Waste heat energy incidental to the generation of electric power, or the power output itself, could be employed to raise nutrient-rich seawater from depth to the surface to enhance the production of animal protein. This water would be maintained near the surface either by thermal buoyancy (in the open sea) or by mechanical forces (in confined parts of the sea). With dissolved phosphorus as the enrichment indicator, fertilization effects are calculated for various biological equilibria in the food chain. These effects could conceivably resultin the per capita addition of animal protein of up to 31 times (in the open sea) and up to 2500 times (in the confined situation) human need, for twice present United States levels of per capita power use.
