Chapter 5: How to deal with a lack of warm food?

In the event of a flood, hurricane or other natural disaster, we may lose access to electricity and gas. In such conditions, we cannot prepare a warm meal. How to deal with this? We can use the energy of the sun and prepare a meal in a solar cooker.

In the photographs you can see how our solar cooker was made. To prepare it, we used a cardboard box, aluminum foil and a plastic plate. The reflective, flat surface focused sunlight. We painted the bottom of the box black so that it absorbs solar energy.

We put a broken, raw egg inside and covered it with a transparent plate that retained heat inside. As a result, the temperature inside has risen to over 40 degrees C. At this temperature, protein denaturation begins. Egg white and egg yolk left in the oven were seen to be changing.
