In this vid and pic the yellow bases of the first row of turbines are not obscured. The eye level seems to be pretty close to the surface. I would say it's about 2m.
With an eye height of 2m, the horizon should be at 5.5 km. This means that according to the spheroid Earth's curve formula.......this pic must then have been taken within this 5.5 km distance.
Now you present this as evidence of the curvature of the Earth by pointing out that the turbines that are further away, in the second row, are being "cut off" from the bottom because they are being obscured by the curvature horizon.
Ok, so what is the distance between these rows?
The turbines are 749m-958m apart and installed in rows.
www.power-technology.com...
So the second row must then be within 6.5 km at which point you would get a hidden height of.........0.07 meters, aka 7cm.
These second row shafts, of 137 or 150 m high turbines(from bottom to blade tip) are almost being cut in half by the curvature you say?
When it should only be 7 cm?
Oops.
Again the supposed curvature fails.
At 7.5 km the hidden height would be 0.28 m. for the third row.
At 8.5 km it would be 0.62 m. for the fourth row.
It doesn't really matter what exact eye height and distance you take, with the max distances involved here, there simply isn't a large enough amount of drop across 1 km of surface to cut off almost half of the shaft of such a turbine, while leaving another turbine, 1 km closer, "untouched". Not even close.
However, the shot is probably taken from a further distance but according to Globe Earth math, the shot must have been taken within in 5.5 km of that first row of turbines, since they are not, or not noticably obscured by the horizon. If it was taken from much further away then at least the stretch between the camera and the first row of turbines, must be flat........
I like that Youtuber's comment in the vid description.
Exceptional clarity to view the windfarm as it drops over the horizon 22 miles away.
The horizon seems to be exactly at the base of the first row of turbines. If that is 22 miles away, then let me help you, at 22 miles, and a 2 m eyeheight, there should be a hidden height of 60m or about 200 ft.
We don't see any drop there. Nothing is obscured. If anyone wants to argue that I have the eye height wrong, and that it is much higher, then you will have the problem that the second row should not, or hardly be obscured either, it is only a km further away, and the third row is only 2 km further.
If you want to argue that he meant that the second row is at 22 miles, then the first row is still at 21 plus miles and the first row should still be obscured for a large part, but it isn't at all.

Conclusion, whatever it is that causes those views in the vid and the pic, is not a result of the supposed Earth curvature, there is no drop at all where there should be quite a lot, or there is way too much of it where it shouldn't be.(that much)
Take your pick.
The stuff you presented here as proof for a Globe Earth with a circumference of 24,901 miles, along with the supposed Globe Earth curvature math, actually disproves this belief.
The turbines are 749m-958m apart and installed in rows.
Pardon me while I point and laugh. If you can't be bothered to do your own research I'll be darned if I'm going to do it for you.

I care not for all the math involved in this,
Then don't interfere in a discussion that is based on this math.
I just want to see the edge and I'll straight up believe you.
I care not about your wishes. The discussion is about the Earth's curvature formula not applying to reallife observations.
Walney is constructed along a north-west to south-east direction. It covers an area of approximately 73km². Walney I and II each have 51 Siemens turbines with a rated capacity of 3.6MW. The turbines are 749m-958m apart and installed in rows. Turbines installed at Walney I have a rotor diameter of 107m and are 137m tall, to the tip of the blade. Walney II has turbines with a rotor diameter of 120m. The turbines have a maximum height of 150m to the tip of the blade.

When in Spain, I could see North African mountains on the horizon, but where is the rest of North African coast?
Another interesting question would be, "why can I even see this much of the mountains"? I agree that there is a phenomenon that is obscuring the lowest parts of the coast but there are other issues here.
The distance to the African coast is 160 km. Judging from the building visible in the pic and estimating the eye level from it, the eye height is about 50 m.
Eye level seems to be 8 storeys up, 8 x 4 m is 32 m plus another 10 m from ground to sea level is 42 m. Let's make this 50 m, I think it is actually lower, there is no way it is much higher anyway.
At an eye height of 50 m and a distance of 160 km, the hidden height would be 1119 m.
www.metabunk.org...
This has been corrected for refraction.
Here is an elevation map of North Africa.

As you can see, at 160 km, the highest visible peaks are around 2000 m high. It must be that mountain range nearest to the coast, because the mountains further away would be totally hidden by curvature, even though they are higher. So the part of the mountains we can see here should be 880m, max.
You really think you are seeing the top 880 m of 2000m high mountains there? It could be, but that looks out of proportion to me.
After I typed the above I decided to look for the location just by scrolling along the Spanish coast on GE, and I found it.
Coordinates,
N 36 34949
W 32 32057
GE gives an eye height of 37 m here, and this looks even higher than in the pic, it was probably taken from a hotel balcony.
I'll just stick to the 50 m eye height.
From this location the distance to the African coast is almost exactly 160 km. Those mountains are not located directly at the coast however. On the elevation map we can see that highest, 2000 m tops are AT LEAST 30 km inland.
So, a distance of 190 km with a generous eye height of 50 m would give a hidden height of 1781 m, this means that the part of the mountains we can see in the pic would be only 220 m. We all know that is not what we really see here.
At some points those mountains are actually 200 km away and you shouldn't be able to see them at all from that location.
Where's the curvature? Sure the very lowest parts are being obscured but this is probably due to atmospheric phenomena, not the supposed Earth curvature which I just debunked.
What are your excuses? Refraction? Already accounted for. So the only excuse you guys have left is...... "Mirage!".....
Which is ridiculous, since this view is always visible and that would be one persistent and stable mirage........
