WaveFlyer: The world's first electric hydrofoil jet-ski
The renewable energy vehicle (REV) project at the University of Western Australia has partnered with technology partner Electro.Aero to develop the first hydrofoil watercraft, named WaveFlyer.
The WaveFlyer looks like a conventional jet ski when it is stationary, but rises above the water during operation using an actively stabilized hydrofoil propulsion system. It is much quieter, uses less energy and produces no emissions compared to alternative fuels.
