The Spark, created by JikoPower Inc, is a hand-held thermoelectric generator that converts excess heat from any cook stove or fire into useable electricity. Meticulously engineered to be rugged and reliable for users' greatest adventure or everyday life in off-grid rural Africa, the Spark keeps cellphones, LEDs, radios and more, ready to go.
The generator is made from aircraft grade aluminium alloy and has a power output of 2-5 watts and a heat tolerance of 600˚C.
Thermoelectric generators, or TEGs, rely on thermoelectric chips that convert heat into electricity. The thermoelectric chips generate the most electricity when the disparity between the temperatures on either side of the chip is the greatest. The JikoPower Generator gathers heat through the arm on one side of the chip and the water in the reservoir keeps the other side cool. The water can be boiling and still be considered cool relative to the side with the metal arm.
The device uses heat that is otherwise wasted when people are cooking. It is used while cooking or enjoying a fire, so it can't be easily stolen. It is very durable; perfect for rural lifestyles or camping. It also doesn't rely on the weather or time of day to function.
The Spark recently took the gold medal in the power source category at the 2017 Edison Awards in New York beating Industrial Technology Research Institute (ITRI) and Stanford University's aluminium battery
