For Ankith Burki, the global water crisis was not an abstract classroom topic but a challenge worth trying to solve. The seventh-grader from BASIS Independent Silicon Valley in San Jose designed an atmospheric water generator that pulls moisture from humid air, then tested whether sound could make it more effective. His results were striking: low-frequency sine waves increased the device’s water collection by 117 percent. The project earned Ankith a place among 30 national finalists in the 2026 Thermo Fisher Scientific Junior Innovators Challenge, the United States’ premier STEM competition for middle-school students, according to the Society for Science. Read on to know more about his project here:
A question shaped by water scarcity
Ankith’s project began with a sobering reality. More than 4 billion people do not have sufficient access to fresh water, and climate change is expected to make water stress more severe in many regions. Atmospheric water generators offer one possible solution because they can extract drinkable water directly from humid air, reducing dependence on conventional water sources.But there is a significant limitation. Many atmospheric water generators do not produce enough water to be practical for communities that need them most. Ankith wanted to find out whether a relatively simple intervention could improve their efficiency. He focused on sound-induced vibrations, which he believed could help water vapour cluster and encourage tiny droplets to combine, allowing more water to be collected.The idea was both scientific and practical. Rather than treating water scarcity as a problem that only governments or major laboratories could tackle, Ankith looked for an experiment he could build, measure and improve. His work combines environmental concern with engineering curiosity, a pairing that helped make his project stand out in a national field of young innovators, as per the report.
Building a water generator from scratch
Before he could test sound, Ankith needed a working atmospheric water generator. He designed and assembled his own prototype using the Peltier effect, a thermoelectric process in which an electric current moves heat from one side of a material to another. This allowed his device to cool the surrounding air enough for moisture to condense into liquid water. The report further suggested that after several rounds of trials, he developed a prototype capable of lowering the temperature around it by 7.5 degrees Celsius. That cooling pushed the air below its dew point, the temperature at which water vapour turns into droplets. Once the droplets formed on the chilled surface, the device could capture and measure the water produced.The process required persistence. Designing a system that reliably produces condensation is not simply a matter of turning on a cooling component. Variables such as room humidity, temperature, airflow and surface conditions can all affect the volume of water collected. Ankith had to create a repeatable setup before he could make a meaningful comparison between silent conditions and sound-assisted ones.
Testing the power of low-frequency sound
Ankith ran his atmospheric water generator through a series of four-hour tests. He performed 5 silent trials to get a baseline, and 10 other trials with low frequency sound from a speaker. He tested 2 types of wave forms, sine waves and triangle waves, to see if different sound patterns changed the amount of water the machine produced.It was a simple, but amazing idea. These vibrations can affect the movement of water droplets and vapor . Ankith thought that maybe these vibrations can cause tiny droplets to coalesce , that is , merge together into larger droplets . Larger droplets would be more likely to clump together and fall into a container , possibly increasing the overall output of the generator .His measurements showed that low-frequency sine waves were the most effective option. Under those conditions, the device collected 117 percent more water than it did during the silent tests. The result suggests that sound could offer a low-cost way to improve the performance of atmospheric water generators, though further research would be needed before the technique could be applied outside a controlled prototype.
A national STEM finalist
Ankith’s project, titled Investigating the Effect of Low-Frequency Sound in Enhancing the Efficiency of Water Generation in Thermoelectric Atmospheric Water Generators, earned him a place in the 2026 Thermo Fisher Scientific Junior Innovators Challenge. The Society for Science selected 30 finalists from a nationwide pool of middle-school researchers, as per the report on their website.The finalists are scheduled to travel to Washington, DC, from October 23 to 28 for Finals Week. In addition to presenting their research projects, students will take part in team challenges designed to assess collaboration, critical thinking and problem-solving. Every finalist receives a $500 award and competes for more than $100,000 in prizes.Reaching this stage is an important recognition for Ankith, particularly because his project takes on an issue with direct relevance to climate resilience and resource access. The Junior Innovators Challenge is not only about producing a clever experiment. It rewards students who can identify meaningful problems, test their ideas carefully and explain how their work could make a difference beyond the lab.
Engineering with a wider purpose
Ankith has said he hopes to become an environmental engineer. His interest in atmospheric water generation speaks to that ambition, combining the mechanics of cooling systems with the human need for clean water. He’s admitted that he hasn’t personally faced a lot of hardship, but feels that this comes with a responsibility to develop solutions for those with fewer resources and opportunities.That perspective gives his project a broader purpose. Atmospheric water generators may be especially valuable in regions where groundwater is scarce, infrastructure is limited, or traditional water supplies are vulnerable to drought. Although such systems still face challenges involving energy use, humidity requirements and scale, improvements in efficiency could make them more useful in the future.Ankith’s prototype is not a finished answer to global water scarcity, but it is a promising demonstration of what happens when young researchers focus on a specific technical obstacle. A 117 percent increase in water collection under test conditions is a meaningful result, and it points to new questions about the role vibration and acoustics could play in water-harvesting technologies.
Science, music and heritage
Away from the lab, Ankith is also a singer who performs Indian Carnatic classical vocal music. He has described the practice as soothing and as a way of connecting with the musical traditions passed down through generations of his ancestors. That connection to heritage sits alongside his interest in engineering, showing how creativity and technical thinking can coexist in the same young innovator.There is an unexpected link between his musical life and his science project. His experiment centres on sound, its frequency and its physical effect on droplets of water. While Carnatic music and low-frequency engineering tests are very different worlds, both require an awareness of sound as something that can be shaped, measured and deeply felt.For now, Ankith’s work offers a hopeful example of curiosity put into action. By building a device, testing it methodically and looking for a practical improvement, the San Jose student has turned a concern about water access into a nationally recognised research project. His next steps may help reveal whether sound-assisted water generation can one day contribute to cleaner, more accessible water supplies.
