South Dakota Students Win $10K for Fuel-efficient Invention
RAPID CITY, S.D. (AP) – Students at the South Dakota School of Mines and Technology have won two awards totaling $10,000 in prize money for an invention they say may improve vehicle fuel efficiency by up to 10%.
The Rapid City Journal reports that sophomores Mark Rotert and John Parker Chandler IV won a combined $5,000 Friday after pitching their vortex generator, TwisTech, in the governor’s Giant Vision competition. They also won another $5,000 prize from the college earlier this month for the invention to reduce drag on vehicles.
The students used a 3D printer to manufacture prototypes of the pocket-sized device. They say they’ve tested it on their personal cars, and used simulation software to test a digital model.
They say the invention yielded a 10% improvement in fuel consumption on sedan-style cars and a 7% improvement on semi-trucks.
