More wind harnessing devices are popping out. This one is a charger that gives your gadgets the juice they need via harnessing energy from wind.

With fossil fuel reserves depleting at a fast rate, and pollution already at alarming levels, designers are now focusing on greener gadgets that offer more and pollute less.

Clarisse Paula Fernando comes up with a design to charge gadgets with the Sol-Air. All you have to do is place the device near a window to harness the wind. But what if there isn't any wind? It can also be charged by a hand winder, which is of course more tiring.
