InnoWah - PALS4 Innovation Challenge

The ‘Innovation Challenge’ – an initiative of Pan IIT Alumni Leadership Series was organized in the last week of March at IIT Madras Research Park. The theme was the challenge was as Alternative energy and Clean Tech as part of the Swachh Bharath initiative.

Eco-friendly innovations

Students from various engineering colleges displayed as many as 13 projects based on five focus areas namely:

1. Energy, 
2. Solar power, 
3. Public hygiene, 
4. Waste recycling 
5. and Water purification. 

The top 13

Aimed at recognizing promising talent for future entrepreneurship and startups, 13 projects were short-listed from over a 100 submissions. An exhibition of the projects was also held at IIT Madras Research Park.

Among the many interesting entries was Pratyusha Institute of Technology's project featuring a two-level water purifier using banana peel. The first layer of purification was through activated carbon, while the second was through banana peel pellets stuffed in a ceramic candle. Karthik Raj, the student who presented the project said, “bacteria would reduce by around 60%. The cost price is just around Rs. 800, and while in a Reverse Osmosis purifier there is 50% water loss, no water is wasted here.”

The Agro Rover’ built by students from Hindustan University was aimed at easing the process of tapioca farming, by using robotic arms to pluck the root. “The rover can be operated through WiFi or through a wired switch, and can also run on solar energy,” said Muthukumaran, the faculty advisor for the team.

The finalists were mentored for three days by industry veterans from forums like TiE Chennai. They were given orientations on concepts such as marketing, finance, business plans and more.

The winners 

First prize: Solar powered LPG gas leakage detection and control system

KCG college explaining their project

The prize-winning entry by Sunil Kumar, Saravanan R and S Prathap, final year students of electrical and electronic engineering at KCG College of Technology, was an innovative Solar powered LPG gas leakage detection and control system which can ring an alarm to alert gas leakage, send a message to users, prevent leakage due to a valve fixed between the stove and cylinder, and send a message to the fire department in case of excessive leakage. The device also has a mechanism to detect low levels of gas remaining in the cylinder following which a message will be sent to the gas agency.

Second prize: Waste plastic pyrolysis reactor

Hindustan University bagged the second prize for their presentation on ‘Waste Plastic Pyrolysis Reactor' which focussed on water recycling. 

Third prize: Fuelling the future 

Pratyusha Institute explaining their project

An all-girls team from Pratyusha Institute of Technology won the third prize for their presentation of hydrogen as an alternate fuel solution to power auto mobiles. Pradeepa, a member of the team explained that electrolysis was used to separate hydrogen from water. “With a litre of water, we can have a mileage of around 65 km, it is 20% more efficient than petrol,” Their investment for each system was estimated at Rs. 1500, and they plan to market it at Rs. 3000 to meet costs.
