Can nanotechnology make saltwater drinkable?
We spoke with Kamalesh Sirkar at the New Jersey Institute of Technology. He's using a new technology - nanotechnology - to purify saltwater. The most commonly used desalination techniques are called "distillation" and "reverse osmosis." The nanotech technique is also expensive, Sirkar said, but it should work faster than other techniques.
