Indian-American student devises method to make seawater fit for drinking
Chaitanya Karamchedu, an Indian-American student, has found a way to make seawater safe for drinking.
The technique developed by Karamchedu is simple, low cost and efficient.
Seawater contains salts and is not fit for humans to drink.
Karamchedu wanted to find a way to put an end to the shortage of clean drinking water in the world. His method is based on the removal of salt from ocean water and turning it into fresh water.
This is done by a hydrogel created by Karamchedu to separate freshwater from seawater.
