Cold, deep seawater brought up by OTEC pipes is nutrient-rich-parasite and free, and can be pumped into onshore ponds producing algae or other products in a controlled system [6]. At NELHA, private companies have already profited from raising lobsters, flounder, and high-protein algae in mariculture ponds fed by the cold water. Additionally, this cold water has been used to grow temperate crops such as strawberries in Hawaii's tropical climate [7]. Air conditioning and industrial cooling may be the most lucrative of all ancillary benefits of OTEC plants. Currently, both of the two main buildings at the NELHA lab are effectively air conditioned by cold seawater pumped through OTEC pipes [8].
