Robert Sansone’s research could pave the way for the sustainable manufacturing of electric vehicles that do not require rare-earth magnets
高校生Engineerが電気自動車に使われる、新しいコンセプトのMotorを開発。既存のRare Metal (希少金属)を使わない画期的な開発に成功したと言う、良い話題です。
Robert Sansone is a natural born engineer. From animatronic hands to high-speed running boots and a go-kart that can reach speeds of more than 70 miles per hour, the Fort Pierce, Florida-based inventor estimates he’s completed at least 60 engineering projects in his spare time. And he’s only 17 years old.
A couple years ago, Sansone came across a video about the advantages and disadvantages of electric cars. The video explained that most electric car motors require magnets made from rare-earth elements, which can be costly, both financially and environmentally, to extract. The rare-earth materials needed can cost hundreds of dollars per kilogram. In comparison, copper is worth $7.83 per kilogram.
