PANJIM: When the going gets tough the tough get innovative. And young engineering students of Don Bosco have shown exactly how at the ongoing science festival in Panjim.

One team of Don Bosco College of Engineering students worked on an Oxygen Concentrator and presented it at Science Festival. The concentrator sucks the air from the atmosphere and delivers it as oxygen to Covid patients.

The team which fabricated the Oxygen Concentrator consists of Sahil Chitrapukar, Shahul Ahmed, Keenan Cardozo, Akshay Bhatule, Nirbhay Borkar, 

and the team mentor was Professor G Samant.

The team exhibited their device, which became a key attraction, at the Science Film Festival of India - 2022.

Keenan Cardozo, group leader, said that the key intention behind designing and fabricating of the oxygen concentrator device was to help solve the issue of oxygen shortage across the globe faced by Covid-19 patients.

Explaining the functioning of the Oxygen Concentrator, students said, “The atmospheric air consists of 78% nitrogen and 21% of oxygen and 1% of argon and other compounds. If a person is suffering from Covid, the person cannot separate these gases. This person needs external aid. The oxygen concentrator which the students have fabricated will do the job.”

“We take the atmospheric air, compress it and we generate pressure and remove the moisture. Then we pass it through a column that contains zeolite. Zeolite is a chemical compound that keeps the nitrogen to itself and lets go of the oxygen. That oxygen is stored in a particular cylinder and is then given to the patient at the other end,” students said.

Before giving it to the patient, since the air is dry the humidifier bottle adds some moisture to it, so that patient does not have to breathe the dry air.

On the other hand, the team of Eldrich Godinho, Valen D’Souza, Riff Fernandes, Alan Fernandes, and Chris Fernandes from the Mechanical Department, purchased parts from the market and executed their own design to fabricate a drone that is useful in agriculture. The main USP of this drone is spraying pesticides on high-risk trees such as coconut trees. “Such drones are not exploited much and hence we thought of renting out such drones to the farmers,” Godinho said.

The fabricated precision spraying drone can scale a height of 10 to 20 meters, does a flight time of 20 minutes, and can carry 5 litres of pesticide. The total project cost is Rs 1,60,000.

The part of the drone includes a 3D printed tank, batteries, a camera, and a carbon-fiber body. The USP of this product is precision spraying. A camera is attached to the drone, which sends real-time pictures to the mobile app. Based on these live images spraying can be done. The most important thing is that the farmer will not waste pesticides and secondly the farmer does not have to take the risk of climbing trees.

The students credited the Principal of Don Bosco Engineering College Dr Nina Panandikar, Director Fr Kinley D’Cruz, HoD Ajit Salunke, mentor Gaurish Samant for the guidance.
