In search of alternative energy sources, the Japanese company IHI and the governmental organization NEDO conducted several tests on the use of a generator based on the use of ocean currents. After submerging the facility near Kagoshima Prefecture, the equipment produced up to 30 kW of electricity.
The experimental generator was immersed to a depth of 20 to 50 meters in order to find the most effective position. Due to the strong ocean current, the constant rotation of the turbine installation allowed the generator to be launched and stable power supply indicators achieved.
Scientists are sure that this technology is much more stable than the transformation of solar energy. The nature of ocean currents is such that the strength of the water flow does not depend on the time of day, and hence the generator can work with constant efficiency.
Kagoshima Prefecture has chosen non-accidentally. During the research, the scientists found out that the deep currents in this area are stable and have sufficient strength.
Now the project of IHI and NEDO goes into the stage of active development and improvement of equipment. After calculating the cost of production and the profitability of producing such generators, engineers plan to commence commercialization of the project. If successful, the first marine generators will be put into operation as early as 2020.
