    I'm surprised the idea that the additional mixing of windmills over crops could offer some frost protection wasn't thought of earlier.

    I'm pretty sure this is just a case of people not paying attention outside their own narrow specialty. I thought it was well accepted practice for citrus growers to use huge fans to protect trees from frost.

    There is a big difference between a fan and a wind turbine. A fan makes the air move, but the wind is what makes the turbine move. It's hard to see what a turbine is going to do on a windless, frosty night.

    Not as far fetched as it might seems, often the frost is associated with a very shallow inversion meaning it above freezing only a few tens of meters above the ground and there's a breeze a few hundred meters up... Those wind turbine could delay the the formation of the inversion as long as even their top is penetrating above that inversion layer. I found an illustration that's above freezing but shows a pretty typical depth and range of temperature from a radiation inversion.
