On a cool sunny day in Borrego Springs, California, Eleanor Shimeall walks from her kitchen and goesoutside to a strange-looking piece of equipment. She opens a glass door and puts some bread inside. Thenshe opens another flap of a box made of glass and wood and pulls out a pot of chicken and rice. ‘Ah it’s doingnicely’, she says. Shimeall’s meal looks delicious but the remarkable thing is that she isn’t using wood or fossilfuels such as gas or coal to cook her food. Instead, Shimeall is using the sun to make her meal, and she’sdone it almost every day for more than 20 years. Using her solar cooker, she can cook meat, fish, grains andvegetables – just about anything that you can cook on a normal cooker.This method of cooking is becoming popular among people who are concerned about the environment andglobal warming. However, they aren’t the only people interested in this unusual invention. In developingcountries around the world, solar cookers have the potential to save lives. According to one expert, peoplearound the world may soon not have enough traditional fuels. He explains in his own words, ‘With sunshineyou have an alternative to fire. And that’s important for two and a half billion people to learn about becausethey’re running out of non-renewable fuels.’Eleanor Shimeall and her husband, Dr Bob Metcalf founded a company to promote solar cooking aroundthe world 15 years ago. They came up with the idea for Solar Cookers International (SCI) fortwo reasons: they wanted to help stop the terrible deforestation which is occurring insome countries, and they also wanted to make women’s lives easier. The problem ofdeforestation is often due to the demand for trees and wood to use as fuel. Thewomen who collect the wood often have to walk two to three miles. It’s alsotheir job to look after the fire and the smoke can burn their eyes and choketheir lungs. According to the World Health Organisation this problem canbe linked to the death of two million women and children each year.SCI has already trained more than 22,000 families to cook theirtraditional food with a solar cooker. When the women first receive theirsolar cooker it looks like pieces of cardboard and shiny metal. Someonefrom the organisation comes along to show them how to use it and thewomen are always surprised that it cooks a wide range of dishes suchas soups, rice, potatoes, and bread. As well as being a safe way tocook without traditional fuels, SCI say it can make water safeto drink by heating it to the correct temperature. Even moreimportantly each cooker only costs about five dollarsSCI has been making the lives of African women easierwith their solar cookers and now similar projects are alsostarting in countries such as Nepal and Nicaragua.Their goal is to increase the use of solar cookerseverywhere. Dr Metcalf adds, ‘Science is supposedto help and benefit all of mankind and we’ve gotsomething that is good science that could helphalf a billion people in the world.’ With the needfor renewable fuels at a global level, perhaps solarcookers could also have a place in richer countriesas well as the developing world.Proszę o napisanie streszczenia tego tekstu!
