In nature, air flow is created through temperature differences; the greater the difference, the stronger the air flow. If a large enough temperature difference can be accessed through design, then the air flow created could power or enhance a windmill or turbine.

The color black is used to absorb the heat from the sun. Solar ovens routinely reach temperatures of over 300° F. The temperature of the earth a few feet down remains about two to three degrees higher than the mean annual air temperature. I believe there may be a way to use this temperature difference to create a strong air flow as shown in the diagram below.

A water source near the input may be able to help achieve a lower input temperature.
