Water
This work of art can annually desalinate 1.5 billion gallons of drinking water
Global warming is making drinking water scarcer. Desalination can provide a solution in many coastal areas where most of the world population lives. But desalination requires a lot of energy; making fresh drinking water expensive. “The Pipe” is designed to solve that problem. Here it is Read More...
This tiny device makes dirty water drinkable in just 20 minutes
This tiny device makes dirty water drinkable in just 20 minutes Genius. Scientists have developed a tiny device the size of a postage stamp that can kill 99.99 percent of bacteria in water in just 20 minutes.
