With a few common household materials along with time and creativity, one is able to create a personal stove capable of reaching temperatures approximately between 250° to 375° Fahrenheit, solely powered by the sun. Step-by-step instructions are provided by Instructables user sclausson; this invention is known as the Purple Fig Solar Cooker, which can be built with simple items that can be found in convenience areas. The list of materials include a posterboard, aluminium foil, glue, a shoelace, a couple of binder clips as well as purple paint (obviously). According to the creator of this invention, the total cost of the materials should be under $5 (and possibly free to those households that may already have the needed materials).
The posterboard helps form the structure needed for the cooker while the foil is to provide the surface for concentrating the sun's rays. The glue helps to hold the foil to the posterboard while the binder clips aid in holding the structure in place. The shoelace is needed as a key component of the solar cooker but if you are interested in making one, do find out more here at Purple Fig Solar Cooker at Instructables. Enjoy!
