Heating the thermal mass (water bottles) to help provide stable nighttime temperatures, and avoid mold formation on the fruit.

  • November 2012: Solar Food Dehydrator - Stan Cajdler of Brisbane, Australia has developed a solar food dehydrator, which significantly reduces the formation of mold spores caused by the nightly cooling of food. Typically, the drying process can last for several days for sucessful solar food drying. In this design several water containers (for thermal mass) are positioned in the lower chamber of the dehydrator. As the collector plate heats up, it heats up the surrounding air, which rises through the drying chamber. During the day, radiant heat from the collection plates also heats the water containers, which slowly release heat overnight. This overnight thermal air movement through the upper chamber dramatically reduces the formation of mold spores. For more information on Stan’s solar cooker designs check out: Sizzling Solar Systems
  • November 2012: - Heather Stevens of Sun Cooking Australia writes that it’s a great time for Australian companies to invest in solar cooking. The Australian Government has three significant grants available for companies looking to develop or promote environmentally friendly products or services. The Clean Technology innovation program uses Australian Carbon Trading funds, which allow the federal Government to offer matching funding for the development of new environmentally friend products. Stevens said that, “the high upfront costs of commercialization can put off inventors but with these grants the burden is shared by the government”. Steven’s SunRocket portable solar kettle, a grant applicant, uses a Vycor vacuum tube boosted by highly reflective panels to heat water and cook food. It holds 500ml (17oz) and weighs 1kg (2.2lbs) when empty. Another funding opportunity for Australian solar cookers is the Export Market Developing Grant (EMDG), which provides matching funding for any export related costs, including inviting potential clients to Australia to showcase a company’s products.
  • November 2012: “Anywhere under the Sun” is a recently released solar cooking eBook featuring recipes from around the world. Heather Stevens, Australian solar enthusiast and editor of the book invited solar chefs from around the world to submit their favorite recipe, photos and comments on solar cooking. The book is a visually stunning and comphrehensive, with recipes from around the world. The book can be downloaded as an eBook for $1.99(AUD) from 100% of the sale price is donated to Solar Cookers International to assist with their work encouraging solar cooking in the developing world.
  • September 20, 2008: Alice Springs, located in central Australia, will host its second annual Solar Oven Bakeoff on September 20, 2008, as part of the Alice Desert Festival at the Olive Pink Botanic Garden. All are welcome to join in the fun and compete for the Green Spoon Trophy. Oven design and use of local bush foods are two of the award categories. Last year’s recipes included an Australian Quandong dish and a cacciatore. Respected food writer and cook Stephanie Alexander is among the judges. Alice Springs has on average 300 sunny days per year, and recently became one of five communities participating in the government’s Solar Cities program. For more information, contact Kat Taylor.

Climate, Culture, and Special Considerations

The average Australian home produces 500 kilograms of greenhouse gases a year through cooking, says the federal environment department. That is less than lighting (750 kilograms), and heating and cooling (1.5 tonnes), but it is still a fair old weight.
