Cost: In addition to friendly doormen, the building's management will also need to employ a pipe organist (hereafter referred to as a "doorganist").
Benefit: The entryway of your office or apartment building will bellow with your favorite organ riffs whenever you arrive or leave.-- swimswim, Feb 09 2010 Revolving door http://en.wikipedia...wiki/Revolving_doorDraught block [8th of 7, Feb 09 2010] Stack effect http://en.wikipedia.org/wiki/Stack_effectDriven by buoyancy [8th of 7, Feb 09 2010] Hallway Organ Hallway_20OrganEssentially the same idea. [phoenix, Feb 10 2010] Chicago would sound lovely.-- wagster, Feb 09 2010 About these "air pressure differentials"- please elucidate.-- csea, Feb 09 2010 I don't know the physics (or meteorology) behind the phenomena, but big buildings sometimes develop a lower air pressure inside than outside the building. You can see this when you open an exterior door and wind rushes in the door, sometimes making the door hard to open. The described device harnesses this wind for musical purposes.-- swimswim, Feb 09 2010 It's because of thermal gradients - the "chimney" or "stack" effect. It's also the reason revolving doors were invented.-- 8th of 7, Feb 09 2010 Quoth Wikipedia, "Revolving doors are also often seen as a mark of prestige and glamor for a building and its architecture". But, quoth I, so too shall the pipe doorgan be seen.-- swimswim, Feb 10 2010 "Good lord, man, why are you pulling the stops at random and throwing the sheet music around???"
"I'm a disorganist."-- MaxwellBuchanan, Feb 10 2010 //disorganist//
I am reminded of a couple of bad jokes about Beethoven "decomposing" and Newton &/or Leibniz "disintegrating".-- csea, Feb 13 2010 Why are Newton and Leibniz both named after biscuits?-- pocmloc, Feb 13 2010 Because they were christened so long ago. By the 20th century, all the good names were taken (Steven Hawking's parents considered naming him "Oreo," but decided it would be silly.)-- mouseposture, Feb 13 2010 random, halfbakery
