Following, Zhang Feng looked towards the notebook in his hand, and briefly flipped through his plan.
Currently, the goal of the mechanical platform is fifteen thousand meters high, already reaching the stratosphere.
The stratosphere is about twelve to fifty thousand meters above the ground.
Ultraviolet rays, even if absorbed mostly by the ozone layer and atmosphere, are still very sufficient.
The ozone layer is also within the stratosphere, but its height is between twenty to fifty thousand meters.
Takes a quick glance.
Zhang Feng did not feel that such 'high buildings' would cause any significant change in Earth's rotational speed.
Because this world also has similar theories to space elevators.
Zhang Feng once consulted Chen Genius, asking similar questions like 'Will an elevator extending so far from Earth change its rotation?'
For instance, when Earth is spinning around, suddenly a ten thousand ton object is sent to the top of the elevator.
