Without spending a penny on the purchase of gas, the housewives of the Comarca Lagunera may prepare their food daily with the help of sunlight. The food made in solar stoves will not only be cheaper but more nutritious by reducing the quantities of oil and water in their preparation. Dr. Martinez reports that since 2006 the club has been promoting the use of solar stoves, which work with a simple technology to prepare daily soup, tamales, meat, beans, cakes and a variety of foods without using fossil fuels, only solar energy.
