14.Hannah Herbst,a 15-year-old teenager from Florida,US,has just become America's Top Young Scientist.She was given this award (奖赏)for her invention which turns ocean (海洋) energy into electricity for the developing world.
In fact,Hannah was just a middle school student before that.She came up with this idea because of a letter from Africa.Shortly after the school began in 2014,she received a letter from her 9-year-old pen friend,Rose,in Africa.In the letter,she told Hannah that her family didn't have enough fresh water or electricity.Hannah realized that Rose's situation was bad and in some developing countries some people were in the same situation.She really wanted to help them,so she decided to do something useful.
Hannah began to work on her invention called"BEACON"to produce electricity from ocean power.Luckily,her idea won the attention of Discovery Education 3M Young Scientist Challenge.She got the opportunity to work with a scientist to improve her invention.Thanks to this project,she won a prize of 25,000•She offered to donate (捐赠)half of the prize to people in need of energy in developing countries and planned to keep working on BEACON to improve the real life situation.
Bill Goodwyn,the CEO of Discovery Education said,"It is always encouraging to see young people like Hannah use their skills to solve real problems and make changes for the better life of people."Millions of American students have a"scientist dream",but Hannah was the few ones who could realize their goals.She wrote in her blog (博客),"It was so great to see my ideas come to life.I knew that it was hard to begin with,but I kept working and never gave up.After successfully creating BEACON,my love for science was discovered.I hope others will find their interests and make their dreams come true.
