It is little known to those of us living in the Western world that cooking is the fourth biggest killer in the world. A third of the world cooks indoors using solid fuels on makeshift stoves that create toxic smoke that’s both detrimental to health and to the environment. Sickened by the findings, Dutch social entrepreneur Judith Joan Walker created a profoundly brilliant multifunctional cookstove that is also an energy source. The stove can burn a variety of fuels without emission and has other superb features like a USB device charger and a small solar panel that can be placed outside. The stove saves money, energy and lives, now that’s what’s cooking.
