Energy Harnessing Fan Using Dynamo

A dynamo is a type of electrical generator that uses a commutator to produce a conducting current. By rotating the coil, a dynamo generates electrical energy or a direct current using the principles of electromagnetism. A dynamo generates electricity through rotating coils of wire and magnetic fields. Faraday’s law of induction converts mechanical rotation into a pulsating direct electrical current. a Dynamo with a $2 \times 2$ matrix arrangement. It consists of four dynamos. It is connected to a fan via nylon-based mechanical gears, so that the rotation of the fan can provide mechanical energy, which is then converted into electrical energy. The ultimate goal of the project is to either use the generated energy directly in an electrical device or store it in a storage device. Therefore, a system that can help society use electricity efficiently is the dynamo fan system. The fan can generate electricity and airflow at the same time. Here, nylon gears are used to reduce the friction between fan and dynamo while it rotates. By exploiting this dual purpose, the fan is sustainable and energy efficient and can be used in off-grid situations or as an emergency power source in various contexts.
