Dr. Patrick Takahashi is a retired engineering professor who has been advocating for the Blue Revolution for a third of a century.  In 1979 he wrote the original legislation for ocean thermal energy conversion (OTEC) when he worked in the U.S. Senate.

Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep water and warmer surface-level water to run a heat engine to produce useful work, usually in the form of electricity. Fresh water is a byproduct of this process.

You can also bring nutrients that have sunk to the deeper waters closer to the surface where they become pre-fertilizer for a seaweed farm.

This one technology can produce food, energy, fresh water, and hydrogen fuel– everything a floating city in the ocean needs. And OTEC plants will improve the quality of the ocean, and potentially lower the temperature of the water, which prevents hurricanes.

Cultivating food that is lower on the trophic level requires fewer resources and preserves the environment. Dr. Takahashi recommends farming whale sharks because they provide plentiful meat, reproduce quickly, and are lower on the trophic chain than more popular fish like tuna.
