Sun powered stoves have been created by students of SMAN1 Salatiga in order to decrease the use of fuel. It looks easy to make it. The materials are an umbrella, a four square wooden frame and aluminum.
First, replace the cloth of the umbrella with silver aluminum. Break its shaft then put the canopy up-side down. Put a four square wooden frame on the umbrella. It acts as a stove on which a frying pan is put. For demonstration, put a little amount of frying oil and an egg on the frying pan, put a lid which is made of glass on the frying pan. It only takes a short time to make the egg well-done. Let you try and enjoy it!
