Aniket Sarkar, a 13-year-old inventor, has developed a low-cost prototype that captures water vapour from dry air for agricultural use. Built entirely from everyday materials, the system is designed to help farmers in arid regions where groundwater or rainfall is scarce.
The idea emerged from Aniket's observation that moisture is present in the atmosphere even during dry spells. His prototype was entered into the 3M Young Scientist Challenge, where it won a prize and drew attention as an early-stage environmental engineering solution.
The invention is not yet ready for farm-scale deployment, but it has given Aniket a clear direction for further development. He hopes to improve the design with mentoring from the competition and eventually turn the prototype into a practical tool for regions facing chronic water shortages.
Indian Opinion Analysis
Atmospheric water generation (AWG) has been largely confined to industrial chillers that consume several kilowatt-hours per litre, making it uneconomical for Indian farms where a tubewell can cost Rs 30,000 to sink. The challenge for Aniket’s prototype is scaling from a cupful to the 4,000, 5,000 litres a hectare of maize needs per season. India’s groundwater table is falling 0.5 m a year in 60% of districts, so any AWG design that works below 30% humidity would be an alternative to deeper borewells. The next test is whether his everyday-materials system can hit below Rs 10 per litre, the price Delhi Jal Board pays for piped water.
