Explain the principles and working of solar cooker. Also highlight its features over conventional cooker.
Principles and Working of Solar Cooker:
A solar cooker is a device that uses sunlight as its energy source to cook food. It harnesses the solar energy and converts it into heat energy, which is used for cooking. The basic principles and components of a solar cooker are:
1. Solar Collector: The most crucial part of a solar cooker is the solar collector, which gathers and concentrates sunlight onto a cooking vessel. This can be done using reflective materials such as mirrors or reflective panels.
2. Insulation: The cooking vessel is often enclosed in a well-insulated box to minimize heat loss.
3. Absorption: The cooking vessel itself absorbs the concentrated sunlight and converts it into heat, which cooks the food.
Types of Solar Cookers:
