Self Supporting Feather

This is a drone motor that is attached to a feather with sensors that allow software to sustain the feather in the air.

In which Voice explains the sound of a single feather flapping http://www.halfbake...er_20in_20the_20Air

       Umm... It... I just don't know any more. There's not even enough of an idea for it to be wrong.

       Maybe it's some sort of Zen ? "The sound of one feather flapping" ?

       more like one feather writhing; I don't think any actual flying would be involved.

       All these feather ideas from [JesusHChrist] make me wonder if he might be feeling ... down.

       Nahhh, He's just a little under the feather...that's all.

       There's probably a reason why birds have evolved to have more than one feather

       yes, they need two at the very least. [norm] you made me laugh.

       As I discussed in a different idea, linked, you don't actually need an aerodynamic opposing force if the motor is strong enough. [JHC] if you would come up with the math to prove it you would have an actual idea here. The problem is you still think it can move around in a circle in the air without flapping AND with nothing opposing its motion. That's called "reactionless force" and the laws of motion forbid it. You could add a rocket to oppose its movement, but then it all becomes a bit silly doesn't it?

       hmmm... you could do a weighted motor that, once its maximum speed had been reached, reversed. Of course you have to reverse the feather as well, then.

       [norm], pull your trousers up. It's not big, and it's not clever. But mostly, it's not big.

       is it possible to make an air celt (reverse spinning oblong)? if it is then you could filamentize the surface (maybe) to get two directions out of one shape.   

       [JHC} I visited your web page and I noticed you actually made some things out of feathers. It is impolite of me, yet I am wondering if you could also invent things without feathers.   

       Do as you think right though. Perhaps you are on to something wonderful and I just do not comprehend.

       I would also like to impolite and wonder the same thing.   

       Also, [beany], could you be an angel and post a link to [JHC]'s web page?
