Electricity from cooking fire
Based on the outcome of Berkeley Lab's extensive research, the Point Source Power of USA has designed a device called VOTO fuel-cell charger which can be charged with any cooking fire by placing one end of the device in a cooking stove's fire. VOTO's battery can receive full charge roughly on two cooking sessions. In addition to phone charging, the device has also an LED light which receives power from the same source. When fully charged, the LED light is capable of providing light for 30 hours.
The creators of VOTO have two marketing targets. One, the campers in the developed world; and two, the developing world where electricity is not readily available but cooking fire is. In Bangladesh, VOTO can be used for charging cell phones as well as for lighting purpose in the remote villages and costal areas where electricity is not available.
