Project at a Glance Contents on the CD ROM
  • A windmill is a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades.
  • The first practical windmills had sails that rotated in a horizontal plane, around a vertical axis.
  • Windmills were in widespread use across the Middle East and Central Asia, and later spread to China and India from there.
  • The total number of wind powered mills in Europe is estimated to have been around 200,000 at its peak, compared to some 500,000 waterwheels.
  • A windmill used to generate electricity is commonly called a wind turbine.
  • A wind turbine consists of a rotor that has wing shaped blades attached to a hub; a nacelle that houses a drive train consisting of a gearbox, connecting shafts, support bearings, the generator, plus other machinery; a tower; and ground-mounted electrical equipment.
  • Wind machines and traditional ‘Dutch’ windmills preceded electricity supply and were used for grinding grain.
  • A cutting-edge technology in the field of thermoplastic composites has allowed us to create the strongest, lightest, and highest efficiency wind or
    water blades available in today’s market.
  • Aerodynamics is the science and study of the physical laws of the behavior of objects in an air flow and the forces that are produced by air flows.
  • Local mean wind speed is the most important parameter to consider in siting a windmill. Efficient windmills can produce 175 W per square meter of area swept by the propeller.
  • The site the windmill has to be placed has to be an area with a prevailing wind of at least 15 mph. the area has to be cleared of trees and other
    structures that block wind.
  • Other applications for small wind machines include water pumping, telecommunication power supply and irrigation.
  • Capital costs for windpower are high, but running costs are low and so access to initial funds, subsidies or low interest loans are an obvious
    advantage when considering a wind-electric system.
  • A large windmill (2 MW) needs an investment of 4 M € without subsidies.
  • In wind turbines we find two basic types of generators: asynchronous and synchronous generators.
  • The DOE/NREL scaling model is a spreadsheet-based tool that uses simple scaling relationships to project the cost of wind turbine components and subsystems for different sizes and configurations of components.
  • The worldwide annual wind power growth was 27%. The worldwide cumulative installed capacity is now 94,000 MW.
  • The North American market is the second largest in terms of total installed capacity and for the second year in a row, installed more wind generating capacity than any other country.
  • India was a latecomer to the global wind energy and wind turbine industry.
  • According to the Wind Energy Division of the National Aerospace Laboratories (NAL), nearly 40% of India's installed electricity capacity of over
    120,000 MW could be generated from wind energy.
  • The first modern wind turbine was developed in Denmark by Poul La Cour that experimented with classic windmill technology and electricity generation.
  • In Denmark, not only the private firms but also the universities have been in the forefront of technological frontier in development of wind turbines.
