| Fan Wheels??
I have heard mention of these recently and am curious as to how they work. We all know how a normal fan works, and the idea might seem to apply to the roadwheels of a car. But the wheel is moving sideways to the air that it is trying to pump. I presume the spokes of the wheels are intended to act as fan blades. If this is the case I could see it working if the wheel was turning in air that was still, but when the car is moving then each spoke is moving at the same speed as each piece of air it encounters. Isn't it? Anyway, I look forward to reading an explaination.
