Achieving breakthroughs in fusion energy is a key strategy for India to secure its long-term energy needs and transition away from fossil fuels.

Fusion produces significantly less radioactive waste, and the waste it does produce has a much shorter half-life. It also does not produce greenhouse gases.

The Tokamak is a toroidal (doughnut-shaped) magnetic confinement device commonly used in fusion research to contain the superheated plasma.

The reactor successfully maintained extremely high plasma temperatures for a significant duration, a crucial step towards controlled fusion.

Nuclear fusion involves the merging of light atomic nuclei (like hydrogen isotopes) to form heavier nuclei, releasing a vast amount of energy in the process.

Air pollution is a significant global health crisis, and advanced monitoring and prediction systems are vital tools for its management.

The AI-driven insights allow for proactive and precise interventions, moving beyond reactive measures to control pollution effectively.

By providing real-time and predictive air quality data, citizens can make informed decisions to protect their health from pollution.

While social media can provide qualitative insights, direct quantitative data like satellite imagery, sensor readings, and traffic patterns are crucial for accurate AI modeling of air quality.

Project Vayu utilizes AI for data analysis and prediction, and a network of IoT sensors for real-time data collection.
