Hi Bob
I don't know if you've ever been in a developing country, but tall chimneys are not required. The foliage can either be eaten by incests where it turns into CO2 after a while or it can be burned where it also turns into CO2, but we used it to boil water. I've already talked about solar and you can see my answers there. Thanks for the info about the book, I'll take a look at it when I have time.

If your installation is big enough to warrant a tall chimney, plain old burning can be pretty efficient. If you want to be nice to the planet, perhaps the best thing to do is to produce biochar, depending on your local soil conditions. It isn't hard to get 200 deg C from a simple solar oven, but it takes a lot of area to collect the heat of a small fire. You probably don't need to get up to boiling temperature, especially with a wet mix at the beginning of regeneration. Just provide a controlled air vent. For those temperatures, you don't need precision focusing, just a bit of glazing for insulation. Regarding the physical side of building things, I heartily recommend J.E. Gordon's books on structures and materials. The best is probably "Structures" but they all overlap and cover all topics. His stories are both entertaining and educational, and the writing is superb.
