Large quantities of products, tools and methods have fallen into disuse and been forgotten. The project will collect things that deserve to be re-used, investigate the benefits and if necessary produce a new product and re-launch it by established producers and retailers. First is the old ”cooking box”. The utility is versatile: great energy saving, keeping the food warm without cost, tastier confit, no burnt food. The box can be used as a dry pantry and rescue of frozen food if the freezer breaks down or the power is out.
