Products of the Sun

Products of the Sun is an interdisciplinary seminar aiming at embodied experience of post-fossil futures. Students develop prototypes for heating water for a tea ceremony using only renewable energy sources. Combining solar cookers and photovoltaic-powered stoves the seminar explores how a small-scale energy infrastructure can be designed for the orchard of the ZKM to support human use while minimizing environmental impact. Through practical prototyping and critical reflection, students engage with questions of energy, ecology, and design at both the product and systems level. The seminar is a collaboration between HfG Relational Design and KIT Art in Architecture.
