Ocean thermal energy conversion (OTEC) is a system that [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]converts [/bg_collapse]heat energy into the electric power using the temperature difference between surface seawater, which can be up to 29 degrees Celsius, and deep seawater, which is only 5 degrees Celsius.
The main components of the system are an evacuated evaporation chamber, a turbine and a condensing chamber. The solar energy of the sun heats up the surface water and this warm water is [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]introduced[/bg_collapse] into the evacuated evaporation chamber, where it boils. As it boils, salt is [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]deposited [/bg_collapse]and water vapour is [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]generated[/bg_collapse]. This vapour then drives a turbine to generate electricity. After it powers the turbine, the water vapour[bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ] enters[/bg_collapse] the condensing chamber, which is cooled by the water from the depths of the ocean. The water vapour is condensed in this chamber, producing drinking water. Meanwhile, waste salt water is [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]discharged[/bg_collapse] into the ocean and the process can be repeated.

Model answer
The charts show how much local authorities spent on a range of services in Someland in three separate years: 1980, 1990 and 2000.
In all three years, the greatest expenditure was on education. But while K-12 education [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]saw a fall [/bg_collapse]from 25% in 1980 to only 18% of spending in 2000, higher education remained the largest proportion, reaching [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]45%[/bg_collapse] of total spending in 1990 and ending at [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]40%[/bg_collapse] in 2000.
Expenditure on health and human resources had increased to 20% by 1990 before decreasing to only [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]10%[/bg_collapse] by the end of the period. In contrast, the share of transportation saw an opposite trend. This cost decreased to only 6% of total expenditure in 1990 but [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]rose dramatically[/bg_collapse] in 2000 when it represented 22% of the total budget. Similarly, the cost of environmental services saw a rising trend, growing from only 4% to [bg_collapse view=”button-orange” color=”#4a4949″ expand_text=”Show More” collapse_text=”Show Less” ]9%[/bg_collapse] by 2000.
Overall, higher education constituted the largest cost to local authorities, and while spending increased for transportation and environmental services, there were corresponding drops in expenditure on health and human resources and K-12 education.
