Oranfresh produces equipment for organge orchards--including frost protection wind turbines - The function of the wind machine is to mix the higher, warmer air of the inversion layer with the colder air surrounding the trees and the soil. Then it produces the downward movement of warmer air by forced convection, which results in a slight increase in temperature of the air below. www.oranmatic.com/Inglese/WindMachine.html
