GoSun Stove is a portable, tube-shaped solar oven that’s billed as being powerful enough to cook a full meal, even on cloudy days. Much like the Solar Kettle, this solar cooker uses parabolic mirrors to concentrate sunlight onto a glass cylinder and cook the contents inside. But while the Solar Kettle was built for heating up beverages and boiled eggs, the GoSun Stove sports a slightly larger set of mirrors and a stainless steel tray for food, allowing it to act as a portable convection oven for baking, frying, boiling, and more.
Cook a meal for up to eight people without using a bit of fuel with the Gosun Grill. Its mirrored aluminum reflectors aim sunlight at your food, which cooks safely inside a borosilicate glass vacuum tube. You can cook bake, broil, and fry anything from meats and veggies to soups and bread, thanks to included steam and drip trays.
Simple to use, cool to touch and large enough to feed eight, the Grill was designed with the family in mind.
NO FUEL + NO MESS
Just open and relax. No empty tanks to replace or burnt carbon crud to scrape.
Aside from its tubular design, what really sets the GoSun Stove apart from most solar cookers is its portability. Both the metal stands and parabolic mirrors fold together around the glass tube to form a compact bundle just 8 in (20 cm) tall and 5 in (13 cm) wide. Without any food inside, the whole oven only weighs 3.5 lbs (1.5 kg) and can easily slip into a backpack or be carried using the stands as a handle. According to the developers, it also remains cool enough on the outside while cooking for anyone to pack it up at a moment’s notice without getting burned.
The rest of the unit is made from stainless steel, so while it’s reasonably rugged, at 30 lbs, you can also move it to wherever it’s the sunniest without much hassle.
Once it’s been unfolded and aligned with the sun, the mirrors are designed to concentrate light on the center tube for hours as the sun moves across the sky. After taking about 10 minutes to pre-heat, the stove’s cooking time depends on the type of food being prepared and the intensity of the sunlight at the moment. On a clear, sunny day, it’s said to be capable of cooking six hot dogs in about ten minutes and it’s still effective in cloudy conditions, taking about two hours to bake a tray of muffins. The developers claim to have recorded temperatures as high as 700°F (371°C) inside the oven, but they say it tends to cook best between 200°F (93°C) and 550°F (288°C). The stove also includes a sliding tray with a heat-resistant handle, allowing cooks to add or remove food at any time.
