Indian American Teen Finds Affordable Solution to Make Saltwater Drinkable for Millions of People

Water is the foundation of earth and the elixir of life on the planet. Millions of lives are endangered due to lack of clean, safe, drinkable water in developing countries, including India. Freshwater makes up only 2.5% of the total water on earth, and only 1% of freshwater is easily accessible and safe to drink. The rest is undrinkable saltwater. India itself is grappling with water crisis and trying various measures of water conservation to get over it. About 330 million people were affected by water scarcity across India in summer 2016. A new cost-effective method to make saltwater drinkable is a new ray of hope to flip the depressing pictures of water shortage the world over.

All thanks to Chaitanya Karamchedu, an Indian American high school senior from Portland, for giving the world a new lease of life! He brainstormed an idea for his science project at Jesuit High School, Portland and developed an affordable method to turn seawater into drinking water, which piqued the interest of many international tech firms. This Portland Indian teenager’s method of desalination is a pleasant surprise in the face of the futility of years-old experiments in world-class science labs.

Indian American Chaitanya Karamchedu’s method to make saltwater drinkable is being lauded as a scientific breakthrough. When he found that desalination is not available in many inaccessible coastal areas due to high-cost implementation, he made up his mind to develop a cost-effective solution to desalt seawater. He also discovered that seawater is not saturated with salt. It led him to work with an absorbent polymer to filter out pure water from the water bonded with salt, during his experiment in the science lab at Jesuit High School, Portland.

Chaitanya Karamchedu found that only 10% of seawater is saline but the remaining 90% is not bonded to salt particles. Unlike scientists, he tried to figure out a cost-effective desalination method for the 90% instead of the 10%. His method to make seawater drinkable for a larger part of the world is a boon to millions of people without access to clean, safe water, and those grappling with inadequate drinking water.

Desalination, which is currently a most-practiced method to desalt seawater, is not just too expensive but also not supported by environmentalists for its high-level energy consumption. The Portland Indian boy, Chaitanya Karamchedu’s method to make saltwater drinkable is a cost-effective and energy-efficient solution.

The US Agency for International Global Development awarded him $10,000 at Intel’s International Science Fair so that he could continue the experiment and pursue the research for further development of the method. It also earned him the second prize at MIT’s TechCon Conference.
