Georgia Tech prototype triboelectric nanogenerator could extract energy from ocean waves

Green Car Congress

Researchers at Georgia Tech have developed an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy from ocean waves by making use of contact electrification between a patterned plastic nanoarray and water. A report on their work is published in the journal Angewandte Chemie. —Lin et al.
