Almost every great idea is born from a necessity and who doesn’t need a cellphone charger that works everywhere without a plug? And Christian Fuchs wasn’t the exception. It begins as a joke of him but later we transform it into a real project. The idea of a charger that works only with a candle was incredible. We had to build a Stirling engine for a University Project some months ago but we wanted to do something new. This kind of engine can produce energy with a low temperature difference without emissions and it can work practically everywhere.
A cellphone charger doesn’t need a lot of energy. There is in the market some emergency chargers that work manually. But there is no one who can spin a dynamo for more than ten minutes. That’s why, a Stirling Engine is perfect for this work. It doesn’t produce too much torque like the human body but it rotates relatively fast and it can be used in remote places without electric sources.
