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? |
|
| |
Well, I guess I need to ask a blunt, and possibly brutal sounding question. I'm not trying to be mean, I just want to make sure we're all on the same page here. |

These "air-powered motors," How are they different from... pinwheels? Windmill blades? I think it is these devices which are causing us a bit of confusion. |
|
| |
In short, aside from fan blades, and a central axle, do they contain any moving parts, which would warrant the need to use the word "motors" to describe them? |
|
| |
Is it not the central fan which is providing the motive force (via wind-power) for all of these others? And is not the simplest way to deliver this power through the passive process of having the wind spin the fan blade? If so, I'm not sure that there's any functional purpose, although it might indeed have a cool effect... especially if it was all made of clear prismatic material, and placed in sunlight. |
|
| |
Then again, there's also a small chance that some of the curves needed for the blades might include parabolic sections, and you might burn someone's house down with it. I think it's worth the risk though. |
|
| |
//no. the ball blows air in all directions//
You may not have meant this literally, but if it blows in ALL directions, then it will do nothing but create a small cavity of low pressure at the center of your ball. |
|
| |
Nope, don't get it. Where is the intake? This sounds like a a cool lamp, not a fan. |
|
| |
PS if you want to move more air but not have a draft, use bigger blades moving slower: bigassfans.com, we are putting them in our warehouse. |

Better to fix them to your ceilings, shirley ? |

Standard fans circulate airflow vertically downwards in the centre of the room and upwards near the walls, creating a toroidal airflow. The spherical fan would create multiple airflow vortices in addition to the major torus, giving rise to self-similarility. |
|
| |
"Lounder" is a measure of fractal dimension in choatic flow systems, so a spherical fan will create flow with more lounder (or "be more lounder" in lab parlance) than a standard ceiling fan. |
|

I am more skeptical of the "360 Degeres" claim, the Degere being of course a unit of refreshment (invented by Monsieur Dégere), with one Degere being equal to drinking a single glass of water at standard room temperature and pressure with a body hydration of 60.0%. 360 Degeres works out as being equal to going ice swimming in Antarctica after spending thirty six years in a sauna. |
|
| |
If you want a ball that shoots air, why not hang the ball over a vent? One big central fan could then power multiple blow balls. |
|
| |
Or just have a huge fan under the floor and a ball pit in the room... |
|
| |
OR you could line the floor with shredded newspaper and wood chips, and install in-door hamster cages everywhere! |
