Why Solar cook?
A specialized Wikipedia web site emphasize that solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen. For millions of people who lack access to safe drinking water and become sick or die each year from preventable water-borne illnesses, solar water pasteurization is a life-saving skill.
According to Turkenburg 2000, in some regions cooking energy requirements place a great pressure on biomass resources while also causing considerable inconvenience and health effects to users in the collection and burning of biomass. Considering that these regions also have significant levels of solar radiation, it would appear that cooking provides a significant and beneficial impact.
Solar cooking devices have certain limitations and can only supplement, not replace conventional fuels. A home that uses a solar cooker regularly can save a third to a half of the conventional fuel that is used for cooking. The economic payback time is usually between 2 to 4 years. The large-scale use of solar cookers, however, will also require some adjustment by users.
In 2002, the workshop Towards Earth Summit came with a proposal named: Global Solar Cooker Programme. In this proposal it is highlighted that solar cookers have the potential to affect up to 800 million tons of CO2 savings annually, at a very favourable price of between 2 Euro and 5 Euro per ton mitigated. Also that, although efforts to introduce solar cookers have been fragmented in the past, they have nevertheless recently overcome most of the technical supply side barriers that have inhibited the wide-scale introduction of this technology, such as poor performance and safety characteristics. Solar cooking is now poised, worldwide, to deliver significant benefits to both the environment and the quality of life for millions for people of all ages.
In her new global survey of solar cooking Dr. Knudson reports that despite an urgent need for the technology and strong demand in many communities where it has been introduced, there is still much work to be done. Specifically, the study finds ongoing promotional efforts in only a small fraction of countries where the technology could offer great social, economic, environmental and health benefits. This suggests a good news/bad news situation: Opportunities to improve lives through the introduction of solar cooking are as extensive as the need is compelling. However, inherent challenges have impeded proliferation of this technology.
