So while watching my latest batch bubble away just now I had a thought.
It seems like it would be relatively easy for one to put a little paddle-wheel in a ventilation lock so that the escaping carbon dioxide turns it, and have it connected to a digital or mechanical device that would count the turns and thus you could calculate how much carbon dioxide it has put off ... from which you could presumably calculate how much fermentation has thus far occurred.
Does this already exist and/or thoughts?
