Solar Heated Grill

Solar Heated Grill ABSTRACT This select aimed to find out if an old fit out shockand a thick tin foil can be converted to amore useful writing of cooking equipment. The feasibility of reflective solar heated grillthat is built from a unlife similar box, tin foil, andposterboard as an alternative cookingequipmentwas studiedin thisresearch project. The composition board boxwas cut upandshaped. the tin foil is settled in the middle making it looks exchangeable a slide. we go distant inthe heat of the sun. thebarbeque sticks were placed in thespot where reflection of thesunlight focuseson the hotdog . just like areal skewerthe hotdog were cooked therefor minutes. asted it. and voila. real hotdogs on stickjust like mom used to cook. General Objective This study thru physics aims to find out if an old shoe carton box can be useful to makean alternative cooking machine. Materials/Equipment 1. Two pieces of heavy cardboard (like the sideof a cardboard carton). The first piecemust be at least ten inches squareand the second little piece must beat least four inches by five inches. 2. A piece of light posterboard eight inches wideand sixteen inches long. 3. Twelve-inch wide atomic number 13 foil. (You will use close to 32 inches of thematerial. ) 4. Some masking videotape. You may experiment with other types of tape. ) 5. Nine inch long sticks nigh 1/16 inch in diameter. You may also use lengths of heavywire. Procedure Select a long narrow box the longer thebox the more heatcollection is possible. Choose a focal length between 5 and 10and design a parabolic curve as seenin the picture. One template could beused for all the cookers. Trace the curve onthe open end of thebox so that it is centered and straight2. Cut out the curve with a utility knife. Stress the importance of organism exact. Measure and cut a piece of posterboard that will fix flush against the opening tothe box.Attach this with tape beginning at the center and working toward toedges. Cover the curve with white glue and applyaluminum foil shiny side out. Start inthe middle and smooth toward the edges. Try not to wrinkle or fold the foil youwant it as smooth as possible Use two scraps of cardboard taped to each side as supports. Using the sun or aprojector light, test the focal point. at that place should be abright spot where light isconcentrated mark this spot and puncha repair for the skewer. Use a sectionof acoat hanger from which the paint hasbeen removed for a skewer
