Cheap power sounds like a wonderfully lofty dream, but an 18-year-old from Rotorua is working to patent something which could achieve just that.
Former John Paul College student Cian Hinton won the environmental engineering category at this year's Taiwan International Science Fair with his Alternating Rotation Converter (ARC) Generator, an electrical generator for a hydro-power station. The fair had 90 students from 21 countries, with 15 projects in his category.
Hinton said his model generated power from water and was a fully functional prototype.
"This is a completely new [design] concept that has not been explored yet and, as an aspiring engineer, this is exactly the sort of thing that I wish to explore."
The success of the final iteration came down to chance: "It just happened to work."
