Harnessing the Power of the Ocean: Wave, Tidal, and Thermal Energy
TLDR The ocean holds immense potential as a source of energy, with wave converters, tidal dams, and ocean thermal energy conversion (OTEC) systems being some of the methods to capture this energy. While ocean energy has the ability to power the entire planet and generate three times more energy than wind power, there are concerns about its impact on marine life, water purity, and the environment.
Timestamped Summary
00:00
The podcast episode discusses the potential of using the ocean as a source of energy.
03:53
The ocean can be used as a source of energy through capturing the mechanical energy of wave motion, heat energy from the ocean, and the energy of the tide and currents.
07:48
The kinetic energy of waves can be captured through wave converters, and tides are caused by the gravitational force of the moon, with only about 40 sites around the world suitable for generating electricity from tidal energy.
11:24
The Bay of Fundy generates only 20 megawatts of power despite the enormous transfer of seawater, and one way to generate power from tides is through tidal dams that use turbines to create electricity.
15:21
Ocean thermal energy conversion (OTEC) systems, both closed and open cycle, have the potential to produce fresh water as a byproduct, with a single two megawatt Otec plant capable of producing 4,300 cubic meters of desalinated water every day, although currently Otec systems are not producing a lot of electricity.
19:12
Ocean energy, specifically wave energy, has the potential to power the entire planet with just 0.2% of the energy found in ocean waves.
22:55
Ocean power has the potential to generate three times the amount of energy compared to wind power, but there are concerns about the impact on marine life and the environment.
26:54
Wave energy converters like Salter's Duck have the potential to harness wave power, but there are concerns about the impact on water purity and the potential for earthquakes caused by dams.
