Mounted between two sheets of plexiglass and displayed in a zinc frame, this drawing has been transformed into a three-dimensional object. The conical shapes are reminiscent of stylised cooling towers from a power station, complete with smoke at the top. This reflects the artist's interest in sources of heat and power. The two crosses represent positive energy. Beuys's choice of zinc for the frame would have been a deliberate one, as he chose his materials for the qualities they represented. Zinc is a metallic element and an essential mineral for life, but equally is poisonous in high concentrations.
