Something else HJ
I am fascinated, no , I am OBSESSED with letting no atom of substance, or photon of energy, escape unused. What I mean is to have maximum efficiency possible. So, the caldera and few other designs ( like the Swiss Ranger stove) offer what I absolutely love in a stove which is a built-in windscreen to comletely surround the pot (almost hide it from view) and guide the heat to engulf the pot from all sides, not just the bottom. Even the escaping hot emissions, keep touching the pot to the last moment.
This is the same reason that I absolutely loved the rocket stove made of mud in some 3rd world countries ( seen in u-tubes) .
So, HJ, do you know more of such designs that minimizes escaping heat and focusing & condensing the heat around the pot ???
If you
really want efficiency, check out a Trangia 25 series or Trangia 27 series stove. They're pricey, but they are going to extract every last erg out of the alcohol.
A (much) cheaper version is the knockoff Ledmark set. They're available at campmor.com for $20.00:
Ledmark Alcohol Cookset.
The Caldera Cone is a cottage industry product and is a little pricey. For bugging in, the weight isn't going to be as big of an issue, and the Ledmark set will do you.
As far as fuel, check out a paint or hardware store. If there's a marine store near you, check out fuel for stoves on boats. Denatured alcohol is pretty available across the US. Methylated spirits are often available elsewhere. Methyl hydrate is sold in Canada and will work in alcohol stoves (I believe it's methanol).
Charcoal lighter fluid is typically petroleum based. I wouldn't use it in an alcohol stove.
