Check out the Gossamer series of Hampton Bay fans. They are designed to
be super energy efficient, which means that they have: 1) shaped blades
like one finds in an aircraft propeller providing >40% more airflow at
the same wattage 2) a remote control and a motion sensor that can be
programmed to turn off the fan after a certain amount of time without
activity in the room.
Bottom line: it's designed as a fan should have been designed in the
first place. Check it out at the Florida Solar Energy Center (part of
Florida State, I believe):http://tinyurl.com/b4byh
Available only at Home Depot and, alas, not in sizes less than 52".
Hence, I'm now looking at a StratoJet at http://www.airstrata.com/ and
trying to figure out how to hook up a remote control to it...
