Very good invention. Some Fan manufacturing companies in India designed a bend at the end of the fan blades. But in the past in India in Government Offices,hospitals,Churches etc., there used to be hand driven PUNCA(FAN) with a wooden plank 1.5 m length and 40 cm width with a cloth twisted hanging at the bottom. There is a pulley to facilitate horizontal motion. A human used to pull it. The advantage is you get horizontal motion as such gentle air. As the swept area is more, more room gets gentle wind. This can be modernised with a motor. Also one can paint pictures on the wooden plank for beauty.

Also I designed a horizontal hand fan by attaching a hand fan of Palmyra leaf to Wiper motor. As Wiper oscillates in a horizontal way one can get gentle air. Of course one has to convert DC into AC. By placing this innovative fan in froe, one can get gentle air.

i\'m surprised dyson hasn\'t tried his hand at making his \'bladless\' fan into a ceiling fan design.

I\'m wondering if this design has any applications for boats/submarines....

A design that creates a vortex? He should shop this to Vornado. It would be a perfect fit with their line of \"vortex action\" air circulators. As long as it\'s reasonably priced, like $100, I\'d buy one.

When not in use, it gives the appearance of art.

I wonder if this has any implications for helicopters!
Coaxial rotating ribbons would be much stronger and lighter than the single rotor blades, and probably require much less maintenance.
I wonder just how fast they can go?
Running chopper rotors where the tip approaches the speed of sound creates some interesting problems.
And by \'interesting\' I mean \'bad\'.
Hmmmm....

awe some !!!!!!!!!!!! great dude ..........PERFECT AERO SHAPE BLADES :)

Would take forever to clean it !!!

I don\'t care that I\'ve got low cielings, when these come out, I\'m putting one up!
Looks like astonishing good design to me.

that\'s using the ole\' noggin.
