America's 1970's Ocean Energy innovation! (Hawaii, Lockheed, Alfa Laval Thermal & Dillingham Corp.)
Mini OTEC was deployed in July, 1979, and became the first successful at-sea OTEC plant the following month by producing net OTEC power. In the following year, the National Society of Professional Engineers awarded Mini-OTEC as being one of the ten outstanding engineering achievements of that year in the United States.#

Deep Pipelines for Ocean Thermal Energy Conversion...
Interesting story (below video) by Michael Giberson; who explains what slowed this technology in America... And (further below) The strides toward a more affordable (and larger scale) technology within the Int'l community.
The 79' hook up created a successful OTEC demonstration. The technology was there, and the ocean thermal energy conversion system worked as designed...

Ocean thermal power systems back under development Story.
Michael Giberson writes:
"Geothermal power generators use temperature differences between the surface and areas deeper in the earth to move a gas or liquid through a loop and drive a turbine." (One example is the Chena Geothermal Power Plant in Alaska. See the related project at the Chena Hot Springs Aurora Ice Museum, which uses 165°F water from geothermal well to help keep ice museum cold.)
"Ocean thermal power systems work on similar principles, but, to state the obvious difference, underwater rather than underground. A story in the LaCrosse Tribune (Wisconsin) discusses work by an 80-year old Wisconsin engineer who obtained some patents on related inventions in the early 1980s, but saw interest in ocean thermal generation drop off as energy prices fell."
