Metabolism is focused on developing functional self-renewing systems capable of sustained long-term growth in changing environments. These systems will be integrated in artificial skins and fuels showing qualities of living, composed from fluid-based inorganic chemistries. Synthetic systems of metabolism could act as a regenerative layer for building surfaces, similar to ivy on building structures, and extend beyond the skin to proliferate through the scaffold. Chemical bodies integrated as part of scaffold sustain a kind of the livelihood while being contained. Projects include:  Microbial Fuel Cells; Carbon Exchange Systems; Skin Building Systems.
