- The Space Elevator is a
hypothetical structure that would consist of an approximately long
cable connecting a point on or near the equator to an object,
possibly a captured asteroid, in geostationary orbit.
- The Launch loop concept has been
proposed for the purposes of orbital launch which would be 80 km
high, and would have a cost of around $10 billion.
- The X-Seed 4000 is the tallest
building ever imagined. The X-Seed 4000 "was never meant to be

Data, a firm which compiles data banks on buildings worldwide. "The
purpose of the plan was to earn some recognition for the firm, and
it worked." Its proposed 4,000 m (13,123 ft) height, 6 km (3.7 mi)
wide sea-base, and 800 floor capacity could accommodate five
hundred thousand to one million inhabitants.

Japan metropolitan area. The plan consists of a building 1,000 m
(3,281 ft) tall and 400 m (1,312 ft) wide at the base, and a total
floor area of 8 km² (3.1 sq mi).

between 600 and 610 metres are planned according to FCC-database.
