More specifically, the present invention is provided with a piston unit for supplying seawater by wave force and a rotary seawater compression unit rotated by algae and currents to supply seawater at the same time, so that seawater can be efficiently supplied regardless of non-uniformity of digging. The present invention relates to algae, ocean currents, and seawater compressors using wave power that are implemented in a non-powered and semi-permanently manner.

Korea currently has the highest energy source unit (consumption energy per gross domestic product) in the world, and the dependence on energy abroad is 97% of total consumption (September 20, 2004), and most of them are from fossil fuels and nuclear power generation. will be. Renewable energy is only less than 2% of total consumption. As such, the necessity for the use of energy in consideration of the current environment is rapidly emerging, and the development of renewable energy is not an option but an essential situation.

Ocean wave energy for this purpose can be said to be infinite clean energy that is not depleted even if used together with solar energy. In addition, research on the extraction of available energy has been conducted for a long time due to the great expectation as an alternative energy source for the future of mankind, and wave energy, which is the ocean wave energy, has many advantages. have.

More specifically, among the existing power generation systems, the most efficient power generation system is aberration power generation. The aberration power generation converts the potential energy of water, that is, water head difference × flow rate into electrical energy with an efficiency of 95% or more using aberrations (Francis aberration, Felton aberration, etc.). However, it is difficult to secure potential energy with predictability and sustainability, which lowers operating efficiency and costs a lot such as dam construction costs.

The wave power for this can be said to be an infinite clean energy that is not depleted, and researches on available energy extraction methods have been conducted for a long time with great expectation as an alternative energy source for human future. In addition, wave energy is one of the greenest ways to generate power, and offshore wave energy generation is not in my backyard, which is difficult for many energy supply projects, especially nuclear power. Power plants, etc., tend to oppose citizens coming near their homes.

The wave energy generator is installed far enough from the coast, and the wave energy is more predictable than the solar or wind energy and can be delivered by the electric grid, which is profitable. In addition, the strength of wave energy is that it has a high power density, and it is easier and cheaper to integrate wave power including wind energy existing in the ocean.
