Question

In solar ponds constructed in Israel, the Sun's energy is concentrated near the bottom of a salty pond. With the proper layering of salt in the water, convection is prevented, and temperatures of $100^{\circ} \mathrm{C}$ may be reached. Can you estimate the maximum efficiency with which useful energy can be extracted from the pond?

Step 1

The bottom of the pond reaches a temperature of $ T_{\text{hot}} = 100^{\circ} \mathrm{C} $. Convert this temperature to Kelvin: \[ T_{\text{hot}} = 100 + 273.15 = 373.15 \, \text{K} \] Show more…
