The Tokyo-based company initially planned to start testing the Skwid off the western coast of the southern Japanese island of Kyushu in October 2013.

However, the unexpected sinking of the prototype’s marine turbine component in Japan’s Inland Sea, off the northern coast of Kyushu, forced it to delay its installation plans until 30 October of this year.

The machine — which matches a three-bladed vertical-axis wind turbine (VAWT) with a Savonius ocean-current turbine — is now installed off the coast of Yobuko, Saga prefecture, west of the city of Fukuoka.

Modec has told Recharge that it plans to test the prototype for about a year.
