REALLY saving energy: Paul Wheaton at TEDxWhitefish

Paul Wheaton, the bad boy of Permaculture was proclaimed by Geoff Lawton in 2012 the Duke of Permaculture. He is the creator of two on-line communities. One is about Permaculture, Permies.com, and one is about software engineering, CodeRanch.com.
He is a powerful advocate of Sepp Holzer's techniques for which a recent study showed they have the ability to feed 21 billion people without the use of petroleum or irrigation. He also promotes the use of hugelkultur, which sequesters carbon and eliminates the need for irrigation, and polycultures, which reduces the need for pest control and improves the health of plants. He wrote several articles about lawn care, raising chickens, cast iron and diatomaceous earth. Paul regularly uploads permaculture videos and permaculture podcasts.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
