Pipe Doorgan
Use air pressure differentials in tall buildings to supply wind to pipe organs. | |
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.

Chicago would sound lovely. |

About these "air pressure differentials"- please elucidate. |
|
| |
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. |
|
| |
It's because of thermal gradients - the "chimney" or "stack" effect. It's also the reason revolving doors were invented. |
|

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. |

"Good lord, man, why are you pulling the stops at random
and throwing the sheet music around???" |
|
| |
I am reminded of a couple of bad jokes about Beethoven "decomposing" and Newton &/or Leibniz "disintegrating". |
|
| |
Why are Newton and Leibniz both named after biscuits? |
|
| |
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.) |
