100% i figured id ask around to see if anyone had heard differently and thanks for telling me about the different levels of firebrick that's something I hadn't realized was a thing

im not sure if this video is what you are looking for but my impression is that a temperature difference will cause the soil to "breathe"

eric "free nitrogen in the air starts burning" is the bit im having trouble with the folks above are saying that the conversion of n to NO2 takes energy out of the environment. is NO2 able to release a small amount of energy that would add to the heat the rocket mass heater releases? i heard somewhere that rocket mass heaters can get hot enough for NO2 to form.

Thanks for the replies y'all!

I remember hearing or reading about some folks doing some really effeicent rocket mass heaters where it could get up to those temperatures and i read them when oxygen and nitrogen combined a little bit of energy is released which would help support combustion. And a good while ago I think I remember reading something about a methane atmosphere or a nitrogen atmosphere and what would happen if you put oxygen into the atmosphere and if I remember right you had something that was like a reverse Flame and I think there may have been a lab testing component to it.

i talked to my grampa and he told me that nitrogen the gas cant burn, is it that organic nitrogen can burn or am i missing out on something?

once you get enough chickens or more than a few larger animals they might be more accepting

I asked matt powers how he would build a biodome and he said he would make 60% or so of it aquaculture.

I think they are full of ammonia.

from my understanding, icy balls rely on the ambient temperature of the room to evaporate the ammonia then cold or cool water is used to condense or something along those lines. i recommend you check wikipedia or youtube for more specific information it took me a few months to get comfortable with such an item even existing much less how it worked

If you want much larger, as for a community, perhaps a yakhchal?

I actually found out about the yakhchals a few years ago from searching about systems related to zeer pots, while this one is a bit small looking thats mainly because i dont have much skill with drawing though i am curious how small you can make one i would likely make this example full size or larger
