because the fuel they are using to make fires to cook food is causing indoor pollution
The intensity of heat (fire) needed for frying or making chapatis is not available in solar cookers.
Reflectors and mirrors are used in solar cookers to concentrate sunlight onto the cooking vessel, increasing the amount of solar energy captured and improving the cooking efficiency. This helps to cook food faster and at higher temperatures, making the solar cooker more effective.
Solar energy should be captured and stored. This energy can be used for generating electricity with the help of solar panels,solar cells etc. It is also used in solar cookers and solar heaters etc.
it's pretty safe to cook in a solar oven, but it can catch on fire just like any other oven
Solar cookers typically use flat or parabolic mirrors to concentrate sunlight onto a cooking area. Flat mirrors reflect and direct sunlight onto a cooking surface, while parabolic mirrors focus sunlight onto a single point to generate high temperatures for cooking. Both types of mirrors are commonly used in various designs of solar cookers.

Fresnel lenses were originally designed to be used in Lighthouses. Since then, these lenses have been used in car headlights, on televisions, in solar cookers and other things.
A concave mirror is commonly used in solar energy systems to concentrate sunlight onto a smaller surface area, such as in solar cookers or solar power plants. It is also used in reflecting telescopes to collect and focus light for astronomical observations.
Solar energy is being used the most in countries with high levels of sunlight and a commitment to renewable energy, such as China, the United States, India, and countries in Europe. These regions have large-scale solar energy installations on rooftops, in solar parks, and integrated into their energy grids.

a plane mirror is used in solar cookers so that the heat reflected by the mirror to the cooker should be same as the light(heat) given out by sun. hope dat helped
While all Crock-Pots are electric cookers not all electric cookers are Crock-Pots. Crock Pot is a US trademark name that is sometimes used generically to refer to all electric cookers.
