Plugging into ocean waves with a flexible, seaweed-like generator
Ocean waves can be powerful, containing enough energy to push around sand, pebbles and even boulders during storms. These waves, as well as smaller, more gentle ones, could be tapped as a source of renewable energy. Now, researchers have developed flexible power generators that mimic the way seaweed sways to efficiently convert surface and underwater waves into electricity to power marine-based devices.
