Johann Kailey-Steiner is a freshman at South High School in Denver and has already won a national award, met the president and will give a TEDx talk all because of his research into making rockets more efficient.
Kailey-Steiner has designed an add-on, called a vortex generator, that appears to improve the performance of rockets by reducing drag and improving fuel efficiency. He’s preparing for his first TEDx talk on Wednesday.
