[@colliefields4637]

One Idea I saw regarding an Atlantic tunnel was to instead of going point-to-point from Great Britain to the North-Eastern United States, connect the two continents via the northern countries of Iceland, Greenland and Canada where they could in theory sacrifice time and directness for a lot more potential stops and passengers and theoretically less riskier to build and use thanks to the shallower seas and use of existing lands. Essentially it would go along the lines of: - Brussels to London via the Channel Tunnel (Brussels being the new "heart" of Europe in regards to railway connections). - London to Glasgow/Edinburgh, with possible stops around Manchester and Sheffield-Doncaster/Leeds for those wanting to be closer to the middle of the country. - Shoot off north-east before delving into an under sea tunnel taking the passengers to the Faroe Islands, saving costs via using the land briefly over there before returning to the seas until you reached Iceland and it's capital Rekjavik. -Another large underwater tunnel connecting Iceland to Greenland via the more shallow shelf and cutting through the land directly from east to west until you get to ther capital, Nuuk. - Straight across to Northern Canada, making a direct line south-west for Ottawa before finally making a turn to the North Eastern United States where it makes one of two more stops before finaly reaching New York City. It's a lot slower than London to New York direct, but it would theoretically be easier and safer to build and would have the added benefit of multiple countries being able to make good use of it without having to travel to London or New York City exclusively.

The video animations of the ship used in this video largely date from about 16 or 17 years ago (that's why the graphics look so poor).

A long time ago, I was a telephone installer. We were installing a PBX system in a very tall building and using a shaft to route the huge cable up through the shaft. We were lowering this huge cable filled with wire and then I noticed that the outside plastic sheathing was starting to stretch. I yelled up to the boss and told him to stop immediately. He came down to see why I had him stop. This was before cell phones BTW. We ended up driving anchors into the shaft and staggering the cable as it descended through the tie off straps to alleviate all that weight on any portion of the cable and then later on we tied it down. With the expanse of any structure from space, the weight along with earths gravity would make any structure unfeasible to do. You wouldn’t have any shaft to anchor the structure to it and I wouldn’t want to be on the ground when that shaft came crashing down from the sheer weight of the entire structure. Add into this Mother Nature with severe weather patterns, this thing would be a disaster waiting to happen. If you had structural problems in the areas where there is no air, how do you affect repairs? Even a space suit wouldn’t work.

[@toomanymarys7355]

Yes that's why it would have to taper and also why we need better carbon technology to make it work.

[@Me__Myself__and__I]

NASA has already done the research, its feasible we just can't quite make the carbon ribbons required yet. We can make them, but we can't make them long enough yet. There are competitions held with grant money to encourage work on the problem. Its been documented, research it.

[@timbert4672]

Such a structure would interact with earths natural electromagnetic fields too. Think about it, why do we get cloud to ground lightning? Because a charge jumps between a buildup of negative energy in the lower troposphere and the positively charged ground. conversely you get lightning within the cloud between the negatively charged lower troposphere and the positively charged stratosphere. There are differences in charge like this all through the layers of the atmosphere right out into space, imagine what would happen if you ran wires between these differentials and the ground.

[@Me__Myself__and__I]

@@timbert4672 I'm sure the expert scientists and researchers who have spent time on this including at NASA have taken that into account. Most likely nothing would happen. Lightning occurs because a massive differential is allowed to build up over time. Running a wire up there so that it could continuously discharge and equalize would prevent the differential from building up. People do this every day in fact, this is why people ground themselves when working on sensitive electronics. Same principal.

[@timbert4672]

If you ran a what is basically a giant metal pole between these charge differentials, you’d short circuit the entire planet. What the result would be I don’t know, but you know how powerful lightning is, hence me mentioning it. Perhaps steps could be taken to prevent it though, for example, encasing the structure in a non-conductive material. This is another example of why a moon based orbital tether would be easier, it wouldn’t have this issue.

[@DudeSqaudYT123]

Thanks!

[@Mystikan]

The Mid-Atlantic Ridge is a bigger problem than you've described. It's a spreading rift, widening the Atlantic Ocean by 2-5 cm (1-2 inches) per year. This will rapidly "stretch" the section of tunnel that crosses the rift zone. This would entail some kind of telescoping mechanism that would allow that part of the tunnel to expand with the rift, and making something like this that can withstand the ocean pressure would be a tremendous feat of engineering in itself.

[@Spermwhales93]

I feel like the transatlantic tunnel could work if it went from northern Scotland to north eastern Canada via the Faroe Islands, Iceland and Greenland. It would save a lot of money because less actual tunnel would need to be constructed, the tunnel wouldn't have to be as deep in plenty of areas as the sea floor would be a lot higher and it could service more places than just London and New York, making it much more economically viable. The whole g-force acceleration problem could also be mitigated by making it fully automated and for cargo only, so no human passengers would be on any part of the train at any time. I was thinking a route that goes Thurso (UK - mainland) -> Kirkwall (UK - Orkney Islands) -> Lerwick (UK - Shetland Islands) -> Torshavn (Faroe Islands) -> Rekjavik (Iceland) -> Nuuk (Greenland) -> Somewhere on Baffin Island in Nunavut in Canada, and then maybe continuing on towards Montreal or Ottawa, with freight terminals at each location where cargo could be offloaded for local transportation. It would be a longer journey overall for any freight that would use it and potentially would require construction work in ecologically sensitive areas, but it could mean that we wouldn't have to do as much air freight and it would help make transatlantic freight transport a little more environmentally sustainable as you could run the entire system using renewable power. You could also potentially also build another one of these tunnels branching off from Lerwick to around where Bergen is in Norway, creating a link through the North Sea to the transatlantic system.

[@Byplasse]

Another crazy project ......an engineer proposed to dam between James Bay and Hudson Bay in Northern Canada. Half of Ontario's, and Quebec, fresh water flows into James Bay so the salt water will eventually get replaced by fresh water.

I think a train to New York from London is not out of the question, because by adding only 800km, you can instead go via Glasgow/Edinburgh, Reykjavik, Nuuk and Montreal/Quebec, only requiring 3600km of underwater tracks instead of 5500km, making construction IMO significantly easier (as I believe the underwater sections will be much harder to construct), adding in more destinations making it more financially viable by utilising other country's GDPs to finance it and to make it more appealing to travellers who may not want to make the whole journey. It also means it can be operational before being fully constructed, eg. using a London to Reykjavik route while the North American portion is being built, which couldn't be done using a straight line across the Atlantic, helping it finance itself. Adding stops would significantly increase the journey time but using the other countries helps make it more viable

A tunnel between New York and London seems really inefficient. Theoretically I would have a train connecting New York and Toronto to Halifax, then going up Nova Scotia with a tunnel connecting to Newfoundland (presumably stopping at Saint Johns), then seeing about doing a tunnel into Western Ireland (Galway for example) then along the mainland to Dublin, across (or under) the Irish sea to Liverpool, then maybe hitting Manchester, Birmingham, Oxford, and finally London. It would be significantly slower but dramatically cheaper if we went to the easternmost point of North America. It could also serve more areas this way, although I'm not sure how fond of this idea the Irish may be. I don't know if the topography would be good for Maglev with this idea either or the exact latitude of Newfoundland compared to the British Isles (although i believe they're similar), but to me, it just makes the most sense to reduce the underwater time

Damming the Red Sea… would completely fuck up the Suez Canal 😂

350 years to start energy production on the dame should be a deal breaker. the infrastructure will rot before then

the wandering earth 2 space elevator is more realistic

"Freedom Ship" seems most plausible. A mega giant cruise ship with tax loopholes, and unrestricted regulations for a corporation to set up as a domicile. Then, you add various attractions for visitors. It could become financially sound. As for aircraft noise on the top deck, maybe this can be engineered to make it quiet. Trying to sail without flying a flag of a nation and have maritime insurance is a HUGE challenge. Flying a nation flag could kill corporate domicile laws for tax and regulation savings. On paper and regulations makes it a non-starter, not the tech. The other projects have tech issues making them non-starters. Maybe Bitcoiners need to look into creating an Anarcho-Capital state on the Freedom Ship.

How about the N. Sea dam, variously between Scotland and Norway or England and Holland etc, as well as a dam between England and France (ie to isolate the N. Sea from the Altantic Ocean). This would be cheaper than trying to prevent flooding in London, the East coast of England in general and floods on the German, Dutch and French coasts, with the rise in sea level which will occur over the next 100 years. In addition the island being built by Denmark, for a wind farm, and the existing wind farms in the N. Sea shows that there is a market for draining parts of the "Dogger Land" that would be recovered. Far more realistic than most mega projects. It also makes a second crossing of the Channel redundant. It would also solve the UK problem for another London airport.

What if instead of tunneling the entire width of the atlantic, you break it up into sections with a network of tunnels from London to The North of Scotland to The Faroes to Iceland to Greenland to North Canada down to New York. thus connecting Europe to North America. Seems like it would be further, but when you factor in the curvature of the earth. Similar to the flight paths, most planes take

You forgot the craziest project of them all, Atlantropa, the project to drain the Mediterranean sea.

[@BIGJATPSU]

RIGHT!!

He already made a video about it kzbin.info/www/bejne/b5zHZpmbodSkibcsi=OLzcR7X80pCUO7qe

How would a transatlantic tunnel deal with the fact that the Atlantic is getting wider all the time?

Halo has space elevatorS and they look so cool.... that's also 500yrs in the future.
