| Jun 23, 2021 at 17:21 | comment | added | Cleonis | @d_b I concur with the discussion by Kevin Zhou Blackbird was the subject of one of the questions of the 2013 Physics Olympiad. In the solutions to the questions Kevin Zhou writes in boldface: "the downwind case. [...] power is transferred from the wheels to the propeller." It's unclear however, whether Derek Muller understands this explanation. From the youtube video I cannot tell whether Muller (and the people who built the vehicle) understand what is going on. They appear to be on the wrong track. | |
| Jun 22, 2021 at 21:47 | comment | added | d_b | Before answering how this can happen, I think it should be noted that there is ongoing debate as to whether it does happen at all. I refer you to Derek Muller's (twitter.com/veritasium) and physicist Alex Kusenko's (twitter.com/alexkusenko) Twitter pages. Muller has made a $10k wager with Kusenko in this matter, and as far as I can tell the bet has not yet been settled. | |

| Jun 1, 2021 at 18:33 | comment | added | jalex | @Cleonis - I was going to try to create a mathematical model of the vehicle, but then I read this (aviation.stackexchange.com/a/10032) and decided it would be too difficult to generalize/simplify. | |

Rewrite: explicit announcement the question is preparation for self-answer.
