Parvati Solar Cooker (Twelve Sided)

Construction of Parvati solar cooker (Twelve sided) is given below

This is Modified Dual angled Funnel Cooker made in 12 sections This is similar to D!T"design of Teong # TanThere is one minor difference between design of these two cookers

!$$erture si%e of Teong # Tan&s cooker is ' inches while that of Parvaticooker is 2 inches

and ratio of length of sides "olar ra* reflection of both the cookers is shown in Fig ! and + ,ehave not done com$arative stud* between these two designs so far

Fig ! - D!T" ( Teong # Tan) Fig + - Parvati Cooker

Dimensions of single section are given in Fig1 These dimensions are for cooker having rimdiameter of 2 feet For rim diameter of ' feet and feet multi$l* these dimensions b* 1. and 2

res$ectivel*

Fig1

To sim$lif* the construction we decided to make it out of single sheet of aluminum or cardboardinstead of making multi$le section and /oining them together !$art from sim$lif*ing

construction this strengthened the cooker

Take a rectangular sheet of dimension 20 0 Draw a semicircle of 20 radius Divide thissemicircle into 12 e3ual $arts b* re$licating 12 times the drawing of single section Com$lete

drawing resembles as shown is fig ' The drawn $ortion is cut along the edge 4ou will have thesheet now as shown in fig 2



5e6t *ou have to bend this to form solar cooker First bend the 7!0 $arts of all sections to the

angle of 1'. degrees with $art 7+0 Then bend $art 7+0 of all sections to the angle of 1.degrees with Part 7C0

5ow start bending all 7C0 $arts on the inner side so that each 7C0 $art makes an angle of 1.degrees with ne6t one !fter bending is com$lete /oin together two ends of 7C0 $arts b* using

$a$er stri$ and glue For aluminum sheet use nut bolt and connecting stri$s

!ll 7+0 $arts will form the lower cone while all 0!0 $arts will form the $art of base ! circular

disc of the diameter of 89 has to be fitted to bring together all 7!0 $arts For cardboard $astethe ring Then $aste reflective $a$er or aluminum foil For aluminum cooker aluminum disc has

to be bolted The $hotogra$h of aluminum disc bolted is shown in the $hotogra$h Thiscom$letes the construction of Cooker The inner surface of aluminum cooker will need

$olishing and $rotective coating
