- theli0nheart 5y agoI thought the video below provided a good explanation for why this works. The physics are similar to those of a single sailboat going faster than the wind. Imagine two sailboats on a cylindrical ocean on diagonal tacks, on opposite poles, and rotating around the core with rods connecting them to the core. Now you have a propeller. :) https://www.youtube.com/watch?v=jyQwgBAaBag&t=404s https://www.youtube.com/watch?v=jyQwgBAaBag&t=404s
