Nanogenerators: producing electricity from sea waves

A team of Chinese scientists developed a device made of nanogenerators that could produce significant electricity from sea waves.

The invention consists of a spring-like coil inside a cylinder.  As the waves push the cylinder back and forth, the separate parts of the spiral come together and separate, generating a small but significant current.  So far, the device has produced up to 347 watts of power per cubic meter, double the best previously achieved record.  It’s also 30 times more than similar devices. 

The development is crucial as wave energy is one of the world’s most highly anticipated renewable energy sources.  The waves are constantly moving to a certain degree.  Therefore, if a device could harness even its most minor movements, it could be a game changer in our renewable future.
