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.-- gorn_the_great, Aug 05 2001 Ceiling Fan http://www.ceilingfan.comLOL very funny, rangelife [kelly23, Oct 04 2004] HVLS Fans http://www.avanti-c...ors.co.uk/fans.html [Worldgineer, Oct 04 2004, last modified Oct 21 2004] So this is just a ceiling fan as designed by TIm Allen?-- bookworm, Aug 05 2001 Hmmm...how about the blades and sound dampeners from a stealth helicopter? Oh wait. It's not the heat, it's the humidity anyways...-- Lucky_Setzer, Aug 05 2001 Groupie: "Far Out" Jimmy Page: "You mean like a spiralling vortex"? Quote from ancient memory: 'Hammer Of The Gods'-- thumbwax, Aug 05 2001 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.)-- angel, Aug 06 2001 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, Aug 06 2001 Starchaser: I don't see you point....-- CasaLoco, Aug 06 2001 "Ceilingwolf"-- The Military, Aug 07 2001 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.-- snarfyguy, Aug 07 2001 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.-- Monkfish, Aug 07 2001 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?-- StarChaser, Aug 11 2001 also hoping Marge isn't in the room-- rangelife, May 15 2003 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.-- Worldgineer, Jun 05 2003 A new business venue for Rotorway.-- pashute, Jul 15 2011 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.-- Alterother, Jul 17 2011 random, halfbakery
