>>Sounds like pot dimensions are largely a myth
Not so fast dude.
Just got this from Rand via email:
"Pot size.....The prevailing wisdom is that wider pots are better. This is most definitely true for stereotypical stove setups because they don't capture and contain the heat against the sides of the pot like the Caldera Cone. With a wider bottom, the flame can hit the center and expand out and heat a larger area before escaping to the atmosphere because it isn't contained. Inside the Caldera, once the hot gasses flow off the edge of the bottom of the pot, they are constrained to travel up the sides continuing to heat the pot. As a consequence, the Caldera is less sensitive to pot diameter than traditional systems. It is possible you might see a little benefit on a test bench, but in the field, I doubt you are going to see much. NOW, with that said, the one thing that you do need to be careful of with the skinnier pots is to ensure the stove is centered. If you get the stove off-center where it is just going up the side and out the vents it will be much less efficient. In short, even though we sell Evernew, I wouldn't recommend you buy a new pot just for efficiency."
Not a myth, but less applicable to caldera set-ups by the sounds of it, eh?
