Ocean Energy: Harnessing Power from Tides, Waves, and Thermal Gradients

Learn about ocean energy technologies and their potential in this 24-minute lecture from Stanford University's Diana Gragg, Core Lecturer in Civil and Environmental Engineering. Explore the historical development, environmental considerations, and various methods of harnessing ocean power, including tidal energy, ocean currents, wave energy conversion, Ocean Thermal Energy Conversion (OTEC), and salinity gradient systems. Gain insights into the current state and future prospects of ocean energy technologies, their environmental impacts, and their role in the broader energy system. Delve into detailed explanations of different ocean energy capture methods, from flowing kinetic systems that utilize tidal forces and ocean currents to oscillating kinetic systems that harness wave power, thermal energy conversion processes, and chemical energy extraction through salinity gradients.
