I had started making a rocket stove when I was run over.
We have not talked in a long time on here really. We had a chat in comments a month ago but if you recall when I joined here 14 mths ago, I mentioned it..... so my life has changed a lot since the car ran me down and the state is burying my file, to ruin me.
- so clearly you understand all this stuff, by what you just wrote.
I will tell you I have slept outdoors in the hammock in that setup down to -15C (which is super cold for Americans lol)
-- and in a full MMSS sleep system, I can sleep down with proper baselayers on my body and a toque or similar down to like -40 and be comfy, not even making that up.
I have a semi tech. bag and wool everything now --- wool is so awesome LOL
