Self Power incorporates two technologies for public facilities. Theywork together to ensure optimum power- and water-saving performance.Thefirst is an automatic micro-sensor – one of the world’s smallest –positioned at the tip of the spout. Accurate hand detection means onlythe minimum necessary amount of water is used. Located inside the unitis the second technology, a generator that harnesses the energy fromwater flowing through the tap to make the micro-sensorenergy-self-sufficient.
