How does wave power generate electricity from a floating object?





Question: How does wave power generate electricity from a floating object?

Answer: All forms of hydrodynamic (water flow) energy resources rely on mechanical motion to drive electrical generators. Magnets moved within copper wiring will produce an electrical charge which is the basis of how all electrical generators work. Wave power harnesses the elliptical motion of objects floating on the surface of a body of water with waves. Not only does the object move up and down but it also moves from side to side first behind pushed by the wave and then “falling” down the other side once the peak has passed. This results in the circular (elliptical) motion. The object (buoy) is connected to an electrical generator usually through cabling that provides the mechanical motion necessary. The generator will be anchored either below the surface of the water or an anchoring system exists solely to keep the system in place and the generator is mounted above water.
