Experimental Cities Part 2: Seasteading

Alex Tabarrock offered a good summary of this movement/vision over at Marginal Revolution a while back.  As he points out, it touches on many of the same governance-related themes as the Charter Cities idea. From a design perspective, these cities-at-sea could be paradise islands for anti-automobile planner-types (which would make for an interesting mix of residents, as many of the early supporters have been libertarian-leaning). Actually, The Seasteading Institute has already held an architectural design competition. Looks like the topic could provide some entertaining exercises for all of you Sketchup artists...

Finding Atlantis

Interesting description of how the ocean floor is mapped.

Some have speculated that these are the plow marks of seafloor farming by aliens. If there really are little green men hiding somewhere, the ocean's not a bad place to do it. Mars, Venus, the moon, and even some asteroids are mapped at far higher resolution than our own oceans (the global map of Mars is about 250 times as accurate as the global map of our own ocean).
