Good insulation is the most critical requirement for a great performing solar oven. The Sport insulation has an excellent R 6.5 value. It is reinforced with glass fibers to protect it from heat degradation and help it resist crushing.
The Sport insulation material will not absorb water. It is composed of thousands of tiny, sealed, air holes that water cannot penetrate. This is a key design feature because moisture is always present in solar cooking as steam and humidity.
Exclusive Insulated Top
All solar ovens must let in sunlight. Most designs lack insulation in the lid resulting in heat loss during extended cooking times. The Sport lid is insulated with an innovative, exclusive, 1-inch air gap between the thicker molded lid and the taped on plastic film.
Tip-over from wind, rough terrain or slope can be a major issue in solar cooking. The broad footprint and low center of gravity of the Sport make it aerodynamically and physically stable.
Summer & Winter Cooking Positions
The Sport is designed to cook in two positions: a 60-degree slant for a lower angle sun, (winter) and a 30-degree slant for direct, overhead sun, (summer).
The 60-degree slant happens when the oven is placed on its back, and requires slightly smaller pots than come with the kit.
News and recent developments
- March 2006: Last year, 300 unassembled SPORT solar ovens were purchased by St. Edwards Catholic Church of Bloomington, Minnesota (USA) for the community of Jinotega. The cookers were assembled locally under the direction of volunteers Sue Kellet and Andrew Knutson, who were also responsible for trainings. SPORTs were sold to families at a subsidized price of $10. Staples like rice, beans and bananas were popular solar dishes. Other solar foods included chicken dishes, vegetable stews with milk, and cooked mangos. One solar cook commented that the mangos cooked better in the solar cooker than over a fire. More information...
