Tapping this humongous amount of energy has been the fascination of many eminent scientists and experts of the world. The ocean power technologies are based on the tried and tested principles of hydrodynamics and electrical engineering.
The ocean water energy is present in the three forms, as said earlier. The tides of the ocean hold a great amount of energy. Imagine the amount of strength that is needed to make the water rise. This strength of the water needs to be captured for its conversion into electricity. The electricity generation from tides is done with the help of turbines. As the tides flow into the blades of the turbine, it makes the generator to turn and generate electricity.
Waves are the other form of ocean energy. The wave energy of the ocean is captured using point absorbers that capture the energy from the surface or from pressure fluctuations below the surface of ocean water.
Ocean’s thermal energy is created when the sun’s heat warms the ocean surface water whereas the water below remains cold. The temperature difference can be used suitable in the generation of electricity using turbines. |
True, true. Aren't they building tidal power stations in the Bay of Fundy?

This one is no different.
As long as there is oil in the earth we are stuck with obsolete internal combustion. If new staff is free energy, forget about it, this is the truth.
Tesla invented wireless power transfer,scalar and electric car long time ago and only now nokia "came up" with wireless phone chargers.
As long as politics are based on making the $ this will never change.

+1. I'm glad I won't be around to see the day when oil runs out... or will I?
