The sun heats us by the method of Solar Radiation.
evaporation
ultra violet
Radiant energy -> electrical energy -> thermal energy
You can heat things (for example, use a solar system to heat water, and use it to take a shower - or use a solar cooker to cook food), and you can generate electricity from the Sun's energy.
parabolic cooker.
A parabola solar cooker works the best and fastest
A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.

Functions of a solar heater
Solar is a device which Run from sunlight
The solar cooker has three major functions. The first function is concentrating the light from the sun into one small area. Reflective materials are used to do this, and the result is that the heat is more concentrated in the solar cooker. The second function is turning the sunlight into heat. This is accomplished by using a substance that can absorb the heat from the sun and store it for cooking purposes. The third function is trapping the heat created by the sunlight. Trapping the heat helps to cook food more evenly and means that the solar cooker can be used on both hot and cold days.
A solar cooker. It's a parabolic concave mirror with the food suspended at the focus. The sunlight is concentrated and heats up the food enough to cook it.
because he did not have stoves back then so he made a solar cooker to heat his food up

Depending on the type of solar oven/cooker, it can be chilly outside, but if there is direct sunlight and especially a high UV index, the cooker can get very hot.
