Note, the "bladeless" fan does in fact have blades, but they are tucked away in the base. It is effectively sucking air into the base and pushing it along channels/tubs to be output around the trim of the ring. Maybe it has some use for underwater vehicles, such as an environmentally sensitive area (no exposed blades to hit sea creatures). But as Marc points out, it would come with an efficient hit. Cheers, Ian.
