"Windmill power is proportional to V cubed."

Nah. Look at #1375 a little closer.

It's simple, so drag =1 there. Air is compressible, so real drag is < 1.

Only supersonic shock waves have v³.

[John Jamieson]

Windmill power = K*airdensity*rotorarea*velocity^3.

I think you're referring to the energy as opposed to power.
