The Caldera Cone is a proven and effective ultralight alcohol stove system -- but there are a lot of options.
Today, I thought I'd take a look at a couple of different versions of the Caldera Cone system.

If you're interested in alcohol stoves, perhaps this brief look can help you decide What Color is your Caldera?
(with apologies to What Color is Your Parachute?)

Hmm.
Looks similar a windscreen we fabricated in the late 1970s for an MSR XKG and used for high altitude mountaineering. Used light gage aluminum roof flashing. Very efficient.

Hi, Ed,
I'd say this is about 34 gauge, maybe as much as 30. That's just a guess. It does make for a very efficient system.
