Kitchen machines with an alternative drive concept. R2B2 is the result of a project to reduce private electric waste production. There are three different kitchen appliances, which are powered by rotating a flywheel with muscular strength. Electricity is not necessary anymore. Wide user studies showed, that a kitchen machine, a coffee grinder and a hand blender are the most needed driven appliances. They all can be placed in the container. A lot of other features are possible to power. All products and pieces are designed by including user studies under the topics long life, high functionality, easy cleaning, easy demounting and high quality look.
