Harvesting Large-Scale Blue Energy

Abstract

Harvesting water wave energy is a great challenge to traditional electromagnetic generator (EMG) mainly due to its low frequency, large area of distribution, random in amplitude and high cost. This chapter presents how TENG can be an effective technology for harvesting water wave energy by using triboelectric effect and electrostatic induction effect. The high output voltage of TENG makes the harvested energy being effectively useful. A network design is also presented for harvesting ocean energy in general toward the dream of blue energy. The high performance of TENG at low frequency is an unreplaceable and unbeatable advantage in comparison to EMG, making the two technologies complement each other for different applications.
