The diagram below shows the production of electricity using a system called Ocean Thermal Energy Conversion (OTEC).
Write a report for a university lecturer describing the information below.
The given diagram highlights various stages involved in the power production with the Ocean Thermal Energy Conversion.
Overall, it is a complicated process, which requires special machinery. In addition, drinking water is obtained as a side product of this process.
Before the process begins, the Sun warms the upper part of the natural water tank with salted water. Before entering the system, the water is warmed to 29 degrees on the top, in comparison of 5 degrees on the depth of 1 kilometer. Then, using separate pipes on different levels, hot and cold seawater is transported to the evacuated evaporation chamber and the condensing chamber, respectively. In the first chamber, warm water is separated to vape, that moves turbines and creates energy, and salt that is then moved to the condensing chamber, where it is mixed with cold water from outside. The vape, after moving a turbine, goes to the internals of condensing chamber, where the rest of the water cools it, producing pure water.
