ＣＯ２等の問題の不安から脱却することが可能となる。The method of the present invention for marine hydropower generation is installed in an area where a ship has been freely navigating, which may hinder the navigation of the ship. It is necessary to make adjustments, but there are the following excellent effects. 1. Ocean currents are movements of seawater caused by solar energy, and there is a constant current of the ocean currents regardless of the weather or season. It is possible to generate power for 24 hours even if the flow velocity or the direction of the flow changes. 2. Because it is natural energy, it does not require a fuel as a power source, does not generate CO 2 and the like, and is clean, permanent and stable energy. 3. If all countries are less dependent on fossil fuels, the number of vessels such as tankers will decrease, and accordingly, the amount of marine pollution caused by transportation accidents and the amount of pollutants dumped into the ocean by tank cleaning of tankers will also decrease. Therefore, it contributes to the prevention of pollution of the ocean where valuable seafood grows. 4. In addition to the Kuroshio, the sea currents around Japan are abundant in renewable energy, with the Oyashio current from the north and various ocean currents, although the current velocity is slightly lower. While promoting energy conservation, if to be actively introducing the ocean current power generation in the near future, it is possible to break away from the anxiety of fossil fuel depletion and CO 2 or the like of the problem.

The current and power generation of the ocean current are expressed by the following formulas based on the momentum theory of hydraulics. F = ρAV 2 where, F: force N (Newton) [rho: density of sea water kg / m 3 V: flow velocity m / s A: area of the blade plate hydraulic turbine m 2 W: density of power generation Nm / s Therefore, seawater Is 1,021 kg / m 3 , the flow rate of the sea current is 1 m per second (2 knots), and the power generation amount when the area of the blade of the water turbine is 7 m 2 is about 4 kW (when the efficiency is 60%). Is increased to the square of the flow velocity. That is, the above-mentioned width 60 m and length 360 m
The power generation system structure boat of the scale has 360 water turbines installed, and the amount of power generation is about 1,440 kW when the flow rate of the ocean current is 1 m per second, and about 5,440 kW when the flow rate is 2 m per second.

If six power generation system-structured boats are arranged, the total power generation is about 50,000 kW and the flow rate is 2 m / s when the flow rate is 1 m / s.
In the case of m, it becomes about 200,000 kw. By the way, the current of the Kuroshio differs slightly depending on the sea area and season, but it is 0.5 to 2.0 per second throughout the year.

It is possible to generate power for 24 hours even if the flow velocity or the direction of the flow changes. 3, because it is natural energy is not required fuel as a power source, occurrence of CO 2 is not a stable energy clean permanent. 4. If the reliance on fossil fuels is reduced in all countries, the number of vessels such as tankers will decrease, which will also reduce the amount of marine pollution caused by transportation accidents and the amount of pollutants dumped into the ocean by tank cleaning of tankers. Therefore, it contributes to the prevention of pollution of the ocean where valuable seafood grows. 5. In addition to the Kuroshio, the currents near the Japan Sea are slightly inferior to the Kuroshio, but the Oyashio Current from the north and various ocean currents are present and are rich in natural energy. While promoting energy conservation, if to be actively introducing the ocean current power generation in the near future, it is possible to break away from the anxiety of fossil fuel depletion and CO 2 or the like of the problem.
