In a bit of technical wizardry, students from the University of Adelaide, Australia, have devised and built an electric diwheel, that with modification, could possibly solve inner city transportation problems. The team, comprised of 14 mechanical engineering students, has taken the idea of a diwheel and quite literally, turned it on its head, and in the process have created a vehicle that could be used to safely transport people around; all with a minimum amount of energy.

Medical ethicist Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally - or to control the next steps of human evolution, using genetic modification, to make ourselves smarter, faster, better. Neo-evolution is within our grasp. What will we do with it?

The Deakin University invention uses waste heat to reduce friction by warming the engine oil. A prototype has been built and tested and the inventors are now talking to the car manufacturers and developing an aftermarket conversion kit. The system, which can be retrofitted, works by diverting waste heat to bring engine oil up to its optimal operating temperature. It was developed by researchers at Deakin University led by Mr Frank Will of the School of Engineering during his PhD project.
