I think a lot about the collapse of the economic systems we are used to having. It's not like I'm going to stop living to prepare for that. Anyway when there's no FAA then Amazon and Google, etc, can get serious about drones. But I've sort of been wondering about chemistry with plants and other farm products. I'm curious at this point about how I can begin thinking about how to get a purer form of nitrogen from chicken manure. Any answers are appreciated.
