podcast 043 gaia’s garden chapters forward to 3 | | permaculture blogs, podcasts and videos by paul wheatonpermaculture blogs, podcasts and videos by paul wheaton
Paul Wheaton , Jocelyn Campbell , and Dave Bennett read Gaia’s Garden by Toby Hemenway and review it chapter by chapter. The forward talks about creating an ecosystem in a jar, and the preface introduces the “meadow-inspired food garden” in which it is “riotously abundant” and nature does most of the work. For chapter 1, the group discusses working with nature, insects in the garden, Dave shares about his neighbor growing up’s shaman’s garden , monocrop disadvantages, the irony of growing only native plants and relying on non-native food , and focusing on understanding what nature is doing rather than fighting it. For chapter 2, the group briefly talks about the Bullock Brothers Farm , and mature vs. immature ecosystems.La pompe à eau "fluidyne" est une pompe stirling : un coté chaud se dilate, pousse un volume qui franchit un clapet anti-retour, puis est refroidi donc se recompresse, puis est rechaufée donc se redilate etc ... suivant le principe : dont une réalisation est : Une étude complète et détaillée : Fluidyne .PDF

Future firefighters have their work cut out for them. Perhaps nowhere does this hit home harder than in Australia, where in early 2009 a persistent drought, high winds, and record high temperatures set the stage for the worst wildfire in the country’s history. On February 9th, now known as “Black Saturday,” the mercury in Melbourne topped 115 degrees Fahrenheit (46.4 degrees Celsius) as fires burned over 1 million acres in the state of Victoria—destroying more than 2,000 homes and killing more than 170 people, tens of thousands of cattle and sheep, and 1 million native animals. Even as more people move into fire-prone wildlands around the world, the intense droughts and higher temperatures that come with global warming are likely to make fires more frequent and severe in many areas.
