"synchronous reluctance motor that had greater rotational force—or torque—and efficiency than existing ones. The prototype was made from 3-D printed plastic, copper wires and a steel rotor and tested using a variety of meters to measure power and a laser tachometer to determine the motor’s rotational speed. His work earned him first prize, and $75,000 in winnings, at this year’s Regeneron International Science and Engineering Fair (ISEF), the largest international high school STEM competition"
