The green carpet is an algae farm and sun shade for inside use. While playfully referencing natural structures, it shows the relation of light and air through photosynthesis. The green carpet changes the effect and perception of the sunlight within a room, shading, colouring and breaking it. Translucency, materiality and lightness of the LDPE-foil suggest a new interaction between human and photosynthesis. Using widely accessible industrial material and open-source production methods creates the possibility of decentralized local production to easily enable a natural process.

Algae organisms are powerhouses of photosynthesis, producing big amounts of the worlds oxygen. Some of which is used by fish and other sea creatures, and some of which escapes into the air. They transform carbon dioxide dissolved in water into simple sugars that are used as food by the algae themselves. In turn, the algae become food for other creatures above them in the food chain. In this way the photosynthetic algae are a fundamental source of food on the planet, being autotrophic, which means they create their own food from sunlight, water and CO2. This allows a fairly easy and circular farming process. The produced nutritious biomass can either be eaten, composted and used as fertilizer, or used for the creation of bioplastic or biogas.

The project started at the HfG Karlsruhe under supervision of Chris Kabel and was further developed with Martin Postler and Benjamin Unterluggauer, both teaching at Muthesius Kunsthochschule. It uses the open-source CNC welder designed by Benjamin Unterluggauer for production and was strongly inspired by ecoLogicStudios' work.
