  • Description

    BACKGROUND: The Naval Undersea Centre in San Diego, California, is operating an experimental "marine energy farm" where giant California kelp, one of the fastest growing plants nurtured and harvested underwater.

    The goal of the project os to learn how to, and demonstrate the ability to utilize solar energy to grow a "crop" underwater.

    There is concern as to whether or not the earth's arable land will be able to produce energy food for the population 30 to 40 years from now. "Wet farming"is being explored as an alternative to conventional framing methods.

    The first problem in "wet farming"is: natural bottom is too far down in most places to allow sunlight to reach it. This was solved by construction of an underwater raft, 40 to 80 feet below the surface, on which the seaweed is planted.

    The second problem involves the almost total absence of nutrients in the upper layers of open sea water. Naval Undersea Centre feels this can be overcome by extending vertical pipes to the bottom from the surface zone to produce an artificial up-wheeling of the nutrient-rich deep water.

    Products which can be produced from kelp include: food for people, livestock and sea animals; methane gas; ethanol; light oils; paper; pharmaceutical; fertilizers and industrial chemicals.

    The test unit is now in place about 1,000 yards off San Clemente Island, California.
