One drawback of using solar-powered cookers is that on a cloudy day, you won't be able to get your food.
However, industrial designers Anil Dincer and Murat Ozveri have designed a new solar cooker for DesignQuadro, which can harness sunlight for electricity even on a cloudy day.
The top-mounted solar panels generate enough electricity to cook a meal for two. The cooker comes with a touchscreen interface that allows the user to set the cooking time and can be connected to a proposed website where one can upload the cooking stats besides determining the nutritional value of the meal.
