Designer Tjeerd Veenhoven took a cue from his native Holland to create the iFan, an iPhone case with a built-in fan for charging. Pop the phone into the case for your bicycle commute to work and let the juice flow. The design is still in the beta phase:

[It takes] 6 hours to charge my phone, rather long I think...but it works. I can shave off many charging hours by redesigning the fan blades, making it more efficient in catching the wind while sun bathing at the beach, doing walking trips in the mountains or just holding it outside your car window while driving along....

While Veenhoven's been getting plenty of blog love highlighting the device, we looked into his blog and found plenty of other ID projects worth a gander. Check out the Operating Room of the Future project he mentored on and his Carbon Bike--made not from carbon fiber, but carbon wire drenched in epoxy resin--for starters.
