Wind Turbines - Kinetic wind energy generator technology - 0 views

  • 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
  • Renewable energy production and demand growth is gaining momentum in many ways across the world. There is a booming demand of wind power today and all wind energy equipment manufacturers are gearing up to meet the demand and take advantage of it. Wind power capacity growth will be reaching 447GW in the next five years and by year 2014 end, Asia will lead the world in installed wind capacity.
  • Yes, the day is not far off when reaching for sky is the new motto for generating cost-effective renewable energy. Initially it was considered to be technically non-viable to tap high-altitude winds. But today, technically-advanced materials and innovative computer know-how are giving new life to this scheme with innovative autonomous aerial structures using wind energy to generate power

  • 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.
  • A research company in New Hampshire recently patented its bladeless wind turbine, which is based on a patent issued to Nikola Tesla in 1913. This wind turbine is christened as the Fuller Wind Turbine. This turbine is developed by Solar Aero. The specialty of Fuller Wind Turbine is it has only one rotating part, known as the turbine-driveshaft. The entire machinery is assembled inside a housing. Wind turbines are often disliked by environmentalists because they kill birds and bats and often generate noise for the residents living nearby
  • Presently Fluid Dynamics Expert, John Dabiri, is very much on the quest of improving designs of wind turbines. Spotting behaviours that may throw light on energy-related practices in biological system and trying to implement that in real-life situations is part of that quest and Mr.Dabiri is jubilant that he is learning lessons from a school of fish! Water-energy, and wind energy are both studied.
  • 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
  • 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."
  • 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

U.S. Takes Global Lead in Wind Energy Production | LiveScience - 1 views

  • During the first half of 2008, the United States, for the first time, generated more wind energy electricity than Germany, despite the fact that the smaller European country still has more turbines than we do. Germany has enough turbines to collect about 22,000 to 23,000 megawatts of power, while the United States has a capacity of about 18,000 megawatts,

How much CO2 does solar energy produce? | Ecooutfitters.net - 0 views

  • Let’s not hide the fact that manufacturing solar panels requires resources, fossil fuels that release CO2 emissions and add to our carbon footprint. However, it’s been shown in numerous studies that solar panel production releases nowhere near as much CO2 and other greenhouse gases as electric generated from coal, oil, natural gas, etc. (And you still need to produce the equipment to generate electricity from those sources as well.)

Solar power - Wikipedia, the free encyclopedia - 0 views

  • The Life-cycle greenhouse-gas emissions of solar power are in the range of 22 to 46  g/kWh depending on if solar thermal or solar PV is being analyzed, respectively. With this potentially being decreased to 15 g/kWh in the future.[71] For comparison (of weighted averages), a combined cycle gas-fired power plant emits some 400-599 g/kWh,
  •  
    Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.

Solar Power - Advantages and Disadvantages - Sustainable Development Information - 0 views

  • By converting the power of the sun into electricity, solar energy is clean, green, will never run out and, after the initial cost of the solar panels, is entirely free
  • The sun is constant – it will always be there and is therefore a reliable, utterly renewable source of energy.
  • As it does not rely on the burning of harmful fuels to generate electricity, solar power is non-polluting – it does not contribute to global warming or greenhouse gas emissions.

Science of Summer: How Do Ocean Waves Form? | LiveScience - 0 views

  • Presnell explained that wind speed and duration help in determining the size and frequency of ocean waves. Another factor is called "fetch," referring to the span of water over which a breeze blows, and the longer a fetch, the more energy a wave can build up.
