They grow on the sides......No, increasing the height of a building changes nothing, ON AVERAGE. Where you might have more light capture on the east side in the morning, you have darkness after noon. That morning light capture comes at the expense of the neighbor's building getting no light at all.
Let us consider that dinky building relying on sunlight to penetrate it's multi-story structure to capture photosynthesis, as shown in the original picture. If it has no neighbors of similar height, then it is only stealing its neighbor's sunlight. Surround it with other buildings like itself, and it cannot get any rays except on the roof. I do not believe that isolated buildings of great height offer any agricultural efficiency advantage over plain old flat ground except where sunlight will be supplemented with artificial light. And all known artificial light comes with a huge energy expense greater than the lumens of light produced.
As to more light by increasing the height? Assume a large area, rather than one tiny building in one little spot. Imagine, if you can, a square mile of field. Then tell me that more sunlight falls upon that field when it occurs at a higher altitude.
Sadly, this just seems to be another case where the quote just ain't so.
That whole graphic is very much a misleading piece of information. Maize is a very high producer of oxygen, but that tidbit of information is unrelated to the image shown. The graphic image is only showing "fluorescent" light as a consequence of photosynthesis. What isn't explained or evaluated is that no comparison has been shown in this article as to how much relative "fluorescent" light is produced by different types of vegetation. A careful look at the video also shows that they are showing similar light flares where corn is never grown.That is really deceiving. Comparing peak to average. Corn only lives for about 4 months and probably only near its peak for a couple of weeks. We have the old saying around here, "the corn should be knee high by July".
The person who did this layout needs to be shot.
What's my cut on all this gambling?
