"Auf einem Dampfer, der in die falsche Richtung fährt, kann man nicht sehr weit in die richtige Richtung gehen."

Michael Ende

In 1985 rheinländisch artist Joseph Beuys created the "Capri-Batterie", a multiple in 200 copies. One of them can be seen at the K21 in Düsseldorf. He did a lot of works concerning energy and he used different materials, which in his terms were "energy-rich materials", like fat, honey or felt. But in this case he used a lemon as "source" of energy.
