Not sure where this belongs, but
here's a link to the powerpoint slides that were part of a University of Wyoming Enrichment Programs class I taught this past week. It hits pretty hard on the decisions involved with actually designing an off grid house: less on the Why and more on the How, which might have lost a few people.
I don't reckon it's my job to sell this lifestyle to anybody; just to offer our experiences, what works and what doesn't.
Cheers!
