A new kind of wave power could be ushered in by a smart way of putting together lots of nanogenerators that exploit static electricity to generate a current.
Because the current generated by each nanogenerator is low, for wave power, the idea is to link thousands of triboelectric nanogenerators together in long chains linked by flexible connectors. At present, many wave power designs consist of spheres that roll around inside each nanogenerator.
Now, a team led by Zhong Lin Wang at the Beijing Institute of Nanoenergy and Nanosystems in China, who created the first working triboelectric nanogenerator in 2012, has created a different design for wave power, consisting of a spring-like coil inside a cylinder. As the cylinder rocks back and forth in waves, different parts of the spiral touch and separate, generating a current.
In labs tests, this device produced up to 347 watts of power per cubic metre, double the best previously achieved and up to 30 times as much as other triboelectric designs.“The group achieved a significant breakthrough in developing a new triboelectric structure that provides large power density,” says Ventura.
With triboelectric nanogenerators, the structure used to generate power is usually much larger than the thin layer of the triboelectrics, he says. “If you can pack more in the same space, you get major advantages.” The work overcomes some of the major roadblocks preventing the deployment of triboelectric nanogenerators for wave energy harvesting, says Ventura.at the University of Edinburgh, UK, isn’t convinced that triboelectric nanogenerators could outperform conventional wave power designs. What’s more, because the process involves friction, wear is going to be an issue, says Salter, and the team doesn’t say how it will address this.
