Concept of salt gradient is utilized to store the heat energy in which of the following solar energy collecting systems?
- A.
Solar thermal collectors
- B.
Solar cells
- C.
Solar ponds
- D.
Solar kilns
Attempted by 4 students.
Show answer & explanation
Correct answer: C
Solar ponds utilize a salt gradient to store heat energy. The increasing salinity with depth creates a density barrier that prevents convection, trapping thermal energy in the bottom layer.
