With warmer days here I thought many of you might find this useful. Each year Las Vegas has an average of
- 150 Days above 90 degrees
- 97 Days above 100 degrees
- 22 Days above 110 degrees
Let's use our warm days to our advantage! Of course, if you don't want to make your own solar oven you can purchase them from Sun Oven.
The Kyoto Box is a solar cooker constructed from two cardboard boxes, aluminium foil, and an acrylic cover. The oven traps the suns rays, creating enough heat to cook or boil water. It was invented by Jon Bohmer, a Norwegian born inventor based in Kenya.
The Kyoto Box consists of two cardboard boxes. The inner box is painted black, facilitating the absorption of heat from sunlight, and covered with a transparent acrylic lid to trap heat. The box is placed inside a slightly larger cardboard box that has been lined with aluminum foil; the foil focuses the sun's heat on the inner box. Temperatures inside the box can quickly reach 80 degrees Celsius (176 degrees Fahrenheit) on a sunny day. According to the Kyoto Energy website, temperatures can reach a maximum of 165 degrees Celsius. Bohmer claims that the oven is capable of boiling 10 liters of water in two to three hours.
The Good Human shows their homemade solar oven, which is modeled after the Kyoto Box. There is also this short You Tube Video, which shows a solar oven made with a car solar shade.
