The Japanese are going BIG on this one!!!
The XSEED 4000 is currently on the drawing board for construction and if it receives the green light, will be the world's tallest populated structure at a whopping 13,000 feet. Just to put that into perspective, the current reigning champ is Taipei 101 at a mere 1,671 feet.
Not only is it destined to be the tallest but also the largest self-sustaining structure. Designed to look like Mount Fuji, the XSEED 4000 represents the Japanese view of a utopian society. The building will be powered by solar energy and can house up to 1 million inhabitants. As the Japanese islands become more crowded, engineers are finding new and extreme ways to build up. The whole project is estimated to cost anywhere from $300-900 billion U.S.
Seriously, did you really think the Japanese would just sit this one out? They are going big and if anyone can do it, the Japanese can.
I get dibbs on top bunk!!!
