The German inventor Christian Kuhtz is convinced that a good conscience is nothing that can be bought, but something that has to be achieved through intellectual and bodily labor and a fond reflection of the industrial conditions of production. His notebook is a plea for the “do-it-yourself adventure” and for an ecological awareness beyond the capitalist logic of consumption, waste, and so-called eco-technique. The featured illustrations and explanations are taken from his innovative series of booklets “Einfälle statt Abfälle” and provide ideas for a self-sufficient existence. From compost toilets, wind turbines, pottery workshops, and sun collectors to handmade shoes, over the years Kuhtz has drawn inspiring instructions for self-production. Christian Kuhtz (*1958) is an inventor, constructor, and designer of resource-friendly energy solutions. He lives in Kiel. Language: English/German
