The diagram below shows the production of electricity using a system called Ocean Thermal Energy Conversion (OTEC).

The diagram below shows the production of electricity using a system called Ocean Thermal Energy Conversion (OTEC). Q1mL
The diagram illustrates how to produce electricity by using the OTEC system. It can be seen that creating energy are divided into two sections: warm seawater and cold seawater. While the former is producing drink water, the latter are going to be waste saltwater. To start with, solar energy assists to convert warm seawater into water vapour. Then, the drops of water evacuated in the evaporation chamber before travelling through the turbine which creates electricity. Steam is continuing into the tube toward condensing chamber which makes it water for drink purposes. With regards to the cold water, between 29 C and 5 C under 1000 m of sea, it is cycling around the condensing chamber and mixes with the rest of the salt that has been coming from the steam stage. Last but not least, the stream is going to be produced as waste saltwater.
