My question today is : Why Do Wind Turbines Have Three Blades?
I was watching online some tutorials an find 1 very interesting that explain how they get to us a 3 blade turbine to make energy.
Adding 1 blade may cost more then 100000 $ and in the end can not be more efficient.
Making a turbine whit 2 blades will speen faster but will make more noice and will be more fragile in high winds.
