1. ZephyrusThe eco-friendly, 2-in-1 cooling device innovated by Class 10 students of Gurugram’s Shiv Nadar school tackles the challenges of a conventional cooler.
When current flows through the device one side gets extremely hot and the other side freezing cold. This temperature difference creates the dual effect of cooling.
The device, they say, uses 300 ml of water a month compared to 3,000 litres required by a traditional cooler. “It surpasses the cooling capabilities of other products by 2-3 degrees.”
2. SunHarvested CoolRoomsChennai-based 19-year-old Mahek Parvez’s innovation is an eco-friendly grid-less cooling methodology capable of prolonging the shelf life of fruits and vegetables by three times.
The apparatus is designed to mimic nature and its convection currents. When air flows through the device, it is dehumidified, thus allowing moisture to evaporate.
This maintains an optimal temperature and humidity within the tube keeping produce fresh.
3. KavachAnoushka Jolly (14) has reached out to over 20,000 schools across India to spread awareness about the effects of bullying and mental health.
She does this through workshops, talks, and scaling her app Kavach, which allows bullying to be monitored on a real-time basis in schools.
“When cases of bullying are reported by students or their parents, the school will be able to view the data on a dashboard,” she explains.
4. The Malnutrition ProjectMohammed Suhail (18) came up with a unique and inexpensive way of detecting malnutrition in children. His inspiration was a bioengineering professor at Stanford Dr Manu Prakash.
When the child’s saliva sample is dropped onto the paper-based tool that costs Rs 2, the colour the paper turns to determines protein and nutrient levels.
“The method costs Rs 2 and takes merely two minutes. It is a breakthrough in terms of cost and results in zero biomedical waste,” adds Suhail.
5. Auto watering deviceTeenagers Pratyush Bansal and Aekas Singh Gulati hated returning from vacations to see their home plants withering away as they hadn’t been watered.
To solve this, they came up with an auto-watering device made from recyclable materials like empty plastic milk bottles, straws, and wooden boxes, costing just Rs 666.
The device has been made from 80% recyclable material and is designed to water plants for as long as two weeks.
