Hat Tip to Larry Niven
In the book Ringwold and its sequels, Larry Niven wrote of an artifact-world so large that 1:1 scale models of various planets, like earth, were created as islands in its vast oceans. Not quite 1:1, but here is the same idea:
The World is a man-made archipelago of 300 islands in the shape of a
world map. The World is being built primarily using sand dredged from
the sea. Each island ranges from 23,000 m2 to 84,000 m2
(250,000"“900,000 square feet or 5.7"“21 acres) in size, with 50"“100 m of
water between each island. The development will cover an area of 9 km
in length and 6 km in width, surrounded by an oval breakwater. The only
means of transport between the islands will be by boat and helicopter.
Prices for the islands will range from $15-45 million (USD). The
average price for an island will be around $25 million (USD). Dredging
started in 2004 and as of March of 2007 The World is around 90%
complete.
Update: I have long contended that, at least if you eliminate all entries from the list involving women, that owning an island is the ultimate male fantasy. Also a good way to "short" global warming predictions, if you are so inclined
