  1. Wind Farming

  2. Windmill History • Windmills have been in use since 7th century Persia • Initially employed for grinding flour and pumping water • Pioneers such as James Blyth (18??-18??) developed and patented a dynamo version in 1887 which powered the lights in his cottage Early Persian Windmill ‘Windmill at WijkbijDuurstede’ - Jacob Isaakszoon van Ruisdael, Wind-turbine advertisement

  3. Wind Turbine Design Energy Output • Wind turbines use kinetic energy from the motion of air • Energy flowing through an imaginary area is calculated as • While mill output varies considerably, a general rule is the larger the blade the more energy output p = density of air v = wind speed Avtp = mass m per unit time E= mv2= (Avtp)v2= Atpv3 1 1 1 E 1 2 2 2 t 2 P= = Apv3
