The Wonderbag Is A Slow Cooker That Needs No Electricity Or Fuel

When it comes to off-grid and sustainable solutions, the Wonderbag is an innovation that allows people to cook meals without needing any fuel or electricity. The Wonderbag is amazing in that it is a slow cooker that needs no electricity or fuel and can cut your cooking costs dramatically. With regular use, the Wonderbag can save you up to 30 percent of your energy bill per month. It is a well-insulated, eco-friendly bag that can cook your food slowly through heat retention. All that you do is prepare your stew recipes, soup, rice, or sauce, heat it to its optimum cooking temperature in an oven, on the fire, or a stovetop, then remove it and seal it up in the Wonderbag. Using an ingenious principle known as thermal preservation, the Wonderbag can continue cooking your food for up to twelve hours, so that your food will be ready to eat whenever you are. The Wonderbag will work most efficiently with pot sizes between two and nine quarts, and it’s best if they only have short handles or no handles at all – so they will easily fit inside the bag. Another wonderful use for the Wonderbag is that it can keep your food cold as well.



The portable, energy and cost-efficient Wonderbag is not only an excellent off-grid accessory for individuals and families, but it’s changing the way that people in third-world countries are living. Because it doesn’t require any electricity to use it, this bag cuts down on the amount of energy needed for cooking overall. Initially, you do need to use a stove top or fire to heat the pot and its contents, but this is only for a short period. Once you place the pot into the Wonderbag, the stove top or fire pit is no longer needed and can be saved for later uses. The food will then cook itself in the bag for however long is needed. Once the food is completely cooked, it will stay warm until it is eaten. All of this means that the Wonderbag is saving coal, kerosene, and gas costs, as well as firewood supplies and the time required to collect precious wood. It is estimated that the simple Wonderbag can save up to thirty percent of energy costs that are often connected with cooking. It is slowing down the process of deforestation because families need less wood to cook with.

Invented in 2008 by Sarah Collins, an entrepreneur who is based in South Africa, and Moshy Mathe, a poverty activist, the Wonderbag is dramatically transforming the way that people in developing countries are collecting and burning fuel. It is also helping those living off the grid to live more simply and easily. The Wonderbag is made from a simple blend of polyester and cotton and its magic lies within its inner insulation layer that consists of polystyrene balls that have been recycled. These balls are what holds in the heat and allow the food to cook for hours at a time; they can also keep food chilled which is extremely helpful for hot countries like Africa, reducing spoilage and helping supplies last longer.



Whether you are living off-grid by necessity or by choice, low-energy and low-carbon-impact ways of cooking are invaluable at this time, and the Wonderbag is one of them. Every Wonderbag has the potential to decrease carbon emissions by a half a carbon ton every year. No matter where you are in the world, if you’re using a Wonderbag, you are helping to bring our world back into balance.
