          Sixteen dollars!That's the price of a movie ticket plus tax in Los Angeles. Thanks to an Indian chemist,that amount of cash could also provide clean water for a year for a poor family in the developing world.

          Thalappil Pradeep,a chemistry professor at the Indian Institute of Technology,spent 14 years developing a water filter(濾水器) system that can. remove pollutants from India's groundwater as it is being pumped. The water purifier,which Pradeep first showed to the public in 2012,is the first filter of its kind in India. The country's federal government recently decided to place the pumps across the nation,Pradeep said. He and a team of students formed a company to keep up with the work,he added.

            The device（設(shè)備） come in two sizes and at three price levels,which include installation (安裝) costs: The $16 version is for homes; a larger one that can be used at schools and office buildings is $500 (connecting a whole village costs $700 more) . The larger purifier,which stands nine feet tall,produces about 80 gallons of clean water per hour.

            Worldwide,663 million people do not have access to clean and safe water. In India,access to clean water is particularly poor. About 21  percent of illnesses in India are caused by drinking dirty water,and more than 100,000 deaths are caused by water-borne illnesses each year.

           The first of Pradeep‘s  pumps was "installed in West Bengal,a state in eastern India,in 2012. The state government took notice and installed pumps at 330 schools across the region. As a result,now about 500,000 people have access to clean water from these pumps,said Pradeep.

However slie noticed how difficult it was for her dad to remain awake while driving back from ?ieir femiiy vacations in Florida to their home in Maryland. Her mom had to talk to her dad all the way.

The 吵對撕(系統(tǒng)) then gives warnings,if needed. As the driver becomes sleepier,red color will be shown to warn him or her. The driver will also hear messages warning him to get off the road. The machine can say, “You’ re tired. Please take a break."

      After sending her invention to the 2014 Discovery Education 3M Young Scientist Challenge,Wu was chosen as a finalist and was able to work with Dr. Jesse Miller,who is a product development specialist.

As a young scientist,Wu has some advice for other students of her age: ul would like to tell them that they should choose something they* re interested in. So they 11 be willing to spend more time on it and enjoy working on it more. Also when there 's difficulty,they should just continue working hard because they’ 11 get over it."
