you know how wind turbines go from thicker to thinner each arm, well it should go like a hammer instead from thinner to thicker, i think the reason why they made it the way it is is for aesthetic reasons....If it look like a hammer kind of think it will rotate faster but i am not sure check it yourself...Remember what makes the win turbine rotate is the BASE of the arm not the tip of the arm...

If the base is lighter it will rotate more frequently...This is what i think....The tip of the arm is lighter but the base is heavier you can blow all you want apply spin force all you want if the base of the win turbine fan is heavier it will rotate slower...Plus in a hammer type of arm design the heaviness of the tip will push it down like a pendulum along with the preceeding heaviness of the preceeding arm hammer heavier tip along with the preceeding and so fort plus the base of the arm is lighter which will mean the wind will make the base spin faster....Again it should AT LEAST, TRIPLE the ENERGY PRODUCTION OF EACH WIND TURBINE...AT LEAST...

Remember is the base that gives movement that rev up the whole fan turbine not the other way around...The way it is right now is like having a supercar with heavy rims, it will slow down the car...I think the reason they are the way they are now is to make the fan/arm, wind-conductive...

JUST REMEMBER, you can SPIN ALL YOU WANT, APPLY THE MOST FORCE IF YOU WANT IF THE BASE OF THE FAN IS HEAVIER: 20% FORCE APPLIED = 2% MOVEMENT/ENERGY...

Again a car can have the fasters engine, if the rims are heavier or like bricks: 50% force = 2% movement/energy....

the arms of the wind turbines have to look like a: Cricket bat....

Can someone please email this to every country in the world and the white house for i am very busy....

also, 1 wind turbine in a mountain should produce 7x more energy what 1 wind turbine on the ground produces, becareful is even more....Like with helicopters...The wind blows much faster with each passing altitude...and with the arms of a Cricket bat it should produce who knows: 13x more energy....
