Thanks to OIST for sponsoring this video. To learn more, visit https://admissions.oist.jp/ Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. ___________________________________________ To learn more, start your googling with these keywords: Wave energy converter - a device for turning the mechanical energy of ocean waves into mechanical energy (flow of a substance) or electrical energy Oscillating water column - an open-bottomed chamber filled with air and water, whose wave action moves the water column up and down like a piston, forcing the air out past a turbine Attenuator - a long multisegment floating structure oriented parallel to the direction waves travel, where differing heights of waves along the length of the device flex the connections driving hydraulic pumps that can be connected to turbines Oscillating body - a floating buoy that oscillates with waves, generating electricity within the buoy or by pulling on a generator or by pumping water through a turbine Overtopping device - a reservoir filled by waves to a height higher the average nearby ocean, into which reservoir water is released, spinning a turbine Biofouling - undesirable growth of organisms like barnacles and algae on underwater surfaces Ocean wave - energy passing through water and causing it to move in a circular motion Turbine - a machine for producing continuous power in which a wheel with blades gets hit by a fast-moving flow of water, steam, gas, air, or other fluid, and spins (often connected to a magnet that spins) Induction - the production of an electric current in a wire by movement of a nearby magnetic field ___________________________________________ If you liked this week’s video, you might also like: Why Wave Power Has Lagged Far Behind as Energy Source https://e360.yale.edu/features/why_wave_power_has_lagged_far_behind_as_energy_source _________________________________________ Subscribe to MinuteEarth on YouTube: http://goo.gl/EpIDGd Support us on Patreon: https://goo.gl/ZVgLQZ And visit our website: https://www.minuteearth.com/ Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC And download our videos on itunes: https://goo.gl/sfwS6n ___________________________________________ Credits: Script Writer & Narrator: Alex Reich Video Illustrator: Arcadi Garcia Rius Video Directors: David Goldenberg & Julián Gómez With Contributions From: Henry Reich, Kate Yoshida, Ever Salazar, Peter Reich, David Goldenberg Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder ___________________________________________ References: Aderinto, T., & Li, H. 2018.
