Introduction

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.

Matériaux

Car inner tube

Flat piece of wood

Black pot or pan

A pain of glass

Emergency blanket

Outils

None :)

Étape 1 - Step 1

Take an old car tube. If the tube is punctured get it patched. Inflate the tube and keep it on a wooden board. Wrap the silver emergency blanket around tube.

Étape 2 - Step 2

Get your black pot or pan (if its not black you can make it vlack in a fire). Put all the ingredients for cooking Khichdi - rice, daal, salt, water etc. in the cooking pot.

Étape 3 - Step 3

 Place the cooking vessel inside the tube. Cover the tube with a piece of plain glass. Within three hours the Khichdi will get cooked.

Étape 4 - Step 4

What happens? The place in the center of the tube is like a closed cavity. Air neither goes out or comes in. The rays of the sun enter the glass and get trapped. Slowly, the temperature of the cooking vessel rises and the Khichdi gets cooked.
