[QUOTE="aussiefarmer, post: 647241, member: 5729"] The turbines erected in the last 3 years will spin in a frost , well before any breeze is at ground level, their efficient enough that power produced out ways the wear rate even in low winds. Some early turbines had an electric motor to start the rotation, the modern turbines simply roll the blades to get maximum effect and also do the same to control the speed limits. Each turbine has 4 electric motors uptop , one to roll each blade and one big one to turn the nacell (head) towards the wind. The most interesting bit is the blades actually pull the tower towards the wind like a boat propeller which keeps them upright in gale force winds. [/QUOTE]
