Solar power is ok when the sun shines, but wind power is better as there always seems to be a breeze blowing which is all that is needed for this device. The Hymini is the wind powered charger that can put the juice back into your PDA, cell phone, camera, mp3 and iPod.
This is particularly good for people who use bikes to travel on, as the breeze created will force the mini turbine into moving and then can charge up your device while you go. However it could with a bracket of some sort that could fix it to the handle bar.
