Chinese Researcher Designs Wave Energy Nets
Catch wave power in floating nets; Zhong Lin Wang proposes a radically different way to harvest renewable energy from the ocean using nanogenerator networks.
Zhong Lin Wang, 8 February 2017 (Nature)
“…[O]ceans cover about 70% of Earth’s surface. Wave energy is plentiful day and night…Capturing it requires little land and raises few safety or security concerns. Yet hardly any of this ‘blue energy’ is being generated…No commercial wave farms currently exist…The reason is mainly technological. Today’s wave-energy collectors are..expensive and technically difficult…More fundamentally, waves involve [challenging conditions, including] slow flows and oscillations in random directions…[My research group has] found that collecting electricity from friction is more efficient and cheaper than from alternatives…[To capture wave energy, ‘triboelectric nanogenerators’ need to be incorporated into watertight floats…Power is generated according to how fast the nanogenerator moves with the waves…[In theory, a] square kilometre could generate enough electricity for a town…” click here for more
