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.
Solar is a device which Run from sunlight
Functions of a solar heater
Materials that are good conductors of heat, such as metal or blackened surfaces, heat up water faster in a solar cooker. These materials absorb and transfer solar energy more efficiently, resulting in quicker heating of the water.
In a solar cooker, solar energy (light and heat) is absorbed by the reflective surface and converted to heat energy. This heat energy is then transferred to the food in the cooker, causing it to cook or heat up.
because he did not have stoves back then so he made a solar cooker to heat his food up
