I have seen a high wind turbine.it rotates by wind and produce electricity. How electricity is produced by such a slow movement of wings?the dynmo which produce electricity must be rotated at high speed, how it works to produce electricity? secondly,when there is no wind, wouldn’t it stop electricity production??
In: Engineering
Slow rotation is sped up with gears. A quick search for step-up gearing should easily demonstrate the concept. And yes, electricity stops being generated when the wind stops and the blades slow down. This is inconvenient, since it means that you have to be able to store the electricity for when it is needed, or use a different power system when the wind stops.
