Bob, I made a neat discovery online. It is a small campstove that cooks efficiently with sticks, tree bark, pine cones, scrap lumber, and other biomass fuels!
You can buy it from the Deadwood Stove Company.
We’re getting one because my family can not function without a good, hot cup of coffee in the morning, and boiling water using charcoal seems a waste (we choose not to use propane except for a burner used for pressure canning outdoors).
I have stored 50 pounds of coffee and have a manual bean grinder. Ain’t no way we’re going through the end of days withoug java!
Yea, I’ve heard of that also. Not bad, as long as you can keep it fed. You’ll find that wood products burn much faster than an equal volume of fuel - but then it’s possible to have an unending supply of wood products. So, not a bad plan for long-term, and probably more reliable than a solar stove (which looks like an accident waiting to happen).
