Further informationson the exhibit "Television Bicycle"
By pedaling you get the wheel moving, just like when riding a bicycle. However, the bike does not stand on the ground, as is usually the case, but on a generator. The rotation of the wheel sets the generator in motion. The generator in turn produces electricity and transmits it to the connected television.
As soon as enough energy is generated by pedaling, the TV turns on and the connected camera starts filming the cyclist.
