Tech hacks by Indian teams to combat global water crisis
Ahmedabad-based incubator International Centre for Entrepreneurship and Technology (iCreate) collaborated with EarthX, a US-based international environmental non-profit organization, to bring its flagship hackathon ‘EarthxHack’ to India.
EarthxHack, a 32-hour hackathon was held concurrently in Dallas, USA and in Ahmedabad, India, on April 27, 2019 until April 28, 2019, at the iCreate campus in Dev Dholera in Ahmedabad. A live streaming of the EarthxHack in Dallas was screened at the iCreate campus for the participants in India, to interact with and witness the talks by global experts and leaders in the US.
Inaugurating the EarthxHack in India, A.R. Khan, General Manager, National Bank for Agriculture & Rural Development (NABARD), said  “At NABARD, we are always looking to collaborate with organisations  and individuals who  are building solutions that address  challenges related to water, agriculture and development.  EarthxHack is a wonderful initiative  to enable  young minds  to  build better water conservation technologies, recharge systems, harnessing of rain water , amongst other solutions , and c entres  like  iCreate  help  channelize the energies of  these  young innovators  to  in the right direction .”
The hackathon saw 14 teams from diverse backgrounds and age groups, such as college students, entrepreneurs, professionals, startups and projects working on environmental innovation and technology. These participants brought in knowledge and competencies in areas such as electronics, IoT, embedded systems, sociology, broad science and technology and environmentalists.
Problem statement and innovations
This year, EarthxHack 2019 focused on creating solutions to address the global water crisis. iCreate posed 2 broad problem statements to conceptualize solutions and prototypes around:
1) production of water from the atmosphere (saline water and wastewater);
2) detection and prevention of loss of water through transmission.
Some of the innovations that emerged from the hackathon included aluminum-based water condensation system, use of solar heat for water generation from humid air, developing drones and internet of things (IoT)-based system to detect breach and leakage in canals, use of Vapour Compression Refrigeration (VCR) system to get water from the atmosphere and detection of water loss in water bodies by infra-red (IR) satellite imaging.
The winning team comprised of Dr. Vanita Prasad, Pranay Shah, Rajneesh Prasad and Nitin Jain for their innovation of an infrared satellite imaging to detect water leakage during transmission. The team won INR 50,000 and a chance of acceleration at Climate Launchpad, the world’s largest green business idea competition.
