  4. Radiant heat, or energy of radiation.

ocean thermal energy conversion (OTEC) (s) (noun) (no pl)
One of the various techniques for extracting energy from the vertical temperature difference in the oceans: In principle, ocean thermal energy conversion can be used to generate electricity, desalinate water, support deep-water mariculture, and provide refrigeration and air-conditioning.
ocean thermal gradient (OTG) (s) (noun) (no pl)
The temperature difference between warmer surface waters of the ocean and colder deep waters, whereas the deep waters are about 20-50 degrees Fahrenheit colder that the surface waters: In principle, the ocean thermal gradient can be utilized with various types of ocean thermal energy conversion systems.
