   - Write a program in Python to be able to re-calculate all calculations easily when changing parameters. The following parameters should be modifiable: Lower and upper volume, lower and upper temperature, number of moles of diatomic working gas.
   - 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.
-  - 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)?
