Those are both good suggestions. However I did do the research on the solar part and it takes alot of panels to heat with, and placing the fire away from the cabin does not serve a heating need. So what I have found is if you are in a tent or tippee or cob home, you can dig a hole to put the fire in and dig a tunnel out the bottom of the tent to the outside, like having a chimney pipe but out the side on the bottom of the tent or cob home. This will eliminate the smoke. There is a good video on You tube. But an after thought, about having the fire remote from the cabin, you can always use rocks and heat them in the coals of the fire and bring the rocks in a sack to the cabin and place them around the cabin and in your bed, for the warmth. Thanks for sharing.
