Bicycle-Powered Cell Phone Charger

D-Lab students worked in Calcutta with visiting Tanzanian inventor Bernard Kiwia on his design for a pedal-powered cell phone charger made out of bicycle parts. Rubber parts and molds were made in Mr. Maulick's workshop. The charger is now being manufactured and sold by a social enterprise called Global Cycle Solutions in Tanzania.
