Are electric cars good for the Earth? Many of us would probably say yes. But Robert Sansone knows the answer to that question isn't that simple. Many people call Sansone a natural-born engineer. It is not surprising if you look at what the boy has done. The 17-year-old has completed nearly 60 engineering projects in his free time.

A couple of years ago, Sansone watched a video about the advantages and disadvantages of electric cars. The video explained how the motors of these cars are made. Most of them use rare-earth metals(稀土金属). These materials are very expensive. They cost hundreds of dollars per kilogram. Even worse, they are often collected in ways that are harmful to the Earth. "Must we use these metals? Is there a more environmentally-friendly way to make electric motors?" Sansone thought. He had heard of the synchronous reluctance motor(同步电动机) before. But its performance should be improved.

Over the following year, Sansone put one design after another to the test. Things didn't go well at first. He failed fourteen times before coming up with a working model. The model is about 40% more powerful than a traditional one. And it doesn't make use of rare-earth metals. These efforts have earned Sansone a big award. The teenager took part in this year's Regeneron International Science and Engineering Fair with his motor. It is the world's largest pre-college science competition. He stood out from among more than 1,800 competitors to win first prize.

Sansone, however, isn't yet done with his invention because it is far from perfect. There is still a big problem: It is difficult to make. This means it is not very likely to become widely used. So Sansone has continued to improve and test his motor. Hopefully Sansone's design will completely change the electric car industry one day.
