A week in the maelstrom of Brisbane, crisscrossing the city by bike, car, van and truck. I joined the pickup and delivery runs of two organisations rescuing food waste, and a third tackling food miles. I also visited two research institutes developing alternatives for liquid fuels: hydrogen from solar-powered electrolysis, and biofuels from algae.

Many thanks to my wonderful hosts, Trevor and Sue, who have the first registered solar power station in Qld on their roof, and Gemma, Enton and David.
