Our Future of Living on the Water - Floating Cities?

As someone who owned a sailboat for 10 years, I can say maintenance of anything on the water will be a bee-yatch. It's even worse if you can't pull it from the water. I can imagine vast swaths of sea growth hanging from the underside, probing and widening microscopic cracks. So for example that illustration of neatly hanging lines of kelp will either require regular undersea pruning by divers, or it will look like a complete mess. Also, universally articles like this never present realistic reviewed projections of anticipated costs. For example, would electrochemically generated sea-ment cost less per pound than using more conventional options, or is the assumption that the ecofriendly electricty would be so plentiful, that it would not bet better used for another purpose, like desalination? I'm not against this idea, I'm just pointing out questions that any savvy investor would ask.

As an islander, I think the design and concept is beautiful, awesome and inspiring but VERY IMPRACTICAL.. The problems we often had: 1. Medical Emergencies- Hospitals are not that reliable. We had to take a boat in order to get to somewhere else and people often die on transit. 2. Cost of living- basic goods are way expensive because you literally need to import it from somewhere else. Supplies are limited and delays in shipments. 3. Isolation- the feeling that you are left-out from the rest of the world. 4. Maintenance of Structure- sea-salt is very good at rotting away stuff.. 5. Economy- no good paying jobs because there are no big companies around due to limited space and low population. And many more.. Proposal- Japanese strategy, they cut half top of a mountain and turned it into a city. The rest of the soil used to extend elevate the flood-prone shores. It's way more sufficient, practical, feasible and less cost than floating island. The floating island idea is already hostorically ancient.

[@extropiantranshuman]

1) I think we have to realize that in certain ways, people are less likely to be ill there. I mean they could get sea sick, etc. - but overall they're isolated and immune. 2) if cargo ships pass by you all the time - it's going to be the cheapest place to ship - not to mention eco-friendly! 3) yes, that's true - but I don't see them in the middle of the ocean, but by shore. I mean if they're large enough - I don't see that happening - it's as isolating as living in a city - as we live on Earth - which is the most isolated planet from life of anything. With the pandemic and the internet - people are either used to it or can find ways to stay connected anywhere. 4) well maybe there's a way to avoid that by storing fresh water around it - and having a coating. I mean salt is great for electrolysis - I bet it's going to lead to salt crystals keepng the place intact - not to mention a lack of maintenance if it's a self-healing structure. I feel if it's made with materials taht're of the ocean - like kelp - and these don't degrade from salt - why would your structure? 5) it's very likely the large companies would be able to afford a place like this - like dubai did - so I bet high paying, remote work jobs would be here. I highly believe top workers who are used to remote work would live here. Of course if you're moving a city with average citizens - it's the opposite That makes sense if you have a mountain to begin iwth - but most places flooded out don't have those. Also you don't have to cut a mountain in half - you can just live on top or the side of it - like I do! Poor mountain.

While I find the concept intriguing, as a naval architect with more than 45 years of experience designing things to survive whatever the ocean can throw at them, I strongly urge people not to underestimate the power of the sea. And remember, there is no such thing as an unsinkable ship, so I suspect there is no such thing as an unsinkable (part) of a floating city. One thing I am concerned about is that any structure moored to the bottom with a fixed-length system, like the one illustrated for seacrete, would be unable to move in response to wave action and could be subject to what we call "green water" - waves sweeping across the "deck" which looks to me like "ground level". The forces are enormous, and non of the structures shown in the artist's conception would be likely to survive. Could this work? Absolutely, if enough proper engineering talent - and money is applied.

[@illdeletethismusic]

for the last part, yes, this would likely require sturdy walls, more similar to the sides of cargo ships than the utopia shown in the renderings on the sides exposed to the outside. sides only exposed to water between the islands could work similar to what"s shown as long as the mooring is fixed length and the structures act sufficiently as wave breakers. as for taking up the forces, that would obviously be easier with looser moorings, but then the wave breaking effect would mostly be gone

[@t_c5266]

I'm not sure I understand the concern. The only reason this is a problem is because people have some overblown ideal of being coastal. Distribution of people throughout the country is the solution, not increasing the capacity to concentrate at the coast. Wyoming, Montana, the dakotas, new mexico, Idaho, etc. all have 10x less people per square mile than California, who already has an amazing amount of unused inland. The best part of this solution is its completely free, and would even benefit the usa and each state that got more population boost from this strategy. Not to mention we wouldn't have to build any of these complicated water harvesting systems or engineer around storms. Or we can concentrate at the coasts and spend $400 billion on building walls (walls we cant even manage to build on solid land at the border)

[@Youbetternowatchthis]

@@jeremiah6462 There is more to it than that. The waves a hurrican can produce can get poerful enough to slam holes into solid steel ships. You can look that up. It is actually quite frightening in my opinion. (also check out freak waves if you need even more terror) A floating city could be built to withstand such forces maybe, since oil rigs are pretty tough and exist already. But nothing just shrugs off a a hurricane at sea. Even the most modern ships can sink in bad weather conditions. Oh and conditions are getting worse since we heat everything up and put more energy into the system. Getting the frack out before a hurricane strikes will always be the best option.

Yet another climate hysteri....crisis scam to steal peoples funds to elites pockets just like emission taxes. For instance Finland should be receiving shit ton on money for being Europes lungs with amount of forest, but no we need to keep paying and be taxed hell and back to point where its very difficult to even go to work due gas prices and taxes added to that.

Countries like Germany are in this list but refuse to use/add the only alternative nuclear energy and when you want to have the more safer and cleaner variant like molten-salt reactors . You would have needed to start with the development 20 years ago. On top of that in most countries the power grid isn't able to resist this much energy when you use everything 100% electric. The real core problem is people are living in absolute denial of reality and when you mentioned e.g in Germany that they need nuclear energy you get stoned

I know this is off-topic but... I think we can use ram pumps to solve the energy crisis. First we build a hollow cylindrical tower out at sea, to a depth of say 1100m. The tower is open to the air at the top and has a sealed base at the bottom. We drill a hole about 20m below the surface and feed water into the tower. The water falls down a pipe for about 200m where it powers a turbine that is connected to an electricity generator. We collect the water and drop it down a pipe for another 200m to another turbine. We do this twice more until we are getting electricity from four generators. We then drop the water another 200m to power a turbine which drives a cog that is geared to turn a disc at the base of the tower. The waste water from the last turbine starts to collect at the bottom of the tower creating a shallow reservoir that we need to pump out. The rotating disc at the base of the tower has cams along its edge. These cams are used to push pistons outwards. These pistons are in cylinders built into the wall in a circular formation. The cylinders are sealed at the interior side apart from where a piston rod enters to push the piston outward. The outside of the piston head is exposed to the deep sea water. The cam will push the piston outward against the high pressure deep sea water. An inlet pipe will take water from our shallow reservoir which will be pulled into the space created in the cylinder, behind the piston head. When the cam releases the piston, the low pressure water inside the cylinder will be the only thing pushing the piston out against the high pressure deep sea water. This is when the system acts as a ram pump. The piston will be forced inward and will force the low pressure water back out through the inlet pipe toward the reservoir. The inlet pipe will now act the same as a waste pipe in a ram pump and the flowing water will shut a waste valve. The remaining water in the cylinder will be forced through a check valve into a pipe and upwards to the surface. The larger the diameter of the tower, the more cylinders that can be built into the wall at the base of the tower. I realise that the ram pump cylinder will pump more of its water back into the reservoir than it sends to the surface but we can always add more cylinders to the system. We can even put another layer of cylinders above the original ones as ram pumps still work underneath shallow water. I think we should be able to pump water upwards at the same rate that it falls into the bottom of the tower and so keep the reservoir nice and shallow. Now, if I understand the maths correctly, we might only be able to pump the water near to the surface. In that case, we can pump the water into a reservoir tank (inside the tower) and use the electricity generated by the first turbine to pump out the tank. This will leave us with 3 generators worth of electricity for every tower built. Would this work? Everyone, please comment.

[@Kevin_Street]

I love this idea, because it feels so much like a video game. But at the same time it's clear that it's _very_ early days for floating cities, and there's an awful lot of problems that will need to be solved before they could work as true cities. No doubt that's why the SeaSteading guys are only talking about building expensive single "pods" and not whole communities. I'm really interested in the Oceanix project and hope they actually build it. In Southeast Asia they've had floating villages and neighborhoods for centuries. For instance lake Tonle Sap in Cambodia has hundreds of little floating fishing villages. But these places tend to be inhabited by the poorest of the poor who depend upon resource extraction to survive. Or in the case of floating neighborhoods, they tend to be the poorest and most desperate parts of the slums, were people locate because their semi legal-status means residents don't have to pay property taxes. If an American city that's threatened by climate change - like say, Miami - was able to transform itself using this technology and became partially floating and partially on land, how would the floating sections avoid the long term pressures that tend to turn floating neighborhoods into slums? Would people with money want to live on the floating parts, or would everybody be competing to live on land?

These guys right here seem to have the same issue, those city graphics does not look nothing similar to oil rigs, so their point that "oil rigs" can survive ocean, it does not proof that their cities also can, because those cities are super low and they do not enter in detail on how they will deal with waves or the extra cost of all the structure or objects in order to deal with the constant movement, of course there are ways to solve all that, but not at low cost. Their idea to extract energy from the water gradient is also silly, the gradient is so low that it would take a huge investment to extract very little power, when solar panels and wind turbines (or kites) would be close to one order of magnitude cheaper, using hydrogen as the main energy storage to solve power intermittence.

After it's burnt then it can be emptied into the ocean. I'd love to live another 100 years. Maybe I could do something in that span to be productive for humankind.
