When I was a kid, I read an article about an engine built like this from instructions found in American Scientific. The idea was the reverse of this. The rubber bands in the wheel were partially immersed in water at room temperature, and as the water evaporated in the air section, it became cooled by evaporation. As it continued to rotate, it was immersed in the room temperature water, and warmed back up to room temperature. So, it was an engine driven by evaporative cooling. Kinda cool.

The concept's been around forever. When I was a kid, (a hundred years ago), there used to be a bird that would dip its' beak in water. I haven't seen one in ages so I don't know if they're still available.
