Shortly before the Solo Stove came onto the market, I met some of the inventors at Maker Fair in Menlo Park, CA. They were part of a group that was trying to engineer a low-smoke stove for indigenous women who spent most of their time cooking.
Instead, the women didn't use it but the men used it in the evening to stay warm.
I have a couple of Kelly Kettles (portable rocket-stoves), and one is for water and the other is for sand. The sand-filled one is a heat battery - charge it up after boiling some water with the other one, and bring it in the tent to keep things positively toasty.
