1. warm seawater -> solar energy, evacuated evaporation chamber -> water vapour and salt
2. water vapour -> turbine -> electricity
3. water vapour -> condensing chamber, cold seawater -> drinking water
4. salt -> cold seawater -> waste salt water -> ocean -> repeat the process

Opening

The diagram illustrates how to generate electricity and create drinking water by using a system called Ocean Thermal Energy Conversion (OTEC).

Overview

Overall, it is clear that the Ocean Thermal Energy Conversion system has three main components namely an evacuated evaporation chamber, a turbine and a condensing chamber. It operates by converting heat energy into electricity.

Body

At the first stage in the production of electricity, warm seawater is heated by solar energy and then flows into the evacuated evaporation chamber. In the chamber, salt is deposited (lắng đọng) and water vapour is emitted.

Next, this vapour then drives a turbine to generate electricity.

At the third stage of the process, the water vapour enters the condensing chamber and is condensed to produce drinking water thanks to the low temperature (about 5 degrees Celsius) of the cold seawater.

Meanwhile, the salt produced by the system is poured into the cold seawater, and becomes waste salt water which is then discharged into the ocean and the process can be repeated.
