Like wind-mill.. We can try to make use of the pressure that occurs when you are driving a car or sitting in an open bus. In India some of the village buses got open windows, normally buses drive at 50km/h which inturn forces lot of air in your face, we can use this wind power to rotate a set of fan blade like plates and turn that roatation force in to motor energy. This motor energy can create DC electricity which can be used to charge your discman battery or cell phone battery.
This idea can also be used while using car escp when you are driving from LA to Texas or CA.
Late back Chinese-Taiwainese introduced a kind of self chargeble fan with batteries in it, this fans had a larger market swipe in north India once. The same idea can be appiled for this.
May have good market in Asian and African countries.

Re: Air/Wind based battery charger
yes, thats definitely interesting. But most buses have moved to using closed wondows with AC. But I agree with your idea of harnessing all the power around us instead of depending on fossil fuels and other kinds on non-replenishable energy.

hi
have u implemented this idea???
as even i was thinking on the same line....unaware about the fact that even u were thinkin on the same line

And now, someone is doing it practically.

Scientific American reports that Xcel Energy, a Minneapolis-based utility company, has started to test a new technology to store wind energy in batteries. The company is currently trying it in a 1,100 megawatts facility of wind turbines in Southern Minnesota. The company started this effort because ‘the wind doesn’t always blow and, even worse, it often blows strongest when people aren’t using much electricity, like late at night.’ It has received a $1 million grant from Minnesota’s Renewable Development Fund and the energy plant should be operational in the first quarter of 2009.
