| - Assume the Dish-Stirling-System were equipped with a solar tracker collecting the direct normal component. What is the approximate(!) insolation (energy, cumulative irradiance) per year in Almería (Spain) per 1 m² of solar collector? Read it from the diagrams above. The rough value ranges given by the color scale are sufficient for a rough estimate. | - Assume the Dish-Stirling-System were equipped with a solar tracker collecting the direct normal component.

| - The efficiency of an ideal Carnot machine depends on the two temperatures $T_c$ and $T_h$. Draw the efficiency as a function of $T_h$ (from 400K to 850K). Of course, it is not linearly dependent on temperature. This means, if you double the temperature difference you are not doubling the efficiency. | - The efficiency of an ideal Carnot machine depends on the two temperatures $T_c$ and $T_h$.

| - | - Assume simply average annual conditions. You do not have to take irradiance variations (day time, season, weather) into account. Assume you had a mirrored dish following the sun and assume that the collected power by the dish is completely redirected to the hot end (the hot reservoir $T_h$) of the Stirling engine. How large has the dish to be (on average) to able to provide $Q_\mathrm{in}$ (on average)? | + | - Assume simply average annual conditions.
