Projects by Arvid Riemeyer, Christa Carstensen, Jesse Jacobsen, Karl Sperhake and Paul Meyer are part of the exhibition Transform! Designing the Future of Energy at the Vitra Design Museum.

Harvest/Light is a table lamp that uses a parabolic mirror in two ways. Firstly the mirror serves as a sunlight collector to focus as much light as possible to charge a battery via a small solar panel. Secondly the reflective mirror bowl serves as a lampshade to direct the led generated light. By switching between sunlight collection and light generation the product harvests the sunlight to
generate artificial light by one flip of light module.

Harvest / Heat Energy is a product that uses an adjustable fresnel lens to focus the sunlight to use hydrated quicklime as a thermochemical energy storage. The focal point generated by the lens is burning the limestone generating quicklime CaO. Lime is one of the cheapest thermochemical storage materials, environmentally friendly and already available as an industrial mass product. Quicklime can be stored airtight and rehydrated generating heat energy via a thermochemical reaction.
