According to the Global Wind Energy Council, global windpower capacity has been rising by at least 20% annually since 2000. Modern wind turbines produce 200n× more power than equivalent turbines of two decades ago. Today, there are more than 50,000 MW of installed wind-power capacity around the world, up from only 17,000 MW a decade ago. The world, you might say, is becoming a big fan of wind energy.
Water mills come to us from antiquity, but windmills do not. Wind has been used as the motive power for boats for millennia. This application uses only the pressure of the wind on a sail, and the techniques for controlling it were highly developed. It does not require machinery, except for the minor machinery for handling rigging. In this article, we consider only the use of the wind in producing mechanical power. The basic theory of turbines, of which fans and windmills are examples, is given in Turbines.
In 1745 Edmund Lee invented the fantail, or fly, a small windmill with an axis perpendicular to the windshaft. If the wind had a component from the side, the rotation of this wheel drove machinery that rotated the cap accordingly. In this way the mill was automatically kept facing the wind. The fantail was widely adopted in England and on the Continent, except, curiously, for the Netherlands, where the braced tail pole was retained.
The Bowens Jet Stream Wind Machine is a must for the fashion and beauty studio where creating movement in hair and clothes is essential. The Jet Stream's 2500 rpm fan gives all the breeze you need. The Jet Stream, with it's continuously variable speed motor and 20' (6 m) remote wire control, is equally useful for table tops where it's fine control can make adjustment for even the most delicate need. This 120VAC Jetstream can be suspended from a Hi-Glide, or other rail suspension system.
