Leonardo Da Vinci designed an aerial screw that looked like a helicopter in the 1480s. That's over 400 years before the first helicopter and even before the first engine! Engineer students replicated his design and found it actually produces lift. It's even more efficient as it produces less downwash. Da Vinci was never able to build or test his design. And yet, it works! He was centuries ahead of his time. 💌 My newsletter
