Where can we build tall buildings?
How many meters can we build high buildings?
In the last two centuries, people have continuously built incredible buildings, from the Eiffel Tower to the Empire State building in the US, all of which are over 300 meters high. Currently, the world's tallest building is 828m high.
Burj Khalifa building.
So how many meters can we build high buildings?
In theory, just enough materials to meet, we can build the height at will.
However, in fact, the tallest building in the human world can build about 4000m high, has the same structure as the Eiffel Tower, the lower floor extends, the higher the height, the more narrow it to reduce the power wind.
However, at a height of 4000m the wind will knock down any construction. Elevator system is also a problem. With a 1000m high building will need 600m of cable. More than 2400 meters of cables are too heavy to operate.
On the other hand, it needs an area of 6km 2 and the amount to build is more than 400 billion USD.
