>geodesic dome greenhouses

I have looked into them before. The space is very aesthetic, but for space utilization I'm going with a passive-solar-energy, tricked-out, glass greenhouse. I have piles of stone, block, and patio door glass.

VAWTs are easier to maintain and I won't need a super tall pole.

>You sell some crops and thats about it right?

Correct.

And here a proper rocket stove made using larger cans. I've used this one about 60 times since 2016. I like it a lot.

I just use a tincan rocket stove. If I make a masonry one, I'll use rockwool for insulation. Just remember a rocket stove needs 3 main things, an insulated flue, a flue tall enough so the flames don't touch the cooking vessel, and be feed fuel from the side via a tube. All those short ones you see online aren't properly made and more fuel inefficient. Only when they burn clean, unseen flue gases are they ate peak efficiency. White smoke means wet/damp fuel. Black smoke means the fire box is overloaded with fuel. Clear flue gas means everything is just right.

So long as the heating coil is above the original rocket stove flue., yes. The instant you stick it down into the flue below where the skillet is, it will cool the flue gases, ruin the efficiency, and soot up everything. The same thing will happen if you coil it around the flue.

Also consider using a wood gas stove. They are more efficient, but much the same. You'll be able to load it with biomass and have a controlled burn. Rocket stoves on the other hand don't have a controlled burn like that since you are always feeding it a bit differently each time and they need refilled often.

You will also need a very high flow pump if you have lots of coils. Those things get pretty hot very quickly. Less coils = less flow needed. Inside diameter of the pipe you use plays a big role in how it will perform. The larger a pipe you can us the better off you'll be to prevent steam blowoffs and it will flow much better. It won't heat up super fast either, but the net effect of heating the pool will be the same.

Don't use a radiator or fins. Just use a straight pipe up above or a coiled pipe the heat existing the flue will flow through.
