- pmiller2 6y agoYeaaaah, like that wouldn't have any unintended consequences. Meanwhile, I find this more interesting: https://en.wikipedia.org/wiki/U.S._Army_Corps_of_Engineers_Bay_Model https://en.wikipedia.org/wiki/U.S._Army_Corps_of_Engineers_B... The Army Corps of Engineers literally built a scale model of the San Francisco Bay Area, and they used it to figure out that damming the SF Bay was a very, very bad idea: https://www.youtube.com/watch?v=i70wkxmumAw https://www.youtube.com/watch?v=i70wkxmumAw

[0] In the absence of accurate computation modeling (either hardware or physics models) in the 1940s-70s, it's a pretty ingenious way to simulate complex hydraulic systems. And as for Atlantropa, think about it in these terms: (a) a large, funded public-works program in Europe, just as the Nazi Party was gaining support and before the Spanish Civil War, (b) substantial amount of cheap, carbon-free energy for Europe and North Africa by now, & (c) a pan-European effort ~50 years before most EU structures. You'd have a hard time convincing me that would have been doomed to turn out worse than actual history.

- pmiller2 6y agoI didn't know about that one. Are there other scale models of large, physical hydrodynamic systems out there?
- ethbr0 6y agoI'm not as familiar with international flood mitigation projects, but I'd expect any built before ~1990(?) had something similar, albeit in varied scale. It's interesting that the Mississippi model's scale was specifically chosen to minimize unrealistic effects of surface tension, that might have dominated at a smaller scale. (But it was the 1940s, and I'm sure we know more about surface tension and hydrodynamics now)
- billfruit 6y agoWhat software system would be used to do the same modelling and study if it had to be done today?
- potiuper 6y agoThe Reber plan <https://en.wikipedia.org/wiki/Reber_Plan https://en.wikipedia.org/wiki/Reber_Plan> did not intend to "dam the [entire] SF Bay". Off topic, is there a reason why comments do not support HTML anchor elements?
- wadkar 6y agoComments do not support HTML. I would imagine Too many issues with parsing, injection/security etc.
- tokai 6y agoIt would surely have been a disaster on many levels. But imagine all the archaeological sites that could be uncovered!

- 1cvmask 6y agoThe German “pacifist” projects’ ideals which of course excludes Africans: The utopian goal was to solve all the major problems of European civilisation by the creation of a new continent, "Atlantropa", consisting of Europe and Africa, to be inhabited by Europeans. Sörgel was convinced that to remain competitive with the Americas and an emerging Oriental "Pan-Asia", Europe must become self-sufficient, which meant possessing territories in all climate zones. Asia would forever remain a mystery to Europeans, and the British would not be able to maintain their global empire in the long run and so a common European effort to colonise Africa was necessary. It is like the British “pacifist” Prime Minister David Lloyd George who was for European disarmament except for blacks: “We insisted on reserving the right to bomb niggers." So David Lloyd George explained the British government's demand at the 1932 World Disarmament Conference to keep the right to bomb for "police purposes in outlying places". Airpower had shown its value in spreading what Winston Churchill, when defending in 1919 the use of poison gas against "uncivilised tribes", had called "a lively terror". https://www.theguardian.com/books/2011/dec/07/britains-empire-richard-gott-review https://www.theguardian.com/books/2011/dec/07/britains-empir...
- awiesenhofer 6y agoIt will be very interesting to see how Norways coastal highway project turns out.[1] They plan to bridge and tunnel some massive fjords, some >1km deep, similar to the Straight of Gibraltar (~900m max depth). Plans are in the works for floating pontoon bridges as well as submerged tunnels. Depending on which solutions they choose and what their findings will be, if it works out when built an actual road/train connection between the continents could become - at least technically - feasable.

- lazyant 6y agoOr, Egypt could build a pipe between the Mediterranean and the Qattara Depression (~ 100 Km), which is below sea level, so you'd get water in the desert and power as well. (Half jokingly, this probably won't work?)
