This came to me in a dream. Let me
preface this by acknowledging that current
ceiling fans circulate air throughout the
whole room.
Take a sphere (I’m thinking 1-2 feet
diameter) and seal it into two halves. Place
a fan in the center of the seal so it pumps
air from one half to the other.
Now mount
small air driven motors with small fan
blades on them as closely spaced as
possible. Air will be drawn in one side to
drive the motors on one half, and out the
other to drive the motors on that half. Fan
blades will be angled so that air emanates
out from the orb.
This is probably (definitely) less efficient
than existing fans, but aesthetically much
cooler (no pun intended) I think. Internal
lighting on the sphere would add even
more aesthetic value.

So kinda like a disco-ball, but with air blowing out the holes instead of lights? |
|
| |
first: i don't see how this would be any lounder than an ordinary ceiling fan. |
|
| |
second, air does not blow out of holes in the ball (for means of circulation) the air pressure difference between the inside and outside of the ball drives small fans mounted to the outside of the ball. |
|
| |
Bleh, this sounds like a dream. There's a fan in the middle, which produces airflow. Said airflow then drives air-powered motors. Said motors then drive fans? What the . . .? Definitely less efficient. |
|

I could see making a sphere and covering it with small fans, each with its own electric motor. I could see making a sphere and covering it with little louvered openings fed by one big fan inside the top. Either would look pretty, sorta. |
|
| |
i though about both of the other
options, and I almost edited it to have
one large fan at the top, but i liked the
verticaly aligned fan. I also envisioned
this made solely from plexi (all but the
main drive motor) so that the air motors
are clear also. |

I just thought it was a neat idea for a
chandelier/ fan for those people who
dont have to worry about money or
efficency. |
|
| |
Inefficiency is heat without airflow, which you don't want. But maybe the heat isn't that much. |

Am I correct to see this as a ball that blows out air on one end and draws it in on the other side, with whirlygigs mounted around its surface? |
|
| |
I may need a drawing to understand. |
|
| |
The problem with standard ceiling fans is that they create a strong draft. This new version has the potential to redistribute air in a more chaotic manner, less disturbing to any people in the room. |

I thought that was the purpose of ceiling fans. |

no. the ball blows air in all directions. the shafts the outer flablades are mounted on will be long enough to allow air to pass in one side (driving motors that turn the fan blades) and out the other (driving the motors that turn the fan blades) the outer fanblades all spin to blow air away from the ball. |

Sorry, I can not picture this at all. How about a diagram? |
