Jim,
I don’t know if this has been posted here or not. I have finished watching a series on the Science Channel called “Invention Nation“. The show primarily feature inventors who are inventing ways to “go green”. Many of these inventions and ideas fit in perfectly with being self-sufficient. Some of the topics are; used cooking oil for diesel engines, solar power technology, passive solar for heating homes and water, bicycle generators, etc… The series will rerun starting in March and may be worth a look for the preparedness minded. See the Invention Nation web site [1]. Thanks to you and your family for all you do. – Randy G.
