Wind Power Essay -- Wind Power Energy Sources Essays

trend tycoonHarnessing the natural personnel of the nobble is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years, principally for agricultural purposes. Basic windmills are ruling to have been used in Persia (now Iran) as early as the seventh century AD. Their ability to make use of otherwise untapped postcode sources without the needs and costs of other alternatives, ensured that they remained the machines of preference in several industries passim both agricultural and industrial revolutions. Whilst their staple fibre concepts have remained true to the staple fibre origins, technological advances have enabled engineers to adapt the mechanics of the mill to enable a more functional and useable source of power. In the 18th C, engineers developed spring sails (a device incorporating shutters onto the sails) to enable the mill to be phlebotomize at constant speed during variable wind speeds automatically. The development of the fantail in 1745 too ensured the mills ran in the face of the wind and along with airbrakes meant that the mill could run at its most efficient at all times without the riskiness of doing itself damage in strong winds. Uses developed into water pumping, wood sa elongation, papermaking, atmospheric pressure oil seeds and a variety of grinding uses.The use of wind turbines for generating electricity was pioneered in Denmark late in the 1890s. The concept was made a world by Poul la Cour (1846-1908) who had originally trained as a meteorologist. He built the worlds first electricity generating wind turbine in 1891 and although his project was a success, decided the sterling(prenominal) problem lay in storage of the electricity. As a result he used the electricity from his turbines for electrolysis in recount to produce hydrogen for the gas lighting in his school. One basic drawback of this scheme was the fact that he had to replace the windows of several school buildings n umerous times, as the hydrogen exploded due to small amounts of oxygen in the gas () DWTMA. As technological barriers were worked through, wind turbines became increasingly complicated. One of the greatest developments was the use of aerofoils instead of angled blades. Aerofoils have the benefit of using twinge to turn the blades in the same manner as an aircrafts wing rises on an air current. This type of blade replaced the older type, which relied upon drag, t... ...9, www.foe.co.uk capability without end, Michael Flood, Friends of the Earth, capital of the United Kingdom 1991Green Futures, Magazine of Forum for the Future, Issues 6 1997- issue 11 1998, capital of the United KingdomJohnston, Bryan, Landscape effects leave wind power up in the air, readiness 1084, 2.9.94.Milne, Roger, Renewables feel the draught, Planning no. 1095, 18.11.94.Microsoft Encarta 1996 Encyclopaedia, www.msn.comRothe, David, Renewable energy and rural development, Town and kingdom Planning, March 199 3.
