In the exhibition FUTUR II, coal plays a central role. As a starting point, Thomas Feuerstein uses algae (Chlorella vulgaris) grown in specially designed glass objects or bioreactors. The biomass of the algae led to the title sculpture FUTUR II, which by way of a chemical process of hydrothermal carbonization transforms the organic material into coal. As if in fast motion, the plant cells transform within just a few hours to coal, a process that would normally last millions of years. In so doing, coal is produced for art. The coal produced in this way is pressed into crayons that Feuerstein uses for his drawings.
