The members of our group are Sean Chandler and Dennis Johnson. This blog is about how we are making our solar oven and the materials we are going to use.
Our Question: How will we keep our insulation fire-proof from the amount of concentrated light and heat trapped in the oven?
Our initial ideas are to have two cardboard boxes and paint the bottom of the bigger box black. Then we would put insulation around a smaller box. This smaller box is used to answer our question and try to keep the insulation away from the danger of flames. The small box will be lined with aluminum foil and will have a big bowl in it. This bowl will also be lined with aluminum foil, so that the power is increased because of a spherical design. There will be a cover on the box, also painted black, to keep heat from escaping from the top. There will be a small hole in the top with a magnifying glass concentrated on the bowl. Therefore, magnification, spherical design, paint absorbants, and insulation will all be used to create a powerful design.
Questions:
What if it is raining the day we are cooking off?
How are we going to keep our insulation fire-proof?
What potential flaws are in our initial design?
