Trangia don’t have the heat capture rings but it looks like you can mod Optimus burners to work in their aluminium wind shield kits. Got a lightweight aluminium set to give it a go.

Thanks for the tip.

Finding a non teflon coated aluminium pot with a heat capturing coil for lightweight hiking is impossible last I looked.

Just removing teflon from stuff is a huge pain too, it’s dangerous to burn it off, I might try and sand blast the Teflon off the one I have. I have to research how bad that is, probably makes way too much toxic microparticles. But it really shouldn’t be so hard to find food appliances and cookware not coated in this crap.
