Wired has now written about seasteading. Peter Thiel Makes Down Payment on Libertarian Ocean Colonies:
Instead of starting with a grand scheme worthy of a James Bond villain, the Institute is bringing an entrepreneurial, DIY mentality to creating oceanic city-states.“There’s a history of a lot of crazy people trying this sort of thing, and the idea is to do it in a way that’s not crazy,” said Joe Lonsdale, the institute’s chairman and a principal at Clarium Capital Management, a multibillion-dollar hedge fund.
The seasteaders want to build their first prototype for a few million dollars, by scaling down
In essence, the seastead would consist of a reinforced concrete tube with external ballasts at the bottom that could be filled with air or water to raise or lower the living platform on top.
The spar design helps offshore platforms better withstand the onslaught of powerful ocean waves by minimizing the amount of structure that is exposed to their energy.
“You have very little cross-sectional interaction with waves [with] the spar design,” Gramlich said.
The primary living space, about 300 square feet per person, would be inside the tube, but the duo envisions the top platform holding buildings, gardens, solar panels, wind turbines and (of course) satellites for internet access.
To some extent, they believe the outfittings for the seastead will be dependent on the business model, say aquaculture or tourism, that will support it and the number of people aboard.
“We’re not trying to pick the one strategy because we think there will be multiple people who want one for multiple reasons,” Gramlich said.
Dan Donovan, a long-time spokesman for Dominion, an energy company that operated Gulf of Mexico-based gas rigs, including Devils Tower, the world’s deepest spar structure, said the group’s plan wasn’t too far-fetched. His company’s off-shore rigs, which are much larger than the institute’s planned seasteads, provided long-term housing for its workers.
“They were sort of like mobile homes. We could move them from one place to another,” Donovan said. “People did live on them.”
