When you get off a plane from Europe to sub-Saharan Africa, you are often greeted by the smell of countless open cooking fires dotting the land. It’s quite nice in my opinion, though it’s not healthy for those who use them.
Interesting bit. I have a van with a 100 amp hour lead acid battery and an inverter. You can run a microwave and an electric kettle off it. Seems that solar panels + batteries would be enough for cooking.
Unlike solar panels and batteries, rocket stoves can be made with dirt.
