SASCHA POHFLEPP ON SPACE FOOD, ALTERNATE REALITIES, AND FUTURE NOSTALGIA

Because the ship has no large windows through which photosynthesis could happen, energy for growth would have to be provided through the ship’s electrical systems, which take in energy through solar panels. Instead of converting the energy back into light, the organism, in this case a modified yeast culture, could be altered to consume electric energy directly through electrosynthesis, growing around an electrode in a liquid medium until it is ready to be harvested and eaten.
