Project 3.2 Solar Furnace or Cooker

Build a device that can be used to cook food by concentrating the sun’s rays on a container.

Concave mirrors can focus the sun’s rays on a small area and create very high temperatures as a result. You can make a basic solar furnace by lining a curved container with aluminum foil and placing a smaller contained with food in it at a point where the reflected rays tend to converge.
