Well by real world logic, i get a headwind twice a day when i commute to and from work.

So technically speaking they just drain the net from all the solar that's stored when it is sunny.

Let's hope that guy was just messing around and not actually that dumb as a lot of people seem to be nowadays.

On another note i jokingly called them fans last summer and thanked the local county for turning them on as it was pretty hot out.
