwave ovens utilize very high voltage to drive the magnatron unit. This will probably dry up my source for microwaves but you can call any appliance repair and find many microwaves free for the asking. I started out by cutting an 10" disc out of plywood, cut strips of steel out of the case to make the laminates.

Below are the beginning shots of the process... There is 60 feet of 3/4" steel in this stator. 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. The Liam's blades are shaped like a Nautilus shell.

“Generally speaking, there is a difference in pressure in front and behind of the rotor blades of a windmill. 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. That's not really a problem. No electricity equals no light pollution. 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. . Make Your Own Miniature Wind Turbine. Renewable energy is the wind beneath our turbine blades. Over the past few years, wind power has been among the fastest growing sources of energy in the world. Learn how to capture the airstream's gusting force with this rugged PVC turbine design by Michael Arquin, founder of the KidWind Project. This exploratory project teaches engineering and modeling and—to make it age- and skill-appropriate—can be scaled up or down in complexity to create more or less electricity, as well as to demonstrate concepts such as energy transformation and blade efficiencies.

New wind turbine looks like a tree, generates power silently. Wind turbines used for power generation work best when they’re large and mounted up high where wind speed is higher. This is not an aesthetically appealing proposition, but it’s the only way wind power makes sense on the large scale right now. A French company is trying to change that with a contraption called the Wind Tree.

As you might guess, it’s an array of wind power turbines in the shape of a tree, and several of them will be deployed in Paris this coming March as a test. The Wind Tree is being developed by NewWind and has 72 artificial leaves. Each one is a vertical axis turbine, vaguely conical in shape. Because each one has little mass, they can generate power with a gentle breeze as slow as 2 meters per second (4.4 mph). At 11 m (36 ft) tall and 8 m (26 ft) in diameter, the Wind Tree is about the size and shape of a real tree, and images of the prototype actually do look rather nice. Sleek Wooden Wind Turbine Is an Antidote to NIMBYism. © Michael Kopp There are a lot of wild wind turbines out there, from the inflatable, high altitude variety to those inspired by bumblebee wings. This design is also innovative, but really stands out for its sleek wooden blades, which should appeal to those who are put off by the unappealing traditional wind turbine.

Enessere, an Italian clean technology company, calls the turbine the Hercules, despite its slim, almost dainty look. Designed by Terry Glenn Phipps, the vertical axis setup can take advantage of wind coming from any direction, so the entire mechanism doesn't have to reorient to adapt to shifting weather conditions. The three wooden blades each measure three meters long and weigh about 15.5 pounds. The Hercules generates 3kW, just a fraction of a large turbine's output. But, with its focus on design and aesthetics, the Hercules is not made for commercial applications.
