People in developing communities around the world often own cell phones but cannot easily charge them because they do not have electricity in their homes. These users do not have a convenient way to charge their phones and often must travel to towns with electricity and pay a shop owner to charge their phone, or use a friend's electricity. We have created a standalone product that harnesses the wasted energy from open cooking fires to charge a cell phone, which will save these people time and money. Using a thermoelectric module, thermal circuit design, and electronic system, we were able to create this phone charger with a fire as the energy source. Our final product utilizes a rugged case design, which is thermally efficient. The electronic system successfully raises the voltage to a level accepted by a cell phone and splits power between the cell phone and cooling fans. Our prototype cost $278.30 to develop, however we believe that the actual production cost of each unit will be lowered to $75.80. This price point is competitive with competitors and makes Power Flame a realistic phone charging solution for these developing communities.
