Nanogenerator Harvests Ocean-Wave Energy

"There seem to be no limits to the ingenious ways that designers are devising to harvest energy or take existing approaches and exploit and enhance them," writes the site Electronic Design:A research team at the Pacific Northwest National Laboratory (PNNL) has developed a contact-separation mode triboelectric nanogenerator (TENG) with a simple structure for harvesting wave energy and powering marine sensors and transmitters.Although this isn't the first cylindrical TENG (C-TENG) — several
