in terms of
development and technologies?
While Elon Musk is trying to get people to Mars, Saudi Crown prince Mohammed bin Salman has plans of getting a different world on earth itself.
Imagine a science fiction type city with the same population as New York City with no roads, no cars and no pollution.
This 500 billion $ dream City alongside the Red sea is called The Line.
And this name is not without a reason, on the outside it looks like a 170 Km long but only 200 m wide wall made of mirrors.
This dream City will house 9 million residents with a footprint of 34 sq. Km.
It will be 500 m tall.
It will be taller than both the Eiffel Tower and the Empire State Building.
On the inside its 3D space will be structured such that residents can have access to all necessities within a 5 minute walking distance.
And high speed rails can take people from one end of the Line to another in 20 minutes.
Hence, no cars required so, zero emissions.
And all of it will be powered by renewable energy.
You could witness a part of it as early as 2030
