Timeline for The nice Veritasium video about a wind-powered vehicle that can go downwind faster than the wind itself

| Jun 1, 2021 at 17:08 | comment | added | Cleonis | @JAlex I believe there is a key point as to what is different from moving into headwind and moving forward, going downwind. When this vehicle is moving into a headwind, powered by the wind, then the wind is turning the blades and that power then flows to the wheels. When moving downwind that powerflow must be the reverse, otherwise what is shown in the video would not happen. It must be the case, I believe, that when moving downwind the wheels are powering the blades. Everything else follows from that. | |

I removed a paragraph that I think is an error.
