Jeff Chan gave an interesting presentation at the recent conference about Seadrome, an ocean platform design created back in the 30′s as an airplane refueling stop. It was never built due to increased aircraft range, but the design still serves as a good example of how to build a spar platform for the open ocean.
Check out the [wiki page on Seadrome](http://wiki.seasteading.org/index.php/User:Jeff_Chan/Seadrome), and the [PDF of his conference talk](http://www.jeffchan.com/seasteading/conference/2009/seadrome/Spar_buoys_Clubstead_Semi_submersible_oil_pl.pdf). He focused on the common elements between Seadrome, ClubStead, and other designs, as an indication of how best to approach the spar platform portion of the design space. As with other talks, we’ll be putting this talk online later this year once the slides have been edited into the video.

As [ClubStead](http://seasteading.org/strategic-areas/engineering/clubstead) gets wrapped up, I’ve been pondering the next steps for our structure development. ClubStead demonstrates that a spar platform seastead can be built which can endure the worst storms in a fixed location of California, at a certain price point. But we don’t want to demonstrate just via [engineering reports](http://seasteading.org/files/MIandT040_08_R1_Seastead_Exec_Sum.pdf), we want to do it by building prototypes. Continue reading

There has been a long and active debate about the relative merits of different structures for seasteading, such as [spar platforms](http://seasteading.org/book_beta/Above%20Water.html#floatingsparplatform), [breakwaters](http://seasteading.org/book_beta/On%20The%20Water.html#breakwaters), SFS (ranging from SWATH to spars to Water Walkers), sailing ships, or retrofitted cruise ships.

With the release of all the engineering documents on our [ClubStead page](http://seasteading.org/strategic-areas/engineering/clubstead), lots of questions have come up. For example, some people have pointed out that the topside weight and platform load are incompatible, and that there are negative airgaps in some of the big wave scenarios.
We believe strongly in the virtues of transparency, which is why we released the engineering information as soon as we could – right after the patent was filed – even though it isn’t complete. Continue reading

I’ve created [a hub for information about our ClubStead hotel/resort design](http://seasteading.org/strategic-areas/engineering/clubstead). It contains all the info posted so far, plus a SketchUp model for you to play with. Continue reading

- Added a box to the front page listing upcoming GTGs, with a module that automatically parses our Meetup.com Calendar. Yay for standards that let web services play nicely together!
- The German magazine Cicero: "Magazin Für Politische Kultur" is interested in doing an in-depth story this fall.
- Please use the wiki to keep technical notes after a discussion! Continue reading

A guest post from TSI co-founder Wayne Gramlich about his vision for the evolution of seastead communities:
My model for a seastead community is that it will grow and evolve along the same lines of Venice, Italy. Venice started off as 118 small shallow islands off the coast of Italy. In the beginning, passage between the islands was via small boats. Over time these islands became fully populated and interconnected via bridges. I expect a seastead community to follow a similar evolutionary path.
While it would be wonderful to have a fully interconnected seastead city at the outset, basic economics dictate that an initial seastead community will start off as a heterogeneous collection of individual seasteads. These seasteads will range from sailboats, old converted cargo ships, ocean going yachts, and purpose built seasteads. The purpose built seasteads will range from small to medium and eventually to quite large. The small seasteads will be short and squat and relatively low to the ocean surface. The more expensive and comfortable seasteads will extend upwards from the sea surface to reduce interaction with large waves. Eventually, large elevated surfaces along the lines of Mini-Float, Float, Inc., or VersaBuoy will become available. The larger structures will be either be bolted together or interconnected via bridges.

Check out Topsider Homes, builder of Hurricane-Proof homes in the southeastern US:
They are trying to solve a similar problem, and came up with a similar solution to us, which is good to see.
I got the link via Vince Cate’s great wavebreak page. Vince has been testing floating breakwater designs in Anguilla, and I’m pretty sure he’s done the most hands-on work so far, so good for him! One of the tricky things about breakwaters is that it isn’t always clear how their behavior scales, as discussed on the forums. We’re going to start talking to / hiring professional consultants in the coming weeks to flesh out our designs, so perhaps we can learn more about model testing from them.
