Problems solved by technology

The first difficulty lies in the installation and maintenance of a large pipe with a diameter of 10 meters at a depth of 1000 meters in the face of the turbulent currents often encountered in the ocean.
The second difficulty lies in the inherent inefficiency of the typical system
In the past, biofouling of the entire system has also led to catastrophic failures

Embodiment Construction

[0020] figure 2 A first embodiment of an ocean thermal energy conversion (OTEC) system of the present design, which may include one or more large floating solar collectors 32, is shown. Said solar collectors 32 are designed to heat the water introduced into the warm water inlet 14 to a temperature t exceeding the surface temperature of the adjacent body of water 40 2 . The solar collector 32 can be constructed inexpensively, for example by sewing at least two layers of plastic material to form a floating support for supporting a pipe connected to the warm water inlet 14 . exist figure 2 In the shown embodiment, as in the prior art shown in FIG. 1 , the condenser 20 is maintained at a temperature t due to the supply of cold water pumped up from the cold water inlet 12 by the pump 24. 1 . This higher temperature t of the water entering the warm water inlet 14 2 This translates into a larger temperature change Δt than was present with the prior art discussed in connection wi...

Abstract

An Ocean Thermal Energy Conversion (OTEC) system having a turbine with an upstream side and a downstream side. Warm water under a partial vacuum is converted into a vapor, the vapor being supplied to the upstream side of the turbine at a pressure controlled by the temperature of the warm water. A condenser is situated on the downstream side of the turbine to cause the vapor, after passing through the turbine, to undergo a phase change back to a liquid, which can be used as potable water. The condenser is coupled to a source of a cooling liquid, and the pressure of the vapor on the downstream side of the turbine is determined by the temperature of the cooling liquid. A flexible floating solar collector supplies the warm liquid to the upstream side at a temperature higher than normal ambient temperature.

Description

[0001] Cross References to Related Applications [0002] This application relates to US Provisional Applications Serial Number 61 / 743,236 filed on August 29, 2012 (US Provisional Applications Serial Number 61 / 743,236) and US Provisional Applications Serial Number 61 / 849,927 filed on February 5, 2013 (US Provisional Applications Serial Number 61 / 849,927), and all rights and interests in the above-mentioned U.S. Provisional Patent Application are claimed. Background technique [0003] Ocean Thermal Energy Conversion (OTEC) systems have been studied since the late 1920s and early 1930s, and based on the principle of the "Rankine Cycle" developed in the mid-19th century, small A large-scale ocean thermal energy conversion system was tested. These systems involve a turbine having an upstream side and a downstream side. On the upstream side of the turbine, the warm liquid is converted into a vapor under partial vacuum, and during this process the vapor pressure is controlled by th...
