Definitions
- the present invention relates to a device for recovering the energy of waves on a body of water, such as at sea.
- energy consumption is mainly based on non-renewable energies such as oil, gas, coal and nuclear power.
- non-renewable energies such as oil, gas, coal and nuclear power.
- one solution is to use the energy from the sea, more precisely in terms of currents, swell or tide.
- wave energy is only a particular form of solar energy.
- the sun heats unevenly the different atmospheric layers which causes air currents (winds) themselves responsible by friction of the movements that animate the surface of the sea (currents, waves, waves).
- the waves created by the wind on the surface of the seas and oceans carry energy. When they arrive on a floating or coastal obstacle, they can give up some of this energy, which can be transformed into electric current. This is where the winds are the strongest, between 40 ° and 60 ° of latitude, that the power of the waves is maximum.
- wave energy has a very high power potential.
- the average power transported by the waves is given in kW per linear meter. It is proportional to the wave period (the time that separates the arrival of two successive wave peaks) and to the square of the height of the wave (distance between the hollow and the ridge). For example, this potential is 63 kW / m off Ouelich, 50 kW / m on the Atlantic coast and 8 kW / m in the Mediterranean.
- Wave energy is also characterized by the energy that occurs during a year over a linear meter of installation. For example, on the French Atlantic coast this potential is 420 MWh / m. On 1000 km of Atlantic coast the annual energy transported by waves is 420 TWh, it is the order of magnitude of the total electrical energy consumed in France each year.
- the former use wave breaking, the latter use sea-level variations during the passage of waves.
- the former are easy to build and maintain, but their performance is not as good as offshore devices that exploit more powerful and more consistent waves.
