Visited CalPoly and was pleasantly surprized to see Energy Basis for Man and Nature in their collection.

Howard T Odum was a progressive ecologist of the 70's.
He wrote some fundemental concepts of permaculture.
I believe 15% of permaculture design graduates will
ever touch this book. Repressed by educational
institutions and even the permaculture forum have
neglected his research.
I think he was ahead of his time.
