An ocean thermal energy conversion power plant built by Makai Ocean Engineering went operational in Hawaii in August 2015. The governor of Hawaii, David Ige, "flipped the switch" to activate the plant. This is the first true closed-cycle ocean Thermal Energy Conversion (OTEC) plant to be connected to a U.S. electrical grid.
As in other open cycle OTEC schemes, the technique involves boiling seawater under low atmospheric pressure. The scheme can take many forms so for illustration a particular form will be described and a section below will list details of alternate forms. The prerequisite for mist lift is that a significant thermal gradient exists.
In the U.S. state of Hawai'i, the Natural Energy Laboratory of Hawaii Authority tested an open-cycle OTEC plant with cogeneration of fresh water and electric energy, using a temperature difference of 20 °C (36 °F) between surface water and water at a depth of around 500 metres (1,600 ft).

U.S. President-elect Donald Trump said "anything can happen" when asked about the chances of going to war with Iran during his next term in an interview with Time, coinciding with his being named ...
Similar to the open cycle in ocean thermal energy conversion (OTEC). The disadvantage of this cycle is the cumbersome problem of a large diameter turbine (75 meters +) operating at below atmospheric pressure to extract the power between the water with less salinity & the water with greater salinity.
