I loath cell phone pics with a passion. Never mind the sideways stuff, it's like "Jeeze, that might
be really interesting, but I can't tell from that pic!"
And from the linked article: "a gas silininoid valve to control the flow of propane into the burner."
"Silininoid"? I weep for the future.
Anyway...You ever wonder if the folks at Blichmann are just messing with our heads?
