Yet another open-ocean aquaculture cage, this one designed by Hawaii Oceanic Technology.
Like the Aquapod®, the Oceansphere™ will be untethered to the sea floor and is being marketed as a solution to the continuing rapid decline of wild fish population.
One noteworthy difference is its proposed energy source: the ocean itself. Specifically, the Oceansphere™ will exploit the temperature difference between shallow and deep water through a method called ocean thermal energy conversion (OTEC). The “exclusive patent pending hybrid OTEC power plant,” we are told, will provide “100% of the electricity necessary to geostatically position the 82,500 cubic-meter Oceansphere™.”
