Install large helicopter engine on the ceiling with a suspended helicopter blade - and crank it up to full blast. This will thoroughly circulate and cool the air in any room no matter how stuffy or stagnant.

So this is just a ceiling fan as designed by TIm Allen?

Hmmm...how about the blades and sound dampeners from a stealth helicopter? Oh wait. It's not the heat, it's the humidity anyways...

This will also deafen anyone within thirty feet. (Most of the sound you hear from a helicopter is produced by the tail rotor; that's the one broadcasting horizontally. Given that that much sound is made by a relatively small rotor, imagine how much sound the main rotor produces.)

Not to mention the fact that a rotor blade that can blow downward with enough power to lift a many ton aircraft would flatten people to the floor.

StarChaser has a good point; it would have to come with a really big selection of paperweights, not to mention furnitureweights, peopleweights, etc. You'd most likely soon have a cyclone in your room.

When the weather is at its worst, retract the ceiling and fly to a more reasonable hemisphere. Put it in reverse to be rid of irritating houseguests. Chop vegetables for decadent-Rome-scale salads. All of these possibilities and still not a good idea.

CasaLoco: Consider that a helicopter's engine is powerful enough to lift a ten ton helicopter <Weight taken from a webpage, for the AH-6 Apache, 21,000 pounds> and move it at 180 mph, by blowing air downward.

Now, imagine that same airstream blowing downward in an enclosed room, instead of in free airspace.

See?

You do know you can never get the room cooler than the outdoor temperature this way, right? All a ceiling fan does is help sweat evaporate off your body, cooling you down a bit. Does remind me of high volume low speed fans though. I'll post a link if I can find it.

If we're going to go ahead and take this seriously, better to hang a hovercraft from the ceiling than half a helicopter. Better area coverage, no risk of decapitation, and you'll still get that desirable eardrum-fracturing effect. Let me know how that works out.
