Cook a meal in 20 minutes with temperatures reaching up to 550°F / 290°C, and finish a meal under cloudy skies. GoSun's Sport Solar Oven is the next evolution in fuel-free cooking. The Sport’s compound parabolic reflectors and tubular design converts nearly 80% of all sunlight entering its refectories into useable heat. The standard package includes a durable borosilicate, evacuated glass tube cooking chamber, two foldable aluminum parabolic reflectors that fold to protect the tube like a clamshell, a stainless steel cooking tray, a rugged scrubby cleaning tool that attaches onto the tray's end and stainless steel carrying handles. A miracle of science, the evacuated glass tube of the GoSun Cooking Technology is a near perfect insulator, allowing one to solar cook in even the most challenging conditions. By effectively capturing light from a broad range of angles, the GoSun does not require frequent readjustment, making it the lowest maintenance fuel free cooking device yet.
