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 diagram depicts the process of generating energy from saltwater using the Ocean Thermal Energy Conversion system (OTEC). It also explains how the same procedure is used to obtain pure drinking water.
Overall, there are three steps to this system: solar energy, evaporation chamber, and condensing chamber. Furthermore, the water is used to maintain the temperature difference up to 1000 metres deep in the sea, which aids in the evaporation and condensation processes.
The evaporation chamber is first filled with sea surface water that has been heated to 29 degrees Celsius by the sun. Salt particles are removed at this point, and the water is evaporated before passing through a turbine. The turbine generates energy by moving water vapour through it.
These vapours then proceed down the pipe into a condensing chamber, where they are continuously cooled by the deep saltwater that circulates through the chamber. Finally, this chamber produces pure drinking water, while the salt is emptied back into the sea.
Sample 2 The Diagram below Shows the Production of Electricity Using a System Called Ocean Thermal Energy Conversion (Otec)
The illustration shows how Ocean thermal energy conversion works and the production of potable water.
The water is processed in two ways. Firstly, the water present on the surface of seawater which is approximately 29 degrees celsius, is warmed by solar energy and converted into water vapours. These warm vapours are passed onto an evaporation chamber in which salt is drained out from the system as pure saltwater. At the same time, the saltless water vapours are passed through the turbine for the generation of electricity. Some water from the turbine is passed to the condensation chamber. After condensing, the water is fit for drinking.
Secondly, the cold water, 1000 m below the surface water, is 5 degrees celsius. It is saltwater and mixed with condensed saltwater and dismissed as waste saltwater, and the cycle continues.
