Amid the deadly threat of Carbon Monoxide (CO) poisoning exacerbated by North India's winters, Archit Garg, a Grade 12 student from The International School Bangalore, recognized the need for an affordable CO detection system. Identifying the reliance of approximately 220 million people on traditional coal and coke heating methods, Garg developed an economical CO detector prototype. He presented its potential for mass production to multiple local governments, emphasizing its feasibility for deployment across millions of households. Archit urges homeowners to strategically place detectors and follow preventive measures to safeguard against CO's risks.
