IIT student develops machine to extract water from canteen daal to tide over water shortage in hostel, gets invite from NASA

Water shortage in college hostels could just be a thing of the past thanks to the invention of a third year Mechanical Engineering student of IIT Delhi.


Sagar Sharma, the aforementioned student, claims to have contructed device that will extract water from heavily diluted canteen daal to tide over the usual water shortage at hostels.

Speaking to Faking News on how he go the idea Sagar said, “Water shortage is common here and in the summer season it gets compounded. But I observed that no matter how bad the water situation is in the college, the canteen daal always had truckloads of water. That’s when I decided to put my mechanical engineering knowledge to some good use and work on a device that will extract all the extra water in the daal. This water can then be used in the hostels, where it is much needed.”

A prototype of the device is already being tested and around 200 litres of water is said to have been drawn from the daal served to IIT Delhi students for lunch.

Sagar’s invention has not only got the attention of the water conservationists, American Space administration agency NASA too has extended an invite to the IITian and plans to use the device for future space missions. “Our manned space missions usually have to deal with little or no water. But with this device if we can extract water and then reuse it, that would solve much of our space related problems. Our astronauts can then focus on taking beautiful well lit images of earth at night and then share it on twitter,” said a senior NASA official.

Govt officials too were optimistic that if such experiments were done across all colleges in the country, there would be enough water for everyone. “All college canteens across the country will have these devices and they will be connected via pipes to a reservoir. The water will then be transported to different corners of the country. In the next phase we might even construct a dam across the reservoir and generate electricity,” said a senior Govt official.
