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. 11 Comments

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. 14 Comments

Renewable energy is one of the hottest things on the market right now but until recently, solar power has been getting most of the attention. While there are plenty of techno gadgets, like solar briefcases and solar laptop chargers, that can have solar power on the run, very few if any items exist for other sources of renewable energy to become portable. The foldable wind generator has all the right ideas, but may still be just a bit ahead of its time. 6 Comments

Researchers at the Cornell University have taken inspiration from nature and tried to imitate the swaying of tree branches. So what is the difference between natural swaying of trees and energy-harvesting tree created by Cornell University researchers? The flapping leaves developed in the laboratory generate energy which can be utilized by us. They are christened as the “Piezo-tree.” The synthetic leaves of the “Piezo-tree” are connected to a piezoelectric stem. The whole exercise till now appears to be low-cost, and easily scalable. 10 Comments

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. 5 Comments

Of the total amount of electricity generated by all sources, about 75% is used by buildings, a major fraction of which is consumed by air conditioners. With the demand of renewable energy increasing with every passing day, inventors are trying to find the best possible means to store the generated energy during the best time, to provide power when the generators aren’t getting the resources they need. It is a natural phenomenon that the wind blows stronger at night than in the day. We don’t need that extra energy during nighttime. We can store this energy and use it during daytime when the load is too much on the grid. 3 Comments

When people thought about telephones in underdeveloped countries it was like they would have to invest a huge sum in infrastructure in the form of poles, wires and equipments. No one imagined about cell phones at that time. They transcend most of the infrastructures. In this hour of impending depletion of fossil fuels we have to think differently. The steps may seem small today but they might leave a huge impact in future. Today we can’t be a bystander and watch the energy scene passively. 14 Comments

GE, the US industrial group, is promoting and showing confidence in offshore wind technology by buying ScanWind, which makes direct-drive turbine components. This move will help in generating thousands of new jobs in the field of designing and manufacturing turbines. This move will affirm the confidence of investors in the fledgling offshore wind industry, which has been weighed down by concerns about costs and reliability. GE is moving ahead with establishing turbine manufacturing facilities to serve the European markets at first. They have to make up their mind about the size of the investment and location. 12 Comments

Off shore wind is steady and blows harder. If a country is densely populated it is hard to find open space to install wind farms. That is why there are more and more offshore wind farms in densely populated Europe where there is limited space on land and relatively large offshore areas with shallow water. Scientists of the Geesthacht GKSS Research Centre are interested in offshore winds and mechanics of sea waves. They are working on a radar system to study the behavior of the sea waves. This technology will be available for utilization on the North Sea on the FINO3 research platform. This technology will help in finding out the details of the interactions between offshore wind power machines and swells. 1 Comment

Some of the African regions are so hot that unless you're are accustomed to that climate it is not possible for your to survive. Extreme temperatures also generate extreme winds and perhaps this is the reason wind farms have great potential in Africa. Some 365 giant wind turbines will be installed in desert around Lake Turkana in northern Kenya to create the biggest wind farm in Africa. Once completed -- tentatively in 2012 -- the £533m project, backed by the African Development Bank, will have a capacity of 300MW, a quarter of Kenya's current installed power and one of the highest proportions of wind energy to be fed in a national grid anywhere in the world. 9 Comments

Wind energy is undoubtedly one of the cleanest forms of producing power from a renewable source. There is no pollution, there is no burning of fossil fuels, and unless something very drastic happens, you don’t run out of wind. But it’s not like you can erect a wind turbine anywhere and it will start generating power for you. There are lots of factors that can make an impact on the amount of energy you can generate out of wind. 14 Comments

Now we know that oil reserves are not going to last forever we are searching for alternative energy resources keenly. We are reading about new ways to tap energy from renewable resources. Sometimes these alternative energy resources seem quite odd and impractical. But we never know how they will shape up in future or how they will perform in future. Imagine New York being lit up by high-flying kites in the sky! These kites are supposed to utilize the wind power of New York. 11 Comments

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. 17 Comments

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." 22 Comments

People are trying various sources to produce alternative energy. We have often witnessed children flying kites. But very few of us have given a thought to generate energy from kites. Scientists from Delft University of Technology in the Netherlands produced energy from the wind by flying a 10-sq metre kite that is attached to a generator. It generated 10 kilowatts of power. This energy was enough to meet the power needs of 10 family houses. Scientists are now aiming for a 50kW version of their invention. They have named it Laddermill. Their ultimate aim is to go for a version of multiple kites. They will be able to produce 100 megawatts of power that could meet up the energy requirements of 100,000 homes. In order to generate power the kite pulls a string attached to the generators on the ground. Upon reaching their maximum height, they are reeled back down to repeat the process. 10 Comments

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." 41 Comments

These days many companies are exhibiting awareness about clean and green energy and trying to use that technology for reducing costs too. Recently Minneapolis-St. Paul International Airport has set up ten wind-powered electricity generators. They are using the energy to power an electric utility vehicle. We are acquainted with the fact that airports are windy places. So a knowledgeable management can utilize this air power and boost its environmental credentials too. They have installed ten 1 kW Aerovironment wind turbines on top of the airport fire station to harness the power of prevailing northwest winds. The turbines are expected to generate 10 kilowatts of electricity an hour. They are powering their fully-electric Cushman Motors e-Ride exv2 utility vehicle with the energy generated by these turbines. Their utility vehicle has a range of 45-55 miles and costs around $200 a year to run. 3 Comments

Sources of alternative energy are still in infancy stage and taking nascent steps towards the future. So there are ample scopes for scientists to improve upon the various aspects of existing models of alternative sources of energy. There is so much untapped, and so much to explore in this sector. That’s why we are daily flooded with information in the alternative energy field. But sometimes we hear about the improvement in the existing models itself. Researchers from the University of Alcala (UAH) and the Complutense University in Madrid (UCM) have devised a new method for predicting the wind speed of wind farm aerogenerators. 9 Comments

We all know about the impending future of the fossil fuels. Ultimately we will be forced to look for alternative energy fuels. Those countries who have resources and infrastructure are taking up these challenges very intelligently. Scientists and researchers know that existing alternative sources of energy can’t take up the challenges created by total exhaustion of fossil fuel. So they are continuously trying to better the existing technologies of the sources of alternative fuels. This time Leviathan Energy presents a technology for new and existing wind farms to produce more energy from a relatively small investment, a solution every manufacturer worth his/her salt wants i.e. more by investing less! 3 Comments

The new Peñascal wind farm in Texas hopes to become a model for responsible development by installing new radar technology to protect migratory birds and wildlife. According to recent studies, wind farms kill about 7,000 birds a year, although actual numbers are thought to be much higher. The new 202MW wind farm, operated by Spanish firm Iberdrola Renewables, uses radar technology developed by Florida based DeTect, Inc. 9 Comments
