Triboelectric-Electromagnetic Hybrid Generator for Harvesting Blue Energy. [PDF]

Nanomicro Lett, 2018
Progress has been developed in harvesting low-frequency and irregular blue energy using a triboelectric-electromagnetic hybrid generator in recent years. However, the design of the high-efficiency, mechanically durable hybrid structure is still challenging. In this study, we report a fully packaged triboelectric-electromagnetic hybrid generator (TEHG),

How ‘Blue’ Is ‘Green’ Energy? [PDF]

Trends in Ecology & Evolution, 2020
Often perceived as environmentally benign, 'green' renewable energy technologies have ecological costs that are often overlooked, especially those occurring below the waterline. After briefly discussing the impacts of hydropower on freshwater and marine organisms, we focus this review on the impacts of marine renewable energy devices (MREDs) on ...
