11: Michael Mobbs – Saving The Rain

The ongoing bushfires in south-eastern Australia are a horrible reminder that we need to change the way we’re operating. But I don’t think it’s a simple as trying to reduce carbon emissions. So over the next few weeks, I’m going to talk to some people who have ideas about more tangible and effective ways of managing landscapes, including urban areas, farms and bushland. If we don’t re-instate a functioning water cycle, then things are going to get worse, no matter how much CO2 is in the air. This interview is with Michael Mobbs. Michael is a former environmental lawyer from Sydney who has become known as the “off-grid guy”. Because, in 1996, he began the process of disconnecting his inner-city home in Sydney from mains water, sewage and electricity.

An example of the gutters Michael describes: https://www.eaveswatersystem.com/ 12:15 Bureaucracies never change 12:15 “If you wanted to set up a society, a culture, that’s doomed to fail, this is the one you would set up.” 13:49 People shouldn’t rely on governments. Do what you can, including catching and using as much rainwater as possible. 14:10 Leaky drains: Michael’s street saves 4 million L of water each year from going to the ocean. Here is a great video he made that shows you how to do it: https://www.sustainablehouse.com.au/community-gardens 16:51 A road garden in Bondi 17:57 Food waste and wasted water 18:57 Buy from farmers’ markets 19:25 Michael’s new project to design a pre-fabricated studio house with attached water treatment and solar electricity systems: contact Michael to learn more https://www.sustainablehouse.com.au/contact 21:13 How the house is resistant to bushfires 21:52 Using recycled timber, eg from “weed” species like camphor laurel 23:01 Michael’s recent travels through many areas in rural Australia 24:30 Do an experiment to catch for one day all the water that you would have normally let drain down the kitchen sink: it will be a lot 25:28 Drinking rainwater: it’s healthy and doesn’t have chlorine, which may be carcinogenic 27:05 In Australia, water utility companies are government-owned, so there is no competition. And the government does not fund research into the effects of chlorine on, for eg, gut health 27:53 Michael’s two books, Sustainable House and Sustainable Food: https://www.sustainablehouse.com.au/products 29:17 Archimedes, Newtown, Einstein: they came upon their insights through their interactions with the world around them 29:40 “The best university, the best reading, is where we walk and talk and see in our own environment, wherever that may be, each day.”
