Futurology

I've been surprised by how little I've heard about this kind of research in the past. There's Air Company vodka, and a startup useing hydrogen bacteria to make a sort of egg white, but I had to dig a lot to hear about either of those.

Basic biology will tell you that very little energy passes all the way through a trophic level, so food production should be much, much cheaper at scale if we can do it like autotrophs. Farming will inevitably be replaced, at least in part, one day.
