Introduction

A solar heated grill can be built from a composition board box. Sn foil. and poster board. Sunlight hits the brooding surface and focuses on the hot Canis familiaris held in the centre. Students can work in braces or separately if there are adequate stuffs. This is a parabolic cooker we built a piece ago. so unluckily we can’t show measure by measure exposures of it’s building. However. it’s comparatively easy to see how it was put together. It makes a great Physics undertaking. Unlike most. you’ll really acquire some usage out of it afterwards. Some of the rules it demonstrates are: 1. Opticss: concentrating parallel beams of incident visible radiation through the usage of a parabolic mirror. 2. Energy transmutation: visible radiation to heat

3. Renewable energy: solar power

Aim

General Objective: This survey thru natural philosophies purposes to happen out if an old shoe carton box can be utile to do an alternate cookery machine.

Significance OF THE STUDY

This survey aims to happen out if an old shoe carton box can be utile to do an alternate cookery machine. participant is important to different sectors for assorted grounds: · Serve as an eye-opener for those who don’t have a grill in their backyard who want to change over their old shoe box carton into a hot dog grilling machine. · Provide information to pupils and instructors with regard to the recycling of carton box or old shoe box ·

service as actuating factor for the schools or establishments to direct their pupils and to Further beef up their capablenesss for developing old carton box into a cookery grill and other procedures to maximise the recycling of old carton box. Furthermore. the result of the survey will supply through empirical observation ? based information to policy shapers in Ecological recycled Waste Management. ( RA 9003 ) debris cartons are normally stocked or thrown out elsewhere. Converting these non-functional cartons does non merely back up RA 9003 but it besides opens an avenue to develop engineering in the community.

Methodology

Materials/Equipment:

1. Two pieces of heavy composition board ( like the side of a unlifelike carton ) . The first piece must be at least 10 inches square and the 2nd smaller piece must be at least four inches by five inches. 2. A piece of light posting board eight inches broad and 16 inches long. 3. Twelve-inch broad aluminium foil. ( You will utilize about 32 inches of the material. ) 4. Some cover tape. ( You may experiment with other types of tape. ) 5. Nine inch long sticks about 1/16 inch in diameter. You may besides utilize lengths of heavy wire.

Procedure
1. Choose a long narrow box ; the longer the box the more heat aggregation is possible. Choose a focal length between 5? and 10? and plan a parabolic curve as seen in the image. One templet could be used for all the cookers. Trace the curve on the unfastened terminal of the box so that it is centered and straight.

2. Cut out the curve with a public-service corporation knife. Stress the importance of being exact. Measure and cut a piece of paperboard that will repair flower against the gap to the box. Attach this with tape get downing at the centre and working toward to borders.

3. Cover the curve with white gum and use aluminium foil glistening side out. Start in the center and smooth toward the borders. Try non to purse or turn up the foil ; you want it every bit smooth as possible.

Consequence AND
Discussion

This chapter presents the informations. analysis and reading of findings. It is in this portion whereby the informations have been sorted out. tabulated. subjected to statistical analysis and so the findings were interpreted. after we had produced the hot dog grill out of recycled old carton box. and grilled the hot dog at that place thru spotted sunlight contemplations on the Sn foil. We asked person to rate the gustatory sensation and credence of the nutrient.

Decision

Our hypothesis was right. The hot Canis familiaris grill made of composition board can truly cooked delightful hot dogs which is acceptable in the existent universe. the cooker is inexpensive if buil t. because the stuffs are non expensive. produced hot dog is the same as it is cooked in the grill. We think that if a brooding hot Canis familiaris cooker can be built from a composition board box. Sn foil. and Poster board is executable that hot dog can be cooked at that place merely like mammas used to cook. We think that it is cheaper and economical since we live in a tropical state. we think that this will be acceptable in our clip.

Recommendation

On the footing of the decisions formulated. the undermentioned recommendations are offered for possible farther survey. 1. Information airings to the people on the proper recycling of old and bedraggled Carton boxes and other recycled wastes should be intensified. 2. Peoples should cognize the values of recycling non merely the biodegradable and non-biodegradable wastes but besides for them to make their portion to cut down on waste pollution that affects the environment. 3. carton users should be guided consequently on how to recycle destroyed shoe cartons instead than to debris them elsewhere. because dumping them else where. will finally can do mussy milieus. For them besides to assist cut down the fire which are fatal to human existences.

Solar Cooking Frequently-Asked Questions
What are the basic sorts of solar cookers?

There are three basic sorts:

Box cookers -This type of cooker has been the advantage of slow. even cooking of big measures of nutrient. Variations include slanting the face toward the Sun and the figure of reflectors. You’ll find an article discoursing solar box cooker designs here.

Panel cookers-This recent development was sparked by Roger Bernard in France. In this design. assorted level panels concentrate the sun’s rays onto a pot inside a fictile bag or under a glass bowl. The advantage of this design is that they can be built in an hr or so for following to nil. In Kenya. these are being manufactured for the Kakuma Refugee Camp undertaking.

Parabolic cookers -These are normally concave discs that focus the visible radiation onto the underside of a pot. The advantage is that nutrients cook about every bit fast as on a conventional range. The disadvantage is that they are complicated to do. they must be focused frequently to follow the Sun. and they can do Burnss and oculus hurt if non used right. Some of these concerns have late been reduced by Dr. Dieter Seifert’s design. There is a elaborate papers here demoing a big figure of fluctuations on these subjects. You can besides listen to a good debut to solar cookery here.

Who made the first solar cooker?
The first solar cooker we know of was invented by Horace de Saussure. a Swiss natural is experimenting every bit early as 1767. See this article for more info.

Where are solar ovens being used the most?

Box cookers with one dorsum reflector don’t demand to be turned unless you are cooking beans which take up to 5 hours. Panel cookers need to be turned more frequently than box cookers. since they have side reflectors that can shadow the pot. Parabolic cookers are the most hard to maintain in focal point. These demand to be turned every 10 to 30 proceedingss. depending on the focal length.

Should I take the clip to construct a box cooker out of “real” stuffs like plyboard or glass or is unlifelike good plenty?

Unless you need a cooker that can remain outdoors even in the rain. you’ll make merely ticket with a composition board cooker. Cardboard is much easier to work with and holds heat merely every bit good. Some people we know have used the same composition board box cooker for over 10 old ages.

Would a mirror make a better reflector?

While mirrors are more brooding than simpler stuffs such as aluminium foil. but the added addition is likely non worth the increased cost and breakability involved with utilizing a mirror.

What sort of pots work best?

Ideally. you want to utilize a dark. light-weight. shoal pot that is somewhat larger than the nutrient you will cook in it. Metal pans seem to cook best. Hardware shops in the US normally carry dark. speckled. metal pans called Graniteware. Shiny aluminium pots—so common in developing countries–can be painted black or can be blackened in a fire. Cast Fe pots will work. but excess solar energy is used to heat up the pot every bit good as the nutrient. so they will non work in fringy conditions.

If solar ovens are so good. why isn’t everyone utilizing one?

There are many factors at work here. First and first. the huge bulk of the world’s population does non even know that it is possible to cook with the Sun. When they find out about it there is about cosmopolitan enthusiasm. particularly in parts where the assemblage of cooking fuel and the procedure of cookery over a smoky fire is a great load. There are many factors that need to be in topographic point to do it possible for hapless people to solar cook on an ongoing footing. The most successful undertakings have been 1s where the demand was the greatest. the conditions the most favourable. and where the solar cookery boosters have taken a long-range attack to the passage. An illustration of this is the work by Solar Cookers International in the Kakuma refugee cantonment in Kenya.
