Abstract
In order to bring cold water from the depths of a body of water, a long pipe is extended into the body of water. Arrangements are provided for pumping the water out of the pipe. A nozzle is then provided to direct a stream of water up through the pipe at high velocities, without touching the walls thereof, based on the high pressure of the water at the lower end of the pipe. At the top of the pipe near the surface of the body of water, arrangements are provided for collecting the cold water drawn from below. This ballistic cold water pipe may be employed to economically provide cold water for ocean thermal energy conversion (OTEC) systems, and for other purposes.
