Solar-Powered Cooking One little solar cooker aims to take a big bite out of climate change. The Kyoto Box, designed by Norwegian entrepreneur Jon Bøhmer, is intended as an alternative for millions of people who burn wood to cook food and boil water. Using energy from the sun can reduce carbon emissions as well as deforestation in countries such as Kenya, where Bøhmer lives and runs his company, Kyoto Energy.Bøhmer experimented with the concept for a decade, inspired by the simplicity of a solar device invented in 1767 by Swiss physicist Horace-Bénédict de Saussure. The cooker, which consists of two boxes nestled inside each other and topped with Plexiglas to trap the sun’s rays, has evolved from a homemade cardboard contraption to a $6 plastic version that went into mass production this spring.

EPA: Chemicals Found in Wyoming Drinking Water Might Be From Natural Gas Drilling Federal environment officials investigating drinking water contamination near the ranching town of Pavillion, Wyo., have found that at least three water wells contain a chemical used in the natural gas drilling process of hydraulic fracturing. Scientists also found traces of other contaminants, including oil, gas or metals, in 11 of 39 wells tested there since March.The study, which is being conducted under the Environmental Protection Agency’s Superfund program, is the first time the EPA has undertaken its own water analysis in response to complaints of contamination in drilling areas, and it could be pivotal in the national debate over the role of natural gas in America’s energy policy.
