Picture of Solar Thermal Cooker by Rico, Jose, and Jeremiah
The goal of our project, solar thermal cooker, was to create a cheap device that could convert the light from the sun to as much heat as possible. Specifically we wanted to get our solar thermal cooker so hot that we could boil water, and cook sausages. To achieve this goal we need to get at least 212 degrees Fahrenheit. With that in mind we were able to get our solar thermal cooker to about 170 degrees Fahrenheit in an 75 degree windy weather. The group of people that would most like our project would be destitute people living in very poor areas around the world that cannot afford high tech solar thermal cookers. To be able to build our solar thermal cooker you would need the following:
1.  One saucer or trash can lid.
2. One roll of reflective tape or aluminum foil  (reflective tape would work best)
3. One pair of scissors 
4. One roll of duck tape
5.  2 pieces of wood so that it can act for a frame for the saucer, or cut off the bottom part of the satellite dish. 
6. one hammer
7. one pack of nails
8. sausages 
9. A black pan 
10. water with some kind of bowl
11. glue
Even though it may seem like a lot of materials we spent around 10 American dollars on all of this equipment, especially because you could use aluminum foil. Also, if you are worried that this will take you a long time to assemble, we assembled our project in 3-4 hours. If this seems like a long period of time, we assure you that you shall not be disappointed by the end results. The final dimensions of the project end up being height = 20 inches, width = 31 inches, length = 30 inches. The only materials that would be hard to find would be the reflective tape, but we reiterate that there is no shame in using aluminum foil. Substitute materials are of course the aluminum foil, and if you don't have a hammer you could always use a shoe. In order to not bore you with a ton of pictures we included to of the most essential materials 

Using the lid as a reflective dish is a great idea! Thanks for sharing!
