I've been wanting to write a children's book on sustainability for a while now, (there's not enough) and asked my school teacher friend Liza Mackay to help me. She said why don't I just write my own story, so we did! David's Dream of a Better World is an autobiograhy condensed to 34 self illustrated pages telling the story from a regular inquisitive boy through to owner of the self designed and built Helios Eco Lab, or what some people say, a living museum of sustainability.
