Cyclus has been designed as a hand-held, portable power generator which utilises practical and reliable technologies, combining epicyclical gears, an induction motor and a spring system. Cyclus is small enough to be taken anywhere and used in daily life. Users rotate the lower part of the Cyclus several times, and then the fully wound spring releases, providing constant rotational energy for up to 20 minutes. This energy can be used to recharge various types of hand-held digital gadgets without a negative impact on the environment. Cyclus has been designed as a tactile product, which can be used in daily life. Throughout the narrative of the user-experience, this device serves as a stimulus to promote user awareness of the movement towards a true sustainable society.
