| Seems interesting but the details seem vague. I don't understand how warm ocean water can vaporize in the amounts needed without adding additional energy. Or maybe another liquid is used with a low boiling point? The info from the website seems to indicate the warm ocean water is getting vaporized though. |

Warm surface sea water passes through a heat exchanger, vaporizing a low boiling point working fluid to drive a turbine generator, producing electricity.

But how does evaporating sea water come in to make fresh water? If it's low boiling point for different substance, it won't be hot enough for sea water.
