Introduction :

Basic objective of this project is two-fold:

learn the use of solar power for cooking purposes, and

 use the property of parabolic mirrors to concentrate the incoming light rays parallel to its axis on its cups.

Concepts :

 radiation at the earth's surface: The solar radiation on the upper atmosphere is  exp14 kw. But only a fraction of it reaches the earth's surface in India, on an average, i.e. average solar radiation intensity is 1.5 kw/cm squared. Out of this only 800W /cm squared is al intensity, and in this case, useful to us.
