Very nice! The US needs to get something like this. The boilermakers are nice, but quite expensive. I have one of the old italian brew kettles, but I think they stopped selling them because of the shipping costs. Interesting to see how brewing evolves in other countries. Darwin was right!
As far as your schematic and sculpture, you guys clearly know what you're doing....but if you're splitting the beer amongst 6 people, you're gonna have to brew frequently!
