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. 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.
After some months of planning and construction, the first technical drawings and assembly instructions were finished and the Stirling charger V. 1.0 was ready. Because of some engineering issues like power optimization and production difficulties, a new version of the charger was redesigned and one month later, the version 2.0 is ready for a prototype production. The first prototype of the charger was planned to be finished on February 2014 but we are currently at the end of our Bachelor degree as Mechanical Engineers in Germany and it was really difficult for us to continue with the construction but we are open to continue with this idea in the near future.
