My Do-it-yourself Parabolic Dish Solar Cooker crafted from scratch. Do-it-yourself solar cooker concentrator. basic to establish. entire instructions. why fork out $250 to $four hundred for one. this dish price $9. cooks just about as rapidly as a skillfully built one. 3 foot dish is built making use of only cardboard, posterboard, foil and glue. (3 large bins eighteen”x18″x24″ – 3 parts of posterboard and glue). bins are from home depot and posterboard is from walmart. for reference, walmart sells the same measurement bins so everything you need to have can be uncovered their. couple of guidelines: make the focal level everywhere from eighteen” to 36″ out from the surface area of the dish and use large obligation foil if attainable. (dish in video has an eighteen” focal level and is lined with large obligation reynolds wrap aluminum foil). has about 85% reflectivity vs. ninety eight% reflectivity of a skillfully “mirrorized” dish. be aware: use warning close to dish. gets incredibly hot. do not depart unattended in the solar.
