Got a new stove recently and finally had time to put some pics on my computer. It's a Trail Designs Ti Tri Design Caldera Cone made to fit in my Snow Peak 700 Trek Mug.
According to Rand at TD, the Fusion is "2 titanium cones that will fit completely inside your [snow peak 700 which has long handles that make a fissure not work] and will be wood fire capable ...
He also described the difference between the the Classic and the ULC. He said "The Classic Caldera or Ti-Tri will go all the way to the top of the pot and is the most efficient. The Fissure was made to be a "classic" in that sense, but made out of 2 cones to fit in the pot." The ULC is a single short cone that will fit inside the pot. And "the "Fusion" is a fusion of the ulc concept and the fissure concept."
I have always liked to use my weight savings to bring a cup along with my cook pot so that I can have a warm beverage AND a meal at the same time without having to eat out of a bag. I often eat out of a bag, but this keeps my coffe/food pot from smelling like whiskey on occasion or lets me make coffee before doing dishes if I care to.
I have the TD Fusion, inside a snow peak 450 mug with the 12-10 stove inside, and a Ruta Locura carbon fiber lid on top. Here's the unpacking:
