In article number 2001041, Zhen Wen, Jun Zhong, Xuhui Sun and co‐workers develop an automatic high‐efficiency energy collection and conversion system by converting blue energy to chemical energy. A gear‐driven triboelectric nanogenerator is designed to drive a photoelectrochemical cell under sunlight illumination to produce hydrogen. Without sunlight, it can be automatically switched to another working state to charge a Li‐ion battery, which enables effective utilization of clean ocean energy.
