Can sound help a machine collect more water from air? Ankith Burki, a seventh grader at BASIS Independent Silicon Valley in San Jose, tested that idea with a small thermoelectric atmospheric water generator. The Society for Science reports that his prototype collected 117 percent more water during low-frequency sine-wave trials than during silent trials. That is a result from his described student experiment—not proof that sound can improve commercial water generators or provide a practical drinking-water supply.
What Ankith Burki built and tested
Burki’s project, titled “Investigating the Effect of Low-Frequency Sound in Enhancing the Efficiency of Water Generation in Thermoelectric Atmospheric Water Generators,” used the Peltier effect. In a thermoelectric material, an electric current moves heat from one side to the other, cooling one surface. When that surface cools air below its dew point, water vapor can condense into droplets for collection.

The Society for Science says Burki’s prototype lowered temperature by 7.5°C. He compared water collected in silent conditions with water collected while a speaker played low-frequency sound in sine and triangle waveforms.

- Five silent trials, each lasting four hours.
- Ten additional four-hour trials with low-frequency sound, using sine and triangle waveforms.
- Water collected was measured under each condition.
The Society’s profile reports 117 percent more collected water in the low-frequency sine-wave condition. The available description does not give the exact sound frequencies or amplitudes, ambient humidity and temperature, airflow, energy consumption, water-quality results, or the underlying measurements. Those details matter when assessing whether the finding can be repeated or applied to other machines and environments.

What the 117 percent result does—and does not—show
The result is a promising observation from one student prototype and its reported trials. It does not establish that sound will produce the same increase in another device, climate, or test setup. Nor does it show that the collected water was safe to drink, that the prototype could provide a dependable supply, or that the approach would work at commercial scale.
To evaluate those possibilities, a replication would need to report and control conditions such as humidity, ambient temperature, airflow, electrical power, sound frequency and amplitude, and the method used to measure collected water. The Society’s project summary does not provide those figures, so the reported percentage should be read as specific to Burki’s described experiment.

The Society for Science named Burki one of 30 finalists in the 2026 Thermo Fisher Scientific Junior Innovators Challenge. The Society’s September 16 announcement scheduled the finalists’ event in Washington, D.C., for October 23–28, 2026; those dates are future plans as of October 7, 2026, not completed event results. The finalist page says each finalist receives $500, while the announcement describes more than $100,000 in prizes overall.

The Society’s profile also notes Burki’s Indian Carnatic classical vocal music and his interest in becoming an environmental engineer. That biographical context does not establish that musical training caused or shaped the experimental finding.
