We usually cook our food using liquefied petroleum gas or microwave ovens.
Liquefied petroleum gas is an oil fuel that is becoming more expensive at a very fast rate, while microwave ovens are run by electricity, which is generated by various types of fossil fuels that consume very quickly, it can also cause pollution.
Solar cookers are the safest and cleanest way to cook food.
Solar cookers cook food using solar energy, which is very rich and free.
Solar cookers do not require any other fuel and can be exposed to the Sun anywhere in the outdoor atmosphere.
When the food is to be cooked, it must be kept only in a solar cooker.
You don\'t have to pay close attention to it, and when the food is cooked in a solar cooker, you can easily do other work.
The components of the solar cooker and its working solar cooker have various shapes and sizes and have different types of solar collectors.
A typical solar cooker is a box containing raw food that can be kept inside.
The top of the box is a mirror and the sun falls on it.
They are reflected and concentrated in a small area of the box where cooking utensils are stored.
The food began to become more and more delicious due to the high concentration of light, and after a while it was ready to eat.
Instead, reflective glass can also be used at the top, which allows the sun to pass through it.
Different types of solar cookers work differently;
They are therefore divided into different types.
However, one thing is common among all solar cookers;
Solar energy is used to cook food.
The types of solar stoves are: 1)
Solar cookers that use direct enrichment of sun light: In this type of solar cookers, there is a mirror, the sun falls on it, and after reflection, they are concentrated in a small place, there are utensils for food.
The concentrated light carries a lot of energy and can cook food faster. 2)
Light is converted into hot solar cookers: in these solar cookers, the black surface is applied to the inner surface of the solar cooker.
Black is able to absorb the maximum amount of solar energy and turn it into heat to cook food faster. 3)
Solar cookers where heat is captured: in these solar cookers there is a glass on the top that allows sunlight to pass through it and concentrate on the inside of the cooker.
Here, solar energy is absorbed and converted into heat.
This heat is then stuck by the glass inside a plastic bag or container, creating a greenhouse effect.
In countries with huge solar potential, humanitarian organizations are promoting solar cookers extensively.
There are India, China, Pakistan, Brazil and some African countries with abundant solar energy resources.
Solar cookers are not only cheap means of cooking food, but also prevent deforestation and pollution from fossil fuels caused by the use of wood as fuel for cooking food.
