Some apptech worth checking out

From left to right:

100L stainless 'Stockpot Biochar System' (SBS) Top-Fed Open Draft kiln with cogeneration possibility on a cast iron hot plate/griddle at the beginning of a burn before making biochar (not yet prototyped)
The 'Chimney TLUD' made from 304 stainless 6" chimney fllue for a pizza oven eg.Bakerstone (not yet prototyped). Could also be fabricated from 6" 304 1.6mm exhaust tube if you've got a powerful angle grinder and can access and afford the steel.
The '3 in 1' 'Flat Permastove V4' TLUD (prototyped) made from 304 stainless, for an outdoor kitchen, multi-day trekking and car/base camp with additional chimney piece and 'Champion' pot stand (soon to be replaced with a 'Universal Pot Stand' (UPS) - not yet prototyped) useful for slow cooking with a cool fire eg. curry in a Kadhai or whatever else you want to cook or boil
The completely 2D laser cut and flatpacked 'Flat Permastove' TLUD (prototyped) made from 304 2.5mm stainless with 15L stainless stockpot for boiling water - this guy can burn pretty hot which is good for boiling large volumes of water, eg. emergency WASH. Although for this design the biochar can be retrieved after a burn with a little difficulty, in order to maximise the thermal energy from the feedstock for water boiling (where the solid fuel wood/rice husk pellets need to be transported over long distances=transport fuel and shipping volume), the biochar could be ashed and it would still be a C neutral burn. If you are interested in buying the CAD for it, please reach out on the 'Contact' page and we can negotiate a good price.

And, for a '3 in 1' indoor and outdoor kitchen (and possibly car camping too), I recommend the off-the-shelf 'FabStove' TLUD designed by Ekasi Energy - if you can afford and access one?
