This solar cooker has been designed by Suresh Vaidyarajan - an architect, who has found a simple solution for a tough problem. This design can be made from items that people no longer need (rubbish) making it potentially free. There are no tools needed to create this cooker. It will be cooking for you in no time!
There is a tremendous shortage of wood, kerosene and fuel for cooking in many place in the world. This design uses the sun- a free, re newable source of energy.
