Large whirlpools, caused by the peculiar topography of the region, are the source of these high tidal currents. They are called maelstroms, and when they have a substantial vertical velocity component, they are technically vortexes.

海洋溫差能海洋溫差能No commercial OTEC plant is in operation anywhere in the world.

Hawaii has experimented with OTEC since the 1970s at the Natural Energy Laboratory of Hawaii (NELHA) on Hawaii Island.  It was found to be technically feasible but prohibitively expensive in comparison to oil prices at that time.
