For sure, there are many ways to dream up variations upon an existing still type, I have looked at lots, and admire the ingenuity of their devisers and builders.
At the end of the day, they all do the same thing.
OR AT LEAST SHOULDAnd some have been quietly doing the thing that they were built for, for years.
Some are faster, some slower. And some may be made of Ticky Tacky,- but they all work just the same.
Concentrating clean, or deliberately flavoured Ethanol.
I know that Ice enjoys the wide variety of stills in use, and while currently building a new Ice-bot of his dreams, he is not a "mine is bigger/better than yours" kind of guy.
Myself, I am working upon a still that uses 3 polystyrene cups, four drinking straws and a deck of playing cards, not because I think it will produce good product, but because all components should be available whilst detained at HMP.
