My Homemade Parabolic Dish Solar Cooker built from scratch. DIY solar cooker concentrator. simple to build. full instructions. why pay $250 to $400 for one. this dish cost $9. cooks almost as fast as a professionally made one. 3 foot dish is made using only cardboard, posterboard, foil and glue. (3 large boxes 18"x18"x24" - 3 pieces of posterboard and glue). boxes are from home depot and posterboard is from walmart. for reference, walmart sells the same size boxes so everything you need can be found their. couple of tips: make the focal point anywhere from 18" to 36" out from the surface of the dish and use heavy duty foil if possible. (dish in video has an 18" focal point and is lined with heavy duty reynolds wrap aluminum foil). has about 85% reflectivity vs. 98% reflectivity of a professionally "mirrorized" dish. note: use caution around dish. gets very hot. do not leave unattended in the sun.
