Parabolic dish solar cookers can cost you anywhere from $250 to $400. So why pay that when you can make one for around $9?
This DIY Parabolic Dish Solar Cooker is simple to build. This video contains complete step by step instructions. This parabolic dish cooks just about as fast as a professionally made one. This would be great for off grid living, camping, or just cooking in your backyard.
The 3 foot dish is made using only cardboard, poster board, foil and glue. (3 large boxes 18″x18″x24″ – 3 pieces of poster board and glue).
The boxes can be found at Home Depot and posterboard is from Walmart. FYI, Walmart sells the same size boxes so everything you need can be found there.
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.
The dish in video has an 18″ focal point and is lined with heavy duty Reynolds wrap aluminum foil, and has about 85% reflectivity vs. 98% reflectivity of a professionally “mirrored” dish.
WARNING: use caution around the dish. gets very hot. Do not leave unattended in the sun.
