Wonderbag is a reusable, zero-energy slow cooker that drastically cuts down on the time needed for food to cook on a stove or fire. Once ingredients are brought to a boil using traditional methods, a pot can be placed in a Wonderbag, where it continues to cook for up to 12 hours. Cooking food safely with limited resources is something many poor families in rural areas struggle with every day.
Using stoves or open fires for long periods of time without proper ventilation can cause sickness or even death. Every year, household smoke inhalation from meal preparation contributes to more than 4 million deaths globally.
