In 2012, students from the Saint-Etienne Ecole des Mines (National Graduate Engineering School) linked up four bicycles so that the public at the "Curieux Voyageur" film festival could pedal to produce electricity. In 2013 the bikes are put aside, the pedalling stays and the rest is invention. The "Curieux Voyageur" film festival remains the conductor, the Ecole des Mines and the Saint-Etienne National Engineering School deal with technical matters, Bp Design agency deals with the functioning, and Héliose the animation. The goal is the same: to produce green electricity.
