Innovations with bright expectations spark India International Science Festival


New Delhi: Uzma Bano, a class 8 student from Lucknow, took not more than a month to design and build a solar-powered air conditioner to help relieve long power cuts her school would endure during summer months. That was a reward in itself for this daughter of a cold drink seller. But showcasing it in India International Science Festival (IISF) at IIT-Delhi made her feel proud.

My design will help children in the school as well to save electricity. This is eco-friendly and will not cause global warming, she said.

Her AC consists primarily of a 25-litre ice-box, a portable table fan, and a solar panel and it cost her about Rs 3,500.

Bano’s is just one of the 800 projects made and displayed at IISF by pupils of classes 6 to 10 from across the country, offering energy solutions to the world that is desperate to move away from burning more hydrocarbons.


Participants, representing all states and remotest of places, including the Andaman and Nicobar Islands, had to win district and state-level science competitions to qualify for IISF. Their models had to be built keeping in mind the problem their district or state was facing.

From a garbage management system to a solar-powered hybrid bicycle and a thermoelectric generator, the students brought the best of their ingenuity to bear on the challenges their communities faced.

Oza Alay Kumar’s ‘artificial tree and wind tunnel’ was adjudged the best model. The boy from Gujarat’s Mehsana district got the gold medal for it.

The silver medal was bagged by Ananya Y R of Karnataka’s Chikkmagaluru district for her ‘biodegradable plastic’ model.

Prithvi Raj of Jharkhand’s Garhwa district won the bronze for his jacket that helps the blind.

In addition to top honours, 57 participants were given awards of appreciation. (IANS)

Students of IIT Delhi Launch Reusable Sanitary Pads

“We have provided samples to authorities in African nations who are currently conducting test on them. We hope for a positive result very soon,” Archit added

Students of IIT Delhi on Tuesday launched reusable sanitary pads made with composite banana fibre. The startup claims that these pads can last up to two years.

The reusable pad is developed by Archit Agarwal and Harry Sehrawat based on inputs from several IIT Delhi professors.

“The reusable pads are ultra-thin and are highly absorbent with Quadrant True Lock Technology which makes the pad leak-proof and avoids creating any rashes,” Archit told media while launching the pads.

A patent has also been filed for the design.

These reusable sanitary pads can be used up to 120 times after washing them in cold water with detergent after every use.

A Reusable Sanitary Pad is made up of four layers of different fabrics. A pack of two pads is priced at Rs 199.
