"Study Desk" Produces Electricity

Posted on Sunday, February 16, 2014 by LEAD

LEADer Nihal Revankar of SDMCET, Dharwad, realized that although many students sit down at their desks to study, very few students actually stay concentrated the entire time.  Students take breaks to text, chat with their friends, play games, browse the internet, etc. Nihal thought to himself, "Why can't students be more productive with their time?". And that's literally what he did.  Nihal designed a model for a study desk that can produce electricity.  First, he fixed an old sewing machine to a desk. He then connected a dynamo underneath the table.  When the pedals are pressed, the wheel of the sewing machine rotates the dynamo.  The dynamo and wheel are attached to a 12v battery which stores the energy produced.  When students are taking a study break, they can press the pedals of the study desk and produce about 9 to 10v of energy.  Nihal expects that this desk will help people save around Rs. 150 on their electricity bills every month and will be especially helpful in villages where electricity is scarce. 
Nihal's project was showcased during Yuva Summit 2014.
