A 28-year-old MIT graduate has created a leak-detecting robot that could eliminate some of the 2 trillion gallons of wasted drinking water annually

When You Wu was growing up in China, officials would shut off water to his community for half a day each week in the name of conservation. The experience contributed to Wu's interest in the scarcity of water, which he chose to study more in-depth after moving to the United States 10 years ago. The Massachusetts Institute of Technology graduate, now 28, has developed a robot that can find leaks in water pipes. As the robot moves with the water through a pipe, its "hands" touch the pipe and feel the suction forces caused by leaks, Wu told Business Insider.
