Difference between Tides and Waves. Key Difference: Tides are the rise and fall of sea level that is caused by the gravitational pull of the moon and the sun on the Earth. Waves are actually energy that moves across the surface of the water.
It is the ocean swell waves that are the best form of wave for Oceanlinx technology. Wave energy is not to be mistaken for tidal energy. Tides are caused by the gravitational pull of the moon and sun, and have a period of around 12 hours, whereas ocean waves have a period of around 10 seconds. Due to these vast differences the technology required to extract this energy is extremely different.
