There was a small 1 gallon counter top draft system, called SYNEK, that used like 1 gallon mylar bags to keep the beer in. They are starting a Kickstarter in the next couple days.
Another new item was a smaller Brewhemoth that was unveiled. It was basically the same as the normal one except more in the 14 gallon range.
The SS Brew Tech stuff has been around for quite some time (though I admit I like their small conical).
The Clear Draught System has been around for awhile as well.
National Chemicals had a new cleaner that came in tabs and was meant to be dropped into a 1/2 to 1 gallon growler and left to sit to clean it. I got a sample but have not tried it out.
Not really new but I never saw it before O'Connors Homebrew Supply has a large pitch of a 'West Michigan Ale Yeast'. I picked up a vial to give it a whirl.
There were these 'TurboPots' that had finned bottoms and were suppose more efficiently use the heat from your burner and heat quicker. Looked pretty interesting. http://www.turbopot.com/
The turbo pot does look interesting. Seems like one of those ideas that looks obvious after someone else comes up with it.
I wonder if making each fin a "swirl" to the edge of the of the pot would be ever more efficient? Of course the manufacturing cost might out weigh the benefit.
I said "why wasn't this done before for pots". Finned heat exchangers are in wide use. Those fins looked like they were machined in with a CNC machine. Spiral might be only marginally more.
