On June 22, IIT Kanpur achieved a significant milestone by successfully conducting an experiment on cloud seeding. This project, led and funded by the institute, aims to explore the concept of artificial rain through cloud seeding technology.
Project Initiation and Progress
The idea of cloud seeding was pursued five years ago by IIT Kanpur, and the project was later approved by the Directorate General of Civil Aviation (DGCA). Due to the outbreak of the Covid-19 pandemic, progress faced a temporary halt, but validation from DGCA was obtained in the last six months. The recent flight test marked a crucial step, evaluating firing and aircraft dynamics, with DGCA members present to observe and gather relevant data.
Understanding Cloud Seeding
Cloud seeding involves spraying microparticles of salt, usually AgI, into existing clouds. This leads to condensation, increasing the particles’ weight and resulting in precipitation. Flares containing a salt mixture and gunpowder are utilised to release the mixture into the clouds. IIT Kanpur explored alternative salts, reducing the amount of AgI in the mixture, achieving promising results.
Environmental Impact and Benefits
Cloud seeding can redistribute rainfall in regions experiencing little or no rain, and it can temporarily alleviate pollution in large cities with high pollution levels during winter. The project aims to serve these purposes while considering the potential environmental impact.
Future Prospects
IIT Kanpur’s team is working towards obtaining full approval from DGCA, and various state governments have already shown interest in the project. Once approval is secured, further trials will assess the outcomes. Though artificial rain remains a distant goal, the success of this project is a testament to IIT Kanpur’s dedication and cutting-edge research.
IIT Kanpur’s strides in cloud seeding technology open up new possibilities for mitigating water scarcity and pollution in India. The institute’s relentless efforts and achievements provide hope for a brighter, greener future.
