This is the kind of silly design I was thinking of 25 years ago as I was cursing the headwind on the bikepath on my way home. Not the solar panel roof, but a straight up windmill mounted on my bike ๐Ÿ˜….

Doesn't it generate too much drag to be of any use?

you can gain energy while moving upwind, it makes more sense if you think about how boats can do a zig-zag to sail upwind (tacking).

Although the video they refer to in your link is about going faster in the direction of the wind, there is a cool explanation about tacking in it. Both great videos btw.
