Patent ID: 8740499

Claim:
A method for utilising the current in a large body of water, including an ocean to raise water from a lower region of the body of water, containing colder more nutrient rich water, to an upper region of the body of water, containing warmer less nutrient rich water, comprising the steps of: (a) submersing a conduit into the body of water, the conduit including a lower end having a lower opening and an upper end having an upper opening, such that the lower opening is in the lower region and the upper opening is in the upper region; (b) anchoring the lower opening in place against movement by the current; (c) maintaining the upper opening downstream from the lower opening so that the conduit is angled from the vertical in a direction downstream from the lower opening wherein the conduit is oriented in a direction with the current and the lower opening is oriented in a generally vertical plane wherein the maintaining is undertaken by utilising the current to maintain the upper opening downstream of the lower opening; (d) utilizing the current to direct the water into the lower opening to flow upwards through the conduit and out the upper opening; and wherein the cross-sectional area of the lower opening is greater than the cross-sectional area of the upper opening.
