See the link below for a video with the details ... basically the vibrating film causes a magnet to move between coils ... which is effective in light breezes ...

" ... Shawn Frayne, a 28-year-old inventor ... saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. ...took a new tack, ... Frayne's device, ... is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. ..."

This is so do able! Yes! Thank you. I recognized those coils imediately... I built a motor in grade school for the science fair......How cool is this, so simple why didn't I think of it! how innovative!

They'd need to be. Microturbines pretty much suck. There seems to be no attached cost beneifit analysis so I assume it's still not fiscally effective.
Good that theyre getting closer though. I wonder if something can be worked out using old fashioned computer tape? It's strong, cheap, a ribbon, manufactured roll to roll, and the whole thing is magnetic.

FYI: I mentioned this in today's round up of news: http://current.com/items/90373734_third-world-wind-power-first-look.htm

If you google windbelt you can see his other ideas for it's use. ie.: You can put them inside duct work and they can power the temp. readings! The air flow itself powers the windbelt How cool is that!!! No more changing those batteries.
