由于地球表面70%被水覆盖，波浪能非常丰富，有可能成为最环保的电能形式之一。然而，由于缺乏有效的技术，水波能收集作为一种能源几乎是未开发的。在这里，我们报告了一个网络设计的摩擦电纳米发电机（TENG）的大规模收获动能水能源。依靠传统聚合物和非常薄的金属层之间的表面充电效应作为每个TENG的电极，自然漂浮在水面上的TENG网络（TENG-NW）将缓慢，随机和高强度的振荡波能量转化为电能。根据单个TENG的测量输出，TENG-NW预计在1平方公里的表面积上提供1.15兆瓦的平均功率输出。鉴于其引人注目的特点，例如重量轻、极具成本效益、环保、易于实施以及能够漂浮在水面上，TENG-NW为从海洋中大规模采集蓝色能源提供了一种创新且有效的方法。
With 70% of the earth's surface covered with water, wave energy is abundant and has the potential to be one of the most environmentally benign forms of electric energy. However, owing to lack,of effective technology, water wave energy harvesting is almost Unexplored as an energy source. Here, we report a network design made of triboelectric nanogenerators (TENGs) for large-scale harvesting of kinetic water energy. Relying on surface charging effect between the conventional polymers and very thin layer of metal as electrodes for each TENG, the TENG networks (TENG-NW) that naturally float on the water surface convert the slow, random, and high-force oscillatory wave energy into electricity. On the basis of the measured output of a single TENG, the TENG-NW is expected to give an average power output of 1.15 MW from 1 km(2) surface area. Given the compelling features, such as being lightweight, extremely cost-effective, environmentally friendly, easily implemented, and capable of floating on the water surface, the TENG-NW renders an innovative and effective approach toward large-scale blue energy harvesting from the ocean.
