Innumerable designs to instigate solar cooking have been advanced worldwide. Strengths and weaknesses have become apparent when promoted in widespread field applications. The ‘Blazing Tube’, a novel solar cooking appliance, successfully addresses the shortcomings of many other solar cookers. Notably, this novel solar cooking appliance excels in efficiency, durability, reliability, as well as safety and convenience for users. Using the Sun’s Power Among the many human applications for solar energy, cooking with sunlight has long been promoted internationally. Hundreds of solar cooker designs have been crafted and implemented in suitable cultural and environmental contexts. By far, the developing nations have most often sought to bring solar cooking to the masses of people currently reliant upon solid fuels such as wood, dung, and coal.
Various tasks have been assigned to solar cookers, including food preparation, boiling drinking water, desalination and even autoclaving. Many current designs have demonstrated the ability to fulfill such functions, yet the uptake globally has been very limited. Many factors account for this limited success at implementation of solar cooking including efficiency, reliability, durability and costs related to the technologies. Yet advanced materials and new designs, combined with resolve, continue to advance the state of the art.
One such innovation is the Blazing Tube solar appliance. Its improved characteristics are highlighted through comparative testing with a limited number of commercially available solar cookers. The testing was undertaken in Honolulu, Hawai‘i during the month of December. Although the test site had a favorable annual insolation rate of 500 cal/cm, the wet winter weather challenged the performance of all of the test units.
