27jun18-- OIST -- Okinawa Institute of Science and Technology Graduate University : Okinawa, Japan. The Wave Energy project, which is kindly supported by Holiday Inn Resort Kandooma Maldives, will test prototype WEC-units (Wave Energy Converter) on Kandooma island. The red arrow marks the experimental site location, where the stable swells are arriving from the Indian Ocean in a southeasterly direction. EnJoy EnJoy
I suggest changing the position of the camera so we can see more than just the waves.
