Greetings, all. Last year I published a short illustrated book on appropriate technologies including passive solar design strategies, heating devices, et al. It is a basic primer and will not present much if any new information to long time permies, but I thought it would be worth a share as a starting point for anyone who is just getting familiar with these concepts. I hope someone finds it useful.
