On the right there is an example of modular design.
It is called the dual dish solar tracker.
The example is a model of the tracker. But what is modular about it? Well every component can be done in a different way and it can still work. For instance, the little ball represents a cooking pot. But it could also be a Stirling engine, or a thermophyle or a water heater or an air heater. Similarly, the dishes can be made to the highest standard for smelting or to a much lower standard for solar cooking. Write the first section of your article here.

Low tech yet educational!Edit
This little model can be used to explain a lot about how the earth moves round the sun, why the sun shines longer in summer, etc.
