Innovations by school scientists - 2014

While the winners of the Dr. A P J Abdul Kalam IGNITE Awards 2015 are going to be announced on 15th October 2015, we bring to you some of the students who won this award in 2014 with their innovations. These innovations are proof that knowledge has no boundaries or can be confined to any geography or class of people.

Bio-fertiliser from cockroaches
by Ananya Jain, Chandigarh, Punjab

In this experimental setup, better growth of potted plants was observed where cockroach excreta was used as fertiliser. This idea struck Ananya when one day her friends were complaining about the cockroach problem in their homes. She then wondered whether  this pest could be used for productive purposes and then carried out this experiment.

Hygienic cloth hanger
by K.B.S Sukesh, Nellore, Andhra Pradesh

The idea is to have a cloth hanger, which would release UV or any other germicidal rays that will kill bacteria keeping our clothes always fresh & germ free. He thought of this idea after visiting a hospital and realised the need to have germ free clothes to prevent the spread of infection.

Foot operated manual page turning machine
by Swapnanil Talukdar, Guwahati, Assam

This is a lower limb operated manual device to assist upper limb impaired or those which an injury to turn/flip the pages of books easily. This idea originated out of his own laziness. Once after his tuition class, Swapnanil felt too tired to even turn pages of his text book. He then thought of this idea and later realised that it could be used by many other physically disadvantaged persons as well.

Movable seat for physically disabled in cars
by Khushkumar Patel, Ahmedabad, Gujarat

The idea is to have movable seats in four-wheelers so that they can be rotated on their axis and pulled outside. Person can then sit on it easily, push the seat inside and rotate back to the normal position. Such a seat may be useful for a physically disabled person or an obese person.

Advance wind turbine
by Vidit Laad, Indore, Madhya Pradesh

It is a omni-directional windmill, which has a wind concentrator to increase wind speed. It is claimed to work at low cut-in speed as well. He came up with the idea of this windmill while reading his physics text book. He has a habit of doing experiments and trying out things practically.

Improved batteries with fast charging
by Yash Vardhan Goenka, Kolkata, West Bengal

The project involves developing batteries, which can be easily charged at a much faster rate than the conventional ones by using super capacitors having fast charge/ discharge rate and high charge density. The idea came to Yash’s mind while staying at his grandparents’ place where electricity would come for an hour or so; not even sufficient time for an inverter to get charged.

Advance helmet for mine workers
by Preyansh Kotecha and Karan Khatri, Vadodara, Gujarat

The idea is to have a helmet for mine workers, using which their location inside the mine can be identified. The same can also be used for communication purpose if required. Frequent news about accidents in mines and loss of the lives of the miners prompted the two friends to think about the problem and come up with this helmet.

Provision of fourth blue light to reduce traffic jams
by Adarsh Barnwal, Katihar, Bihar

The idea is to have a fourth (blue) light at traffic signal to indicate that traffic jam ahead. This would help vehicles to divert at the signal before they hit the jam thereby easing the congestion ahead. The idea struck Adarsh once when he got stuck in a big traffic jam while returning from his school.

Wrapper picker
by Diptanshu Malviya and Mukul Malviya, Sirohi, Rajasthan

This is a motorized device, which picks up littered pieces of wrappers, papers, pouches, etc and collects them in a storage bin. The brothers thought about this device when they saw a sweeper picking up waste pouches/ paper littered across a bus station. They realised how difficult it must be for him to bend every time to pick up such pieces.

All in one stapler for all size of pins
by G. Vasanth and D. Keerthivasan, Thiruvarur, Tamil Nadu

Their idea is to have a stapler, which can accommodate pins of different sizes and hence eliminate the need to have different staplers.
