Solar cooker

My solar cooker is doing pretty well. Two weeks ago, temperature reaches to 200 degrees. I think we have to increase the surface area of the part that reflects the sun light. Also, I think our solar cooker need a stand kind of thing because when outside is windy, it moves so much so it can't get much sunlight.

I think my solar cooker is pretty good. It reflects the light to the right spot and it works well. Type of my solar cooker is box cooker. The reason why I choose the box cooker is box cooker is much easier to make than the other kinds of cookers. Simple and easy to make is very important because a lot of developing countries don't have nice materials like us. Also, they don't know English so we can't teach them how to make solar cookers. Because of these reasons, we have to make easy and simple, less-material solar cooker.  I saw some pretty interesting solar cookers on internet, and a lot of them has reflective material like mirrors or aluminum foils. I think I have to make my solar cooker with reflective materials. So far, I think my plan is pretty good and I'm keep researching for that.

Solar cooker

So far, I think my solar cooker it pretty good. It reflects the light to the right spot and it works well. Type of my solar cooker is box cooker. The reason why I made my solar cooker to box cooker is it is easier to build. My solar cooker has four wing kinds of thing covered with aluminum foil that reflects the light. Inside of box is all covered with foil. We are using black-painted glass bottle because black observed the heat. This solar cooker is for developing country so it has to be easy to make.
