So I blather on for 90 minutes about permaculture, eco building, rocket mass heaters, hugelkultur, raising chickens (and other animals) in a paddock shift system, and lots more. Podcast is something I don't really understand, but the guy says that 20,000 people will listen to this in one day. Yowza. Paul Wheaton from Permies.com on Permaculture, Hugelkultur, Survival Housing and More | The Survival Podcast Maybe people load this sort of thing in their mp3 players and listen to it when they commute or something. Well, if nothing else, I kinda feel like I did an okay job of giving an overview of a lot of permaculture stuff in 90 minutes.
