Chinese scientists have built and tested a floating droplet electricity generator (DEG) to turn the kinetic energy of raindrops into renewable power. Unlike conventional DEGs, which are used on land and are heavier and costlier, the floating device developed by researchers at the Nanjing University of Aeronautics and Astronautics (NUAA), with the support of Chinese state and provincial funding and programs, uses water for both structural and electric-generation components. In the research, published in the November issue of National Science Review,…
