17-Year-Old Designs a Motor That Could Change How Electric Cars Are Made
Electric cars are helping us forge a more eco-friendly future. However, one environmental and design barrier to truly easy, sustainable-to-produce cars is the motors. Most electric vehicle (EV) motors use rare-earth elements in their internal magnets which generate the required torque to power the motor. These elements—including neodymium, samarium, and dysprosium—are very expensive and their mining is detrimental to the environment.
