David Warren has been fascinated with batteries since he was a small boy. He has also been a keen sailor for a similar length of time. So, it was probably inevitable that one day he would have an electric-powered boat. About a decade ago, David met Andy Gamlin, who at that time was director of the Wooden Boat Centre, an Australian boatbuilding school in the town of Franklin, Tasmania, just south of Hobart. Both of them were interested in electric boats. David, in fact, had by then advanced his youthful obsession with batteries, and in 2008 he built an electric vehicle, a microlight airplane that he thinks was the first electric aircraft to fly in the southern hemisphere. This was followed by an electric-car conversion and an electric quadcycle he built for a sheep farmer.
