you can do lots of searches thru Youtube and find all sorts of "penny stoves", "cat stoves", etc...

i always laff when i meet someone who is very familiar with these types of stoves, and are proficient at their use.

the paradigm shift is....

with a stove you buy, obviously there is this object that you now use, when or if it should break, you have to buy a new one. in the mean time, its junk, or you have to try to fix it, etc...

the thing with these "cat stoves", etc...
is that
now the skill
the knowledge
is in your head

its a skill
its a learned art

suddenly now all you need is a few teaspoonsfull of HEET, etc

literally you can pick up a couple of cans from the side of the road, and make a stove

I'm guilty. I have at least 3 different stoves.

my favorite has been a SnowPeak mini giga... isofuel stove

now my favorite are these "cat stoves"

what i don't like, is making trash
what i like is using trash to cook my food...
that is...
there is something gratifying by cutting up a can to use as a stove...

somehow i think that is cool
and what always blows my mind, is how well they typically work.

just like any other skill
its all in the way you make your stove, and how well you shelter it.

peace...d
