German designer Christoph Thetard has created, during his studies at the Bauhaus University Weimar, an electricity free kitchen machine. He called it R2B2. The R2B2 came to life as a result of an eco-friendly project. There are three different kitchen appliances in the R2B2: Coffee grinder, hand blender, & food processor. All are powered by rotating a flywheel with muscular strength. Electricity is not necessary anymore.
The pedal powers the machine up to 400 rpm which produces 350 W energy per 1 minute. The machine even has a storage cabinet for the different items. You can now exercise while cooking and not just that! You are going to cut down on the electricity bill and make a step in saving the environment.
