Vertical Axis Wind Turbine (VAWT) Designs
There are a number of vertical axis wind turbine (VAWT) videos and designs or plans, on the internet. We have sorted through quite a few and will present here, some of the better plans for the do it yourself (diy) handyman who is interested in building their own turbine.
If you are more inclined to purchase off the shelf, keep in mind our comments regarding the total power you can expect to achieve at your home. As a general rule of tumb, most household sized wind turbines, will produce an “average” of one tenth of their rated output. …
Wind energy fans welcome Sarkozy plans but question timing Date: 27-01-2011
France announced this Tuesday (25 January) tenders for a 10 billion offshore wind project that will create 600 wind turbines capable of churning out 3,000 MW of energy. But environmentalists warn that more still needs to be done to meet the country’s and the EU’s 2020 targets.The project was announced by President …
… online, (under $50), it will be immediately available for download. Along with the detailed plans, blueprints and clear and concise manual, you will get your hands on easy to follow supplementary videos.
With this renewable energy package, you will be able to switch to homemade wind AND solar powered electricity, or a mixture of both, at the same time as maintaining the integrity of the product and keeping the cost to its minimum. You see, the components to build the wind turbines and solar panels will be available to you in your area – the DIY store, hardware store or you may even have some components around your house or in your garage.
Fresh off the heels of China’s wind announcement, an American power company has just announced that it will be building a 51-megawatt wind farm in eastern Colorado — east of the famed Rockies.
The plant will be built by Duke Energy of North Carolina. The company said in a press release today:
Duke Energy will develop the 51-megawatt (MW) Kit Carson Windpower Project on approximately 6,000 acres of land under long-term lease near Burlington, Colo. The project …
… significant energy requirement such as manufacturing facilities, hospitals, data centres etc. WED plans to invest approximately €100m in total over the next three years.
The company’s innovative offering allows its customers to lock in their energy costs at current levels for 5, 10, or 15 years, breaking the link with energy inflation. In addition, each MW installed reduces carbon emissions by up to 1500 tonnes of CO2 per annum allowing the host company to play its part in climate commitments, all without any capital outlay on their part WED will construct, own and operate the turbines.
Announcing the funding, Michael Aherne of ESB Novusmodus said: “WED will …
Bejing’s emphasis on saving energy reflects concerns about national security and the effects of high fuel costs on inflation, China’s export competitiveness and the country’s pollution problems.
Any energy policy moves by Beijing hold global implications, given that China is the world’s biggest consumer of energy and largest emitter of greenhouse gases. And even the new efficiency goals assume that China’s overall energy consumption will grow, to meet the needs of the nation’s 1.3 billion people and its rapidly expanding economy.
As a …
… tallest vertical-axis wind turbine, in Cap-Chat, Quebec
Vertical-axis wind turbines (VAWT) are a type of wind turbine where the main rotor shaft runs vertically. Among the advantages of this arrangement are that generators and gearboxes can be placed close to the ground, and that VAWT do not need to be pointed into the wind. Major drawbacks for the early designs (savonius, darrieus, giromill and cycloturbine) included the pulsatory torque that can be produced during each revolution and the huge bending moments on the blades. Later designs like turby, quietrevolution and aerotecture solved the torque issue by using the helical twist of the blades, similar to Gorlov’s water …
… first two are horizontal axis wind turbines (HAWT) and the third is a vertical axis wind turbine (VAWT).
The following parameters will be used for comparison purposes:
- Wind conditions: 7m/s at 50m, which is Class 3 wind regime
- Operations and maintenance costs: 1c per kWh of energy produced
- Annual sinking fund for repairs: 0.75% of total installed cost
- 3% inflation in costs
- Wind shear of 0.15; this is used to compute wind speed at hub height while assuming wind speed of 7m/s at 50m
- Life of wind project: 20 years
- Annual Energy Production (AEP) is computed based on power curves provided by …
