to build themselves, and are generally less expensive to buy than other styles. Variations of these designs have been used to introduce solar cooking in deforested developing countries since the 1950s. High-quality manufactured models of all styles are available for purchase from vendors in a number of countries. Parabolic solar cookers also have a long history of use, primarily in europe and asia. They cook at higher temperatures and usually require more complicated fabrication.

Open umbrella. Using the craft paper make a template of one of the triangular sections of the inside of the umbrella. Using the template you made, trace enough sections onto the mylar to cover the inside of your umbrella. Cut out the sections. Working outdoors or in a very well ventilated area, affix one section at a time to the inside of the umbrella with the spray glue (spraying the umbrella and then placing the mylar pieces). Press out as many bubbles and creases as possible. A rubber roller or a plastic card (credit card, driver’s license, etc. ) can be helpful.

Getting replacement parts – as with the other gosun ovens, getting replacement parts, particularly if you break the vacuum tube, can prove difficult. While it might not be quite as portable as the sunflair mini, the gosun go is certainly a compact, durable, portable solar oven that uses vacuum tube technology to reach surprisingly high temperatures.
