I see a bazillion stove designs out there but am having troubles figuring out how they actually perform compared to each other. Any sites focusing performance comparison? Basically, I'm looking for a solid stove design that can boil 1l of water, 1-2/day for up to say 4 day. Nasty cat? Penny stove? Gram weenie make says his isn't a good fit. I need help narrowing the choices. I think I would prefer a sideburner since that eliminates the pot stand, but I'm open to anything so long as it is light, efficient and can do a full liter.
