Today Germany produces one-third of its energy using Solar and Wind. So, let’s explore the working of a Solar Fan. This is a plastic 4-blade propeller. You affix this fan to the shaft of a toy motor. The two electrical wires coming out from the motor are attached to two screws on a wooden stand. The motor-fan is also clamped to the wooden stand. The fan must rotate freely on its shaft. This is a small solar panel. On the underside are two leads connected to two crocodile clips. Attach them to the screws connected to the motor and place the whole assembly out in the sun. The solar panel will produce a current which will spin the electric motor. On camouflaging the solar panel it will stop producing electricity and the solar fan will stop. This work was supported by IUCAA and Tata Trust. This film was made by Ashok Rupner TATA Trust: Education is one of the key focus areas for Tata Trusts, aiming towards enabling access of quality education to the underprivileged population in India. To facilitate quality in teaching and learning of Science education through workshops, capacity building and resource creation, Tata Trusts have been supporting Muktangan Vigyan Shodhika (MVS), IUCAA’s Children’s Science Centre, since inception.
