In 2017, Japan tested a twin-turbine machine in the Kuroshio Current; the floating device later showed it could generate 100 kW from the Pacifics river

Japan's innovative Kairyu turbine has achieved a significant milestone by effectively harnessing strong ocean currents to generate electricity. Unlike solar or wind, this solution promises reliable energy production. Prolonged testing has been dedicated to ensuring the systems durability and its potential for commercial use. However, high installation and offshore construction expenses pose serious hurdles that researchers are now striving to overcome through cost and method enhancements.
