The basic idea of the Warm Wheel is to use a bicycle wheel to transport, heat and pressurize water to have a shower everywhere. This concept could be suitable for people who have to move to great distances to get clean water for hygienically use. At the same time it transport 16 liters of water inside the wheel while a 12V hub dynamo is heating it up. The pedaling motion mechanically produce pressure by a peristaltic pump for a 12 minutes hot shower.. Pedal and shower!
