Catching wind to rotate a load

[lauram]

Hi there,

I am trying to design a rotary airer that spins better than the current ones. I am wondering if it is possible for a design such as the one attached to be able to catch enough wind to spin a load of about 10kg?

Apologies for the sketch quality. Any advice would be greatly appreciated.

Thanks,
Laura

Sure, one could design a wind vane to spin a 10Kg load....
