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.
