The lower section of this three-part work appears to be a schematic drawing of a turbine. It may be the item which is intended to be fitted inside the box at the centre of the work, to power the propeller on the right. Beuys used the principle of electricity and machines in some of his sculpture, so this work may anticipate a later sculpture. Electricity was, for Beuys, part of the much larger issue of energy and, in particular, of ways in which the key issue of human energy (creativity) could be harnessed.
