BioPower Systems

It isn't uncommon to see a large fish move through tail undulations.

Animals using this type of motion are often high-speed, long-distance swimmers.

Australian start-up BioPower Systems mimics that movement to generate power from tidal currents. The energy transferred from a computerized 'fin' is then converted into electricity.
