yes… because wind flow is soooo efficient right against the window.

its kind of funny that the picture shows a non-rechargeable duracell alkaline battery.

I think the design is efficient with materials, unique and elegant. Great job.

The problem in this project is not that it stays close do a window, but the position of the wings… Being the axis of the fan perpendicular to a surface, it implies on the windflow being towards the window, wich is unlikely to happen. If it used a fan with an axis parallel to the surface, I believe it would work, specially on high floors.

How does a tampon recharge a battery?

If they modify it to charge an internal battery, and be able to hook up to a USB device to charge it, this would be sweet

This would be great until the suction cups released. Then it goes from practical to annoying really quickly.

The very basic concept here is such a great idea. Sure it’s flawed, but it seems like it could have great potential. My $.02? Up the size of a single charger so you can charge 2 or 4 at once, instead of 1.

Of course, you could also argue that, instead of having a bunch of little windmills doing random tasks within your home (as there have been other interesting wind-powered concepts on this site), just go with one big one that is a general use device.

it’s interested in eco friedly… it’s very efficicent.

Great concept with some serious flaws in execution:

(1) You must ensure that dropping the unit out the window is very unlikely — this is a deal-breaker. Suction cups never work; especially on the outside of a window which is probably not squeaky clean. Change to a more secure mount – perhaps just a simple tab that gets trapped when the window is closed. Need some kind of cable-stay to prevent dropping.
(2) I suggest a “weather vane” style self-adjusting gymbal so the prop will *always* point into the wind.
(3) I second the suggestion above of adding in a usb port so you can recharge almost anything (let the user provide their own usb cable)

Addition to my previous comment:

It’s surprising to me that the (3!) designers weren’t more familiar with basic engineering concepts. They’ve placed the *heavy* battery way out at the end so it has more leverage. The suction cup will fail very quickly.

I think it’s interested in eco friedly..

too interesting.. and cool.

awesome!!!!!

Agree with my man Zippy, this isnt gonna work. whats wrong with a regular wind turbine connected to a regular battery charger? to have it localised like this does not make sense.

Great concept though turn the fan blades 90 degrees to the window and you’ve got a success! Nice thinking on this!

Brian where is you head at? have you tried this to see if it works? how much energy goes into the production of the 6 injection moulded components.? this is a bad idea..

i think that as a concept it is brillant, but its practical flaws make it, probably, inefficient

I like it…

This will waste more energy for the car than the energy recovered in the battery, since it will significantly increase drag. The thin propeller will probably not spin, but be pinned to any surface.

But where do I get one?

yani insanoğlu aklı . neler icad ediyor .
helal olsun size ne dim yani fevkalade . şahane. bravo
perfect.

Maybe should be mounted with blade perpendicular to surface for best wind flow. Why not have the blade move in any direction following the wind current.

Anyanghaseoyo designers. Chowayo.

I think it’ll be a gruvy as a promotional product.
Be great with a mount for the car.

Where to buy this item

First of all I would like to say great blog! I had a quick question in which I’d like to ask if you do not mind. I was curious to find out how you center yourself and clear your head prior to writing. I’ve had a tough time clearing my mind in getting
my thoughts out there. I truly do take pleasure in writing however
it just seems like the first 10 to 15 minutes are
usually lost just trying to figure out how to begin.
Any ideas or hints? Appreciate it!
