Back on the road. From Melbourne I cycled north into the mountains and against a fierce headwind to Kinglake to visit an ‘Earthship’. Daryl’s home and community were devastated by bushfire, and so his new home will be a self-contained, bushfire-proof bunker made of salvaged timber and glass, mud brick, cob, glass bottles, car tyres and rammed earth, with solar panels, rainwater tanks and a built-in food-producing greenhouse fed by greywater.
