A crash course in changing the world.
Oven or stove are too expensive for poor people. Once it's broke, it's hard to repair it and guarantee it will safe like before. The energy that we need to cook on it also not free, sometimes we need to cut down trees and buy gas that if you drop it, it will explode. Therefore, fuel will run out if we don't use it properly and deforestation will extinct trees that aged more than hundred years. I'm thinking that we can change those problems. Solar cooker can help those poor people. The energy that solar cooker using is free. Which is why, I'm thinking that it's good idea if I can create solar cooker to cook my food. If my solar cooker is working, in the future, I can help poor people to create it because the materials that I'm using are cheap and the energy that it will used is sunlight.
