Wind Power Posiblities

This is a short wind power historycopied from Vestas website with links.

Wind power through the ages
The ability to harness the wind and use its power for production has fascinated people for millennia, as this brief historical overview shows:
The wind on land, at sea and in the air
Man first learned to harness the wind as early as 4000 BC. The Chinese were the first to take to the seas in primitive rafts around this time.
It was a hot air balloon in 1783 that first lifted us from the ground, while in 1852 Henri Giffard designed the world’s first airship.
The world’s first flight in an engine plane took place in the USA in 1903. Two brothers, Orville and Wilbur Wright, succeeded in travelling 40 metres before landing safely again on the ground.
The history of the wind turbine
The first European wind turbines were built around 1100,and were used for both milling corn and pumping water.
In 1887-1888, American Charles F. Brush built the first wind turbine, producing current for 12 batteries, 350 filament lamps, two carbon arc lamps and three motors.
At the end of the 19th century, Poul la Cour built several experimental wind turbines and researched wind tunnels. Poul la Cour’s experimental turbine in Askov, Denmark, still exists today.
During the first half of the 20th century, wind turbines gradually faced increasing competition from coal-fired power plants and the nationwide power grid. However, shortages of coal and oil during the two world wars ensured that demand for wind power continued.
In 1957, Johannes Juul built the Gedser turbine which became the template for modern wind turbines. The Gedser turbine had a single generator and three revolving blades.
In 1979, Vestas sent the first wind turbines out to customers wishing to invest in renewable energy.
In 1980, the state of California decided that 10 per cent of its energy supply should come from wind power by 2000.
In the spring of 2004, Vestas merged with NEG Micon and became the undisputed world leader in the wind power industry.

So you can see windpower has a long proven history. You can use it to help cut your power bill in most parts of the country. We will be looking for more home sized wind turbines in this and future blog entries.

The qr5 turbine has been designed for use on or near buildings and requires a grid connection via a three phase electrical supply. The current model stands 5m tall without mast and costs around £38,000 installed. We are also developing a smaller model that is 2.5m high and better suited to most private residences as it will connect to the grid via a standard single phase supply. This model is now expected to come to market in 2009 due to an unprecedented commercial demand for the larger qr5.
If you would like to be kept informed on pricing and availability for the qr2.5 please use our contact form to register your interest.
If you already have or are installing and three phase supply and would like to get an idea on feasibility and costs for a qr5 on your site please complete our request a quote form.



GE Energy Reliable Performance, Cost-Effective Operation
With advanced wind turbines ranging from 1.5 to 3.6 MW, GE Infrastructure provides commercial wind turbines for both land-based and off-shore requirements. GE technology features robust designs for long, reliable performance, variable speed control and independent blade pitch for reduced loads and cost effective operation, and unique Wind Volt-Amp-Reactive ("WindVAR") electronics for local grid support and improved transmission efficiencies.

We will have more on this soon, let us know what you think in comments.

ATLANTA, Georgia (CNN) -- Larry Horsley loves that he doesn't buy much gas, even though he drives his '95 Chevy S-10 back and forth to work each day.

Larry Horsley's pickup has a set of neatly arranged electronics where his engine once was.
Horsley, a self-described do-it-yourselfer, simply plugs his truck into an electric wall outlet in his Douglasville, Georgia, garage and charges it overnight, instead of buying gasoline refined from mostly imported oil.
"If I can keep a dollar from going overseas, I'll spend two dollars," he said. The whole conversion, including the truck, cost him about $12,000, which parts dealers say is about standard.
