Well, one was the underground air filtration. I’m sure someone has tried many methods somewhere ? Another is to simplify the lab, at the same time as controlling every aspect of the chemistry through creating your own personally adjusted solutions, but made simple for the common man. Big business and academia like to corner the market on thinking, thus manipulating the public as a control mechanism. I always seek to change this. I’ve had many ideas. Maybe it’s time to start writing them down, working them in theory, testing them, and sharing my results. This will help create a more “ think tank “ type atmosphere. But for now, I seek understanding from those more experienced to get a foothold.
