Japan tests electricity generation using ocean currents

According to NHK television channel, Japan has, for the first time, successfully tested a new system of equipment to produce electricity using ocean currents.

TV news reported that the test was conducted from August 14 in the area of ​​Kagoshima Island in the southwest of the country, where the warm Kuroshio current flows strongly.

The Kuroshio Current or Japan Current is an ocean current in the Western Pacific Ocean off the east coast of Taiwan that flows northeastward past Japan, where it joins the eastward flow of the North Pacific Current.

Thiết bị đã được dìm xuống độ sâu từ 20 đến 50m, với công suất điện tối đa là 30kW.
The device was submerged to a depth of 20 to 50m, with a maximum electrical output of 30kW.

The Kuroshio Current is similar to the Gulf Stream in the Atlantic Ocean, which transports warm tropical ocean water northward toward the poles. It is sometimes called the "black current" - a reference to the word kuroshio, meaning black, and the deep blue color of the ocean water there.

The system was jointly developed by IHI Corporation and the New Energy and Industrial Technology Development Organization (NEDO). The system consists of three metal cylinders, each nearly 20 meters long. Two cylinders are equipped with generators on both sides with 11 meter diameter propellers.

During testing, the device was submerged to depths of 20 to 50m, with a maximum electrical output of 30kW.

According to the developers, this is the world's first successful test of a power generation system using underground ocean currents.
