The R2B2 Human Powered Kitchen Appliance Concept


The R2B2 is a wonderful green kitchen appliance concept designed by Christoph Thetard and showcased at the recent Milan Furniture Fair. It uses a sustainable human powered flywheel to drive the spinning blade that allows you to blend, process and grind your food. Very Flintstone-ish, and eco-friendly!

According to Christoph:

Each year the amount of electronic junk is enlarged by additional 50 million tons worldwide. Most of the electronic devices can be found in everyone‘s household especially in kitchens. The latter consists of dozen kitchenware ranging from the old-school mixer to juicer or coffee grinder that all soon or later will increase the amount of waste.
Considering this negative trend, in 2010 Christoph Thetard developed a piece of kitchen equipment that allows you to counteract this development: R2B2. It combines three kitchen appliances with a central driving unit. The heart of the unit is a manually empowered flywheel which works as an energy storage and powers the appliances mechanically and directly.
After extensive studies, a kitchen machine, a coffee grinder and a hand blender were chosen to stand representatively for a lot of other possible appliances. Everything is built up on easy to separate and long life materials. The design is timeless and the technique is very basic and easy to understand. Chopping herbs, grinding cheese or mixing cocktails – all tasks are accomplished with a few pedal kicks only and nearly silent.



It also looks like Christoph is going to put his project on Kickstarter. So we would like to wish him the best of luck in getting this project realized!

    Very nice idea, indeed.
    It would be though important to take into account the resources used to produce such a device. For example the environmental cost of metal mining and processing is often underestimated, and this appliance seems to use a bit of metal!
    I would definitely see such an approach combined with a sharing concept, say more families in a block share the appliance as it sometimes happens with washing machines.
    I would also see a sustainable balance if the appliance passed on to several generations within a family.
    Ultimately we could make current kitchen equipment more sustainable requiring that these are designed and produced to last and to be repair-friendly. 20 years guarantee for all blenders now! 😉
