The Power Of A Fan!

The Self-Generator is an amazing ceiling fan concept that can preserve the mechanical energy after the fan has been powered-off. The system uses electromagnetic induction and the remainder mechanical energy is converted into electricity and saved in the capacitor. This reserved energy can be used for next time.

The designers explain, “according to the energy principle, the Kinetic energy of starting a fan from speed 0 to V is equal to the dissipation of slowing down from speed V to 0. As the friction and capacitor limits exist, approximately after 2~3 times the saved energy can start the fan. The usage is the same as ordinary fan; as long as it’s been charged enough it will automatically work.”
