National GeographicWhat can a whale teach us about renewable energy? A lot. Scientists have found that tubercles—the bumps on a whale's fin—help them swim more easily underwater and thus increase energy efficiency. Using biomimicry, humans applied the same principle to turbine blades and found that it also improved energy efficiency. Watch as host @addi.mov explores the science behind this whale-inspired innovation.
