Japan's Plan For World's Tallest Building
Inspired by Mount Fuji, Taisei Construction Corporation has completed designs for construction of the world's tallest building. The X-Seed 4000 would stand at approximately 13,123 feet (4 km), nearly 700 feet (213 m) taller than the real Mount Fuji. The next tallest buildings don't even break 2,000 feet, how puny! While likely to never be built, the X-Seed would have up to 800 floors, and be capable of housing between 500,000 and 1,000,000 people.
Unlike conventional skyscrapers, the X-Seed 4000 would be required to actively protect its occupants from considerable air pressure gradations and weather fluctuations along its massive elevation. Its design calls for the use of solar power to maintain internal environmental conditions. Some estimate that the cost to construct the X-Seed 4000 structure may be somewhere between $300-900 billion US dollars.
Now I'm no astronomer or anything, but if I learned anything in grade school, it's that 13,123 feet is pretty much the distance to the sun. Which means that the top floor would be perfect for a natural sauna. You heard it here first, if they end up doing that I want credit.
A few more conceptual pictures after the jump.
