There is an estimated 50 to 100 times more wind energy than plant biomass energy available on Earth.
Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines.
At the end of 2006, worldwide capacity of wind-powered generators was 73.9 gigawatts; although it currently produces just over 1% of world-wide electricity use, it accounts for approximately 20% of electricity production in Denmark, 9% in Spain, and 7% in Germany. Globally, wind power generation more than quadrupled between 2000 and 2006.
Until 2006 the wind energy industry was dominated by five countries which had a history of developing wind technology and manufacturing capability; Denmark, USA, Germany, Spain and India.
In 2006 China became significant and will be increasingly important in world markets in the future. 65% of the world’s wind power capacity was installed in Europe in 2006, compared with 69% in 2005, and 18% in North America compared with 17% in the previous year – Source GWEC
A second tier of wind energy countries has now emerged and seven have over 1,000 MW installed; Japan, Italy, United Kingdom, Portugal, France, Netherlands and Canada. Another two can now be included in this category because they have likely become eligible by mid 2007, these are Austria and Australia. – Source GWEC
But moves such as “Super-powered Magnetic Wind Turbine” are soon going to changes the above figures. Before I started working on this in blog 2 days back, it came in my mind that why not a massive structure as a wind turbine? and I came across “Super-powered Magnetic Wind Turbine”.
The way maglev wind turbine works:
- Magnetic levitation is an extremely efficient system for wind energy. Here’s how it works:
- The vertically oriented blades of the wind turbine are suspended in the air above the base of the machine, replacing the need for ball bearings.
- The turbine uses “full-permanent” magnets, not electromagnets — therefore, it does not require electricty to run.
- The full-permanent magnet system employs neodymium (”rare earth”) magnets and there is no energy loss through friction.
- This also helps reduce maintenance costs and increases the lifespan of the generator.
Advantages over conventional wind turbines:
They’re able to use winds with starting speeds as low as 1.5 meters per second (m/s).
They could operate in winds exceeding 40 m/s.
Currently, the largest conventional wind turbines in the world produce only five megawatts of power.
One large maglev wind turbine could generate one gigawatt of clean power, enough to supply energy to 750,000 homes.
It would also increase generation capacity by 20% over conventional wind turbines and decrease operational costs by 50%.
The maglev wind turbines will be operational for about 500 years!
- Construction began on the world’s largest production site for maglev wind turbines in central China on November 5, 2007. Zhongke Hengyuan Energy Technology has invested 400 million yuan in building this facility, which will produce maglev wind turbines with capacities ranging from 400 to 5,000 Watts.
- In the US, Arizona-based MagLev Wind Turbine Technologies will be manufacturing these turbines. Headed by long-time renewable energy researcher Ed Mazur, the company claims that it will be able to deliver clean power for less than one cent per kilowatt hour with this new technology.
- It also points out that building a single giant maglev wind turbine would reduce construction and maintenance costs and require much less land than hundreds of conventional turbines.
The estimated cost of building this colossal structure is $53 million.
