Beuys has combined his favourite matt brown, ‘Braunkreuz’ floor paint with fat to create this work. The artist commonly used animal fat in both his drawings and sculptures along with a variety of other substances that he saw as central to human survival. He related these to traumatic, ‘near death’ experiences that, according to Beuys, he experienced during the war. The title of this work refers to Beuys’s interest in the generation, storage or transfer of energy and can be related to similar drawings of batteries from around this time. It also suggests the idea of spiritual healing from within, a concept which was hugely important to Beuys.
