What is a solar cooker easy definition?

A solar cooker, or solar oven, is a device which uses the energy of sunlight to heat food or drink to cook it or sterilize it. High-tech versions, for example electric ovens powered by solar cells, are possible, and have some advantages such as being able to work in diffuse light.

What is the solar cooker answer?

What is solar cooker? Explanation: Solar cookers are devices that use direct sunlight to produce heat and cook food. Solar dryers are devices that use solar energy to dry substances. Devices that use solar energy to evaporate water and collect its condensate within the same closed system are called solar stills.

What is a solar cooker Class 7?

We use a solar cooker for cooking the food by using the energy radiated by the Sun. Solar cooker works on the principle that sunlight warms the pot, which is used for cooking the food. The process by which the interaction between the light energy and the receiver material turns light to heat is called conduction.

What are benefits of using solar cooker?

Advantages of a solar cooker No requirement of cooking gas or kerosene, electricity, coal or wood. No need to spend on fuel, as solar energy is available free. Food cooked in solar cooker is nutritious. Solar cooking is pollution free and safe. Solar cookers come in various sizes.

What are the 3 types of solar cookers?

Basically, there are 3 types of solar cookers: Box cookers. Panel cookers. Parabolic cookers.

Where are solar cookers used?

It is possible to solar cook on the pacific shores of Chile, Peru and Costa Rica, as well as the deserts of Australia, Saudi Arabia and Iraq. The United States have solar cooks in all of the states, who use the sun to cook their food on a regular basis.

How efficient is solar cooker?

The solar cooker energy efficiency found in range between “0.11–7%” and exergy efficiency found in range between 2.1 × 102 – 7.6 × 102%. These low efficiencies are in agreement with literature [13,30]. The rise and fall of the efficiency was due to equilibrium between pipe temperature and ambient temperature.
