GoSun Stove

GoSun Sport is a high efficiency portable solar cooker created and sold via US based GoSun Stove. The GoSun Solar Cookers are innovative new solar cooking devices that are considerably faster, more versatile and lighter weight than most other existing solar cooking solutions. It was designed for developed markets, with a higher capacity and lower cost version currently under development for developing markets. Fast to cook, safe and versatile in culinary styles, this technology has a number of distinct advantages that make it a potentially disruptive innovation with the power to change the lives of millions still cooking with time consuming, dangerous, expensive and dirty fuels. Key to realizing the GoSun Solar Stove's advantages over traditional solar cookers is the use of a borosilicate glass vacuum tube as a cooking chamber. These vacuum tubes commonly used as solar water heaters on the roofs of building in the developing world, act as a large greenhouse vacuum flask, efficiently turning sunlight into usable heat and retaining it. When the cooking tray is filled with food is inserted in the tube, the heat is trapped, quickly cooking at temperatures in the range of 400 degrees Fahrenheit. The unit’s glass tube is made of laboratory grade borosilicate glass, popularized under the Pyrex brand name. These tubes are relatively durable and can be easily replaced if broken in both models.

Advantages Include:

  • Speed: The vacuum tube cooking chamber holds heat extremely well, greatly reducing the cooking time required by most solar other solar cookers. It can steam vegetables in 20 minutes or rice in 50 minutes in full sun. An empty tube will achieve an internal temperature of 290°C in just 15 minutes in full sun.
  • Cooks With Inconsistent Sunlight: The insulated nature of the tube gives the GoSun the ability to continue cooking even when clouds pass over the sun, trapping and utilizing the heat previously gathered. This makes the cooker more versatile, allowing for solar cooking in less than ideal conditions.
  • Keeps Food Warm: When left inside the tube, food can be kept warm hours after cooking allowing families to enjoy food cooked by the sun at night.
  • Safe: ­ The properties of insulation that keep the inside of the tube warm also keep the outside cool to the touch, posing no risk of burn or fire. The concentrated light of the reflectors pose no risk of burning eyes or skin like many other styles of solar cookers. It also poses no risk of starting fire, a common and devastating problem when cooking with wood and charcoal.
  • Versatile In Cooking Style:­ The design allows users to fry or bake in the cooking tray or rotate the tube vertically to heat liquids.
  • Low Maintenance: Its uniquely shaped reflectors focus light onto the cooking tube regardless of the sun’s direction reducing time spent readjusting an often time consuming activity with parabolic dish style solar cookers.
  • No Reoccurring Fuel Costs: After the initial investment in the solar cooker there are no additional costs for operation.
  • No Particle Emissions: Without combustion there are no risks related to exposure to airborne particulate matter.
  • Lightweight and Compact: ­ The device weighing approximately 2kg and folding into a hand held package GoSunSport is easily transported for recreation.
