At the age of 13, a boy living in Sierra Leone created batteries and generators using materials he picked up around the house or from trash bins. Now, he’s wowing experts in the U.S.，Kelvin Doe became the youngest person in history to be invited to the “Visiting Practitioner’s Program” at MIT, according to CNN. 

年龄仅仅十三岁，在塞拉利昂的男孩用在家里和垃圾桶捡的材料制造了电池和发电机。现在已经被美国专家刮目相看了。根据CNN报道，开尔文已经是历史上最年轻被邀请去麻省理工大学参加“Visiting Practitioner‘s Program”。

Kelvin, a completely self-taught engineer, manages his own fully-staffed community radio station in Sierra Leone where he broadcasts news and plays music under the moniker ‘DJ Focus.’ The radion station is powered by a generator created from a deteriorating voltage stabilizer, which he found in the trash, while a simple antenna lets his neighborhood listen in.

开尔文是完全自学的工程师，他在塞拉利昂有自己的地区广播电台，在这里他广播新闻，他还以“DJ Focus”的小名播放音乐。他的广播台是用他自己制造的发电机，这发电机是他从垃圾捡的坏了的稳压器，他还配了一个天线播出信号让他的邻居们听。

“They call me DJ Focus because I believe if you focus, you can do an invention perfectly,” Doe said in a video produced by @radical.media for their THNKR YouTube channel. Among those inventions is a battery that he created to light up homes in his neighborhood.

“他们叫我‘DJ Focus’是因为我相信如果你集中注意力你可以完美的发明你想发明的东西“ 他在一个采访他的Youtube频道说。他的发明包括电池，这个帮助了他的家周围提供电力开灯。

It took several attempts before Kelvin finally had a working prototype for the battery — a combination of soda, acid and metal, wrapped together by tape.

为了制造这块电池开尔文试图了各种方式才做到一个可以工作的电池-他用了苏打，酸和金属并用胶带绑一起。

MIT discovered Kelvin during Innovate Salone, a national high school innovation challenge held in Sierra Leone by an international organization called Global Minimum. Doctoral student David Sengeh recognized his skills right away.“It’s very inspirational,” David said in the video. 

麻省理工大学经过Salone节目发现了开尔文，这个节目是在塞拉利昂国家高中发明家挑战比赛通过一个叫“Global Minimum”的机构举办的。一个博士生大卫一看他就发现了他的才艺。“非常有激励人的”大卫说。

Before attending Innovate Salone that year, he had never been more than 10 miles from home. With David’s help, in September he journeyed to New York for the 2012 World Maker Faire, where he sat on a “Meet the Young Makers” panel with four American inventors.

参加这个节目之前，他从来没有离开家超过10英里。通过大卫的帮助，他参加了2012年纽约“World Maker Faire”，这里他跟四个美国年轻发明家一块参加“碰见年轻的发明家”节目。

Kelvin’s fame only promises to grow from here. Soon he will be a resident practitioner with the International Development Initiative at MIT and a guest presenter at Harvard School of Engineering, where he’ll gain even more practical knowledge to help his community. 

开尔文的路程是从这里开始。不久后他会变成麻省理工大学里面举办的活动的常客而且它还会在哈佛大学工程学院的嘉宾主持人，这里他会获得更多实用知识。

“Whatever things I’ve learned here, I will share it with my friends, colleagues and loved ones,” Kelvin said.

“我在这里所学的东西，我会更我的朋友们，同时和亲们分享”。开尔文说
