Biofouling prevention causes heavy deposit problems
NIOT of India are apparently experiencing heavy deposit problems in the (cold?) water pipe based on the biofouling prevention they are using, NaOcl Sodium Hypocholorite.

Question to the reader: I have read about other biofouling methods suggested/used in previous OTEC projects, but I can't remember what they are. Do you remember? If so tell us: editor@OTECnews.org

Indian ocean islands interested in OTEC
According to an article from last year in the Indian publication Business Line, Dr. Harsh K. Gupta, The Secretary, Union Department of Ocean Development (DoD), said that Mauritius, Seychelles and Maldives have sought India's expertise in the setting up of ocean thermal energy conversion (OTEC) plants.

These island nations would be perfect users of OTEC technology. The islands are sitting in the middle of a huge energy resource in shape of the ocean surrounding them. They typically have a shortage of foreign currency, much of which is used to import oil, petrol, etc. to drive fossile fuel electricity generators, often in very small and inefficient generators. Furthermore, they are often importers of fresh water for their tourist industry. Both energy and fresh water shortages are easily solved with OTEC plants without destroying the fantastic beauty of the nature in and around these island nations.

OTEC based power for ocean nitrogen fertilisation
Engineering students from The University of Sydney have devised a scheme to produce reactive nitrogen for fertilization of the ocean from an OTEC plant. They claim that "Each floating structure could stimulate the growth of 370,000 tonnes of sardines a year, enough protein for three million people, at a cost of $US400 a tonne, or eight cents per person per day." The University of Sydney News has a recent article about it and also one from January.
