i think the biggest difficulty is heavy regulations to prevent anyone from attempting anything. saw a video the other day where there was a comm7nity of people living in house boats within a bay of a particular city but suddenly rich people with mansions along the coast decided to lobby for regulations to get rid of the houseboats in the bay. the houseboat people weren't vagrants either. they just simply chose to live in boats in the bay but suddenly some other people decided they needed to go.

[@Libertaro-i2u]

One potential solution would be to make the houseboats seaworthy and live primarily or exclusively in international waters. Though even this presents a lot of legal hurdles because according to international law, all manmade objects in international waters are required to register and fly the flag on an existing nation-state, quite the problem if you're looking to test new governance systems.

[@gusty7153]

On the other hand, countries that are facing dissappearance like Maldives or some Pacific coral islands, might be way more amenable to relaxing regulations, because they might need these solutions for their own survival. I wonder why no partnership between seasteaders and the government of those countries has arisen yet, since it would provide real benefits to both.

[@gusty7153]

@@bassmanjr100 Oh, absolutely, definitely don't wait for life to happen "one distant day"! I get where you are coming from, there's definitely been a time where I was basically "living for the future", so thank you for bringing that problem up! At the same time, I can be looking forward to something without it detracting from my experience in the Now, if "looking forward" isn't the only positive thing I am experiencing. And if someone were to be sad because of a feeling of "missing out on the future", why not look at the trends and possible futures and see the possibility of bright things there, too? (And - I really don't mean to imply that you are in that position - in principle one can be just as escapist by "living as much as possible in the Now, and every moment that I look forward or backwards is wasted", as they can be with "I can't live in the Now, because it is terrible, let me look forward into the distant future to the possibility of something good happening." I don't think the looking in itself is the problem. But again, thank you for highlighting the option of escapism!) All the best

The idea method of powering floating cities would be ocean thermal energy conversion, or OTEC for short. You pump cold deep water to the warm surface to power what's essentially a low-temperature steam engine. Also creates an artificial upwelling zone, so there's your food source, and distilled water as a byproduct. It's most efficient in tropical temperatures, ideally within 5 degrees of the Equator. These spots in the oceans are called "the Doldrums" due to the calm weather so there's the storm problem solved as well. Again, I suggest giving the Living Universe Foundation's web site a look, particularly the Aquarius section. : )

[@yjlom]

OTEC is quite bad at actually producing power though and would probably have to be suplemented by solar or nuclear but the "byproducts" are what makes it worth it

[@st3llarmemer111]

Something interesting is that based on: - Most planets being smaller - Smaller planets only holding onto oceans at a younger age The majority of terran worlds in the universe would be smaller proto-earth analogs, and this would be even moreso around larger A-type stars where we would expect a high frequency of giant planets and moon systems (where a moon may only be as large as mars) but also shorter stellar lifetimes (which would nullify lower ocean lifetime as a negative for smaller worlds). On the other hand, due to their flaring nature, smaller M-dwarfs would only have larger terran worlds. This effectively creates an inverse correlation between star size and terran world size, where the larger a star is, the smaller terran world we'd expect

[@skyhawk551]

Using electroplating to form "seacrete" you can also grow your structures from the ocean using rebar as the annode and create structures with the same compressive strength as normal concrete in a month. Float out a raft of solar panels and hang a structure skeleton underneath and grow your floating island in chunks.

Depending on where, islands in straits, there can be an effect on ocean currents.

[@johnpye-d2n]

Breaking up the inaccessible continental land by building inland oceans is a more practical solution. That material could then be used to build islands and expand coastlines with bays. Continental climate stabilization would be an added benefit.

[@Libertaro-i2u]

Although that wouldn't be an option geopolitically except maybe in Australia, all other continents are divided into multiple nation-states.

When talking about knocking down mountains, you can't for get the weather effects. One of the reasons Africa has such unpredictable weather is due to so few mountain ranges to stop clouds reliably in the same areas. If you go knocking down too many mountains, you eliminate the stability created by the mountain shadow effect.

Seasteading (on Earth, anyway) is hit by a lot more regulations than you might expect - and certainly more than the people who've tried it expected (the 'Adam Something' channel has some videos on this, and related things, though he's pretty cynical, as well). It's still worth discussing, but the fact that you can't totally escape regulations that way, and that it's more expensive than it seems, should not be ignored.

[@Libertaro-i2u]

The main regulatory problem is international law, which requires all artificial objects in international waters to fly the flag of an existing nation-state and be subject to the laws thereof.

[@comentedonakeyboard]

If you escape regulations, they will just expand the regulations.

[@princecharon]

@@Libertaro-i2u Yeah. I feel like 'be subject to the laws thereof' is the part that a lot of the would-be seasteaders don't like when they find out. It's less of a problem when one doesn't object to obeying the law, though.

[@acadiano10]

Lots of possibilities including dystopian ones. Colonies either at sea or on other planets will need labor and safety regulations unless you want some abrupt changes in leadership.

I think the best model for the culture of a colony on an ocean world would be one that has a long and extensive maritime history. While the Polynesian peoples (Samoans, Maori, Hawaiians, etc.) and the Phoenecians make the obvious choices, the Bajau nomads of the South China Sea (who until the governments in the region largely forced them to settle down were born, lived, and died at sea) would be excellent for another reason entirely - they are biologically adapted to be freedivers. Their bodies tend to be very lean, allowing them to achieve negative buoyancy on their own, and they have a spleen 50% larger than a typical human's which allows them to have a higher blood oxygen level for longer (some of them have been recorded to hold their breaths for as long as 13 minutes, and even when spearfishing they'll stay underwater for minutes at a time. Some Bajau children make money diving for coins that tourists throw overboard). This second trait is something I could also see being genetically engineered into spacers to make them better at surviving mishaps, so it wouldn't be a stretch for spacers looking to settle down to choose an ocean world to start their colony, and if spacer culture is Bajau-adjacent because of the similarity of their environments, then something of them would survive the forced settlements and the ravages of climate change.
