I've been contemplating the future potential for colonising the oceans; possible (high-tech) uses for abandoned oil rigs and massive cargo ships/bulk carriers. Some of the prospects they could offer have excited me for years: an transhuman level AI taking over a container ship and turning it into an advanced manufactury, or self contained, floating AI nation-state. Throw a few pampered humans on board too and you would have Banks' Culture on our high seas. As a main context for a sci-fi novel, it might make a great prequel to the Culture novels, much more interesting than a concluding story, as discussed in my
previous blog post.

Having contemplated technical solutions for autonomous living at sea as an purely hypothetical exercise (renewable power generation, pumping heat from the sea, growing plants and meat hydroponically, etc) I recently discovered the term "Seasteading", which represents a growing movement (and a revealing history).
One of the most famous Seasteads is "The Principality of Sealand", a former World War II 'Maunsell' Sea Fort in the North Sea, 6 miles off the coast of Suffolk (England). Despite consisting merely of two corroded pillars sticking out of the sea with a shack on top, it has currency, coins, stamps, national anthem and athletes, a constitutional monarchy that has issued tens of thousands of passports (now mostly revoked after fakes linked to high-profile crimes), broadcast pirate radio in the late 60s, 'defended' its territorial waters against the royal navy, witnessed a forcible takeover by a German and a Dutch citizen, who were later deposed and held as prisoners of war after a helicopter assault by the original owner (Bates), then freed after a diplomatic visit and now self declared "government in exile". Some of the highlights of
a truly hilarious Wikipedia article.

The point is having one's own 'land', free of big government, is exceedingly rare and desirable indeed! Dodging legalities for instance: The Pirate Bay attempted to
