The Wind Energy Industry is Nothing New

Chinese Windmill Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an important source of energy. Here are a few quotes that were recorded in the past, which prove that wind was always important in generating energy. View Comments

A Rose Wind Turbine by Any Other Name…

Rose Wind Turbine The one knock on wind energy is that it is not portable. Until recently, there were few if any portable devices that were available to literally take wind power on the go. That is changing quick as there are several “back-pack” style devices that are on the market. The Rose Wind Turbine is the latest invention to be introduced to this ever growing energy niche. The Rose Wind Turbine is a small portable device that is small enough to fit into the trunk of the car and barely be noticed. However, once this portable wind turbine comes out, it is sure to turn heads. View Comments

Jet Engines the Inspiration for New Wind Power Technology

Jet Engines Wind Power Wind power has recently received a nice boost as one of the hottest forms of energy on the market. When comparing the recent market growth against all forms of energy, both renawables and non-renewables, wind turbines seem to be jumping to the head of the pack. While it still has a way to go before it catches up to solar, it is gaining ground rather quickly. Something that will help pick up the pace even further is new technology that is coming from FloDesign. Their truly unique wind turbine is actually based on the design of a jet engine instead of the traditional windmills that we see all across the country. Their concept seems to be a simple one, but it extremely effective. View Comments

Is It Possible To Convert To 100% Wind Power?

Wind Power With all the talk of going green, the question had been thrown out many times if there will ever be a time that we can use nothing but renewable energy to power our world. A small island in Denmark is trying answer that question with a resounding yes as they power up every single day via nothing but wind power. The Danish island is the ideal setting as the wind literally never stops blowing. The North Sea offers the perfect opportunity to capitalize on the winds that come off of the sea and for them to use wind power as their primary source of power. As a matter of fact, the wind power that they are using is their ONLY source of power. View Comments

The Kite Wind Generator

Kite Wind Generator It's an expert estimation that the total energy stored in wind is 100 times higher than actually needed by humans on this earth. The catch is that we have to learn and devise ways to trap this wind power blowing across the planet earth. Experts tell us one more thing that most of the wind energy is available at high altitude and we can’t manufacture turbines of that height. So we have to think of new ways to trap that wind power blowing at a significant height. Some experts estimate that the total energy contained in wind is 100 times the amount needed by everyone on the planet. However, most of this energy is at high altitudes, far beyond the reach of any wind turbine. View Comments

Small, Low Speed Wind Turbine

Low Speed Wind Turbine Most of us want to reduce our carbon footprints but currently most of the alternative energy products are simply unavailable for urban population that lives in metros. But gradually the scenario of alternative energy is changing and manufacturers have started thinking from common person’s point of view. Recently EarthTronics, which is based in Muskegon, Michigan, has developed a wind turbine that can be used by individual homes. EarthTronics also claims that it can operate at speeds as low as 2 miles an hour. Consequently, homeowners this fall will be able to buy a wind turbine at hardware stores that tackles the small wind industry's bete noire: slow wind. This turbine is named as Honeywell Wind Turbine and it will be distributed through Ace Hardware stores in the U.S. It will be sold for $4,500. WindTronics developed the turbine and licensed the technology to buildings systems giant Honeywell. View Comments

Using Existing Infrastructure for Wind Turbines

Wind-it The Metropolis Magazine has been holding Next Generation Design Competition since 2003. They want to provide a platform for young designers to promote the spirit of activism, social involvement, and entrepreneurship. They offer prize money of $ 10,000. But the real attraction is the publicity given to the projects of winners and runners-up. This recognition helps abstract ideas take concrete forms. For 2009, the theme for the Next Generation Design Competition was: How do we fix our energy addiction? They offered some guidelines, "Think about how we live and work, what we use, how we get where we need to go, hidden costs to our pocket books and the environment, across the whole design spectrum. Focus on one area that needs fixing—products, interiors, buildings and landscape, communication systems, or anything else you can imagine—and develop your idea fully. And above all, think of our energy addiction as a design problem at all scales." View Comments

WindCube Generates Electricity in Moderate Wind

WindCube Wind power is the fastest growing industry in the alternative energy sector. Wind turbines generate clean and green power for us but they have certain precondition. One of it is the power unit has to be set up in strong wind area. But Green Energy Technologies has developed a brand new wind power generator known as the WindCube. It is smaller compared to the normal wind generator. WindCube is specially designed to set up on the roof of a building in urban and rural areas. WindCube carries a 22 x 22 x 12 feet framework and its single unit can produce a maximum of 60kW of power. Mark L. Cironi, who is the president and founder of Green Energy Technologies, explains, "Building owners anywhere can consider being a part of the renewable energy picture. With WindCube, it’s not necessary to have the wind of Kansas or Nebraska to become a generator of wind power. In states with excellent renewable energy incentives, moderate wind and high electric rates, the payback can be as little as three years." View Comments
