Winter Stove/Pot Modification Help
Increase thermal efficiency of stove/pot, reduce fuel and subsequently, weight.
That's the basic idea here. I have a thin-walled titanium pot that acts as the best darn radiator of heat you've seen. Trouble is I want the heat to stay in my water and not get dispersed into the winter air. So I'm trying to find a material to wrap the pot exterior with that will insulate it from the winter air. It must be fireproof due to the fire below. Some interesting metrics: alcohol stove flames reach 650-750 degC, campfires can reach 1000 degC. Glass melts at about 1000 degC.
Idea one was a 1/4" ceramic fire blanket. These things can take 1300 degC sustained. After discussing it, however, I was reminded it is fibrous and while not as bad as asbestos, if it gets in my food or water... it'll get into me and cause some nifty problems.
Idea two, directly off the previous conversation, is a double boiler. Somehow wrap a second wall around the first, separated by air (not a windscreen) and secure it to the base and top rims.
Idea three is... you guys. Let's see if we can pool resources and come up with another idea.
