The idea I came up with for the Atomhawk Solarpunk contest was that in the future, this civilization has found a way to harness the potential of a certain bacteria, or maybe they learned how to use it in conjunction with other chemicals, other types of energy etc. So, it's a way for them to live off green energy in the form of organic matter that can sustain an entire world. This idea was inspired by my recent interest of brewing my own Kombucha at home. The Kombucha requires something called a SCOBY (Symbiotic Culture of Bacteria and Yeast). This organism needs to eat sugar for a week and it gives me a delicious drink for the hot summertime that we are experiencing this year (ironically due to global warming?). So I thought that I could take this idea further and allow it to drive the progress of an entire futuristic civilization. Here a spaceship is being grown in an open exhibition hall space.
