Testing the WWI concrete ships and WWII concrete barges
- jimnotgym 5mo agoInterestingly concrete yachts are a thing. Ferro-cement is the term, but it is just reinforced concrete. You can buy very large yachts for small amounts of money with yachts made this way in the 70s. Insurance can be tricky for no really good reason
- ofalkaed 5mo ago>Insurance can be tricky for no really good reason It is very expensive to prove a ferro hull to be sound, which is a requirement for getting insurance.
- davidjade 5mo agoExcept the steel armature inside can turn to hidden rust and if you do something and crack the ferro hull they can be a total loss. A lot were home built so finding a quality build is another issue. There’s a reason insurance won’t touch them.
- ninalanyon 5mo agoWas this created by AI and not proofread or created by a human and not proofread? The paragraph relating to the Musgraves taking over a factory is repeated and it reads rather oddly. Anyway, regardless of that nitpick, it was an interesting read.
- jml7c5 5mo agoProbably a copy-paste mistake while quoting the source. If anything, it makes me less inclined to believe it's AI generated.
- warumdarum 5mo agoYou could do that today for cargodrone boats sintering or epoxy glueing beachsand?
- sandworm101 5mo agoOr melt the sand and form it into long strips, fibers, then glue the fibers together in some sort of glass-fiber-epoxy type material. Get the patent done quick because that sounds viable imho.
- margalabargala 5mo agoGlass fiber? Ridiculous, that'll never work.
- UncleSlacky 5mo agoReminds me of "pykrete" which was also a potential construction material for ships (notably aircraft carriers) proposed during WWII: https://en.wikipedia.org/wiki/Pykrete https://en.wikipedia.org/wiki/Pykrete
- robotnikman 5mo agoNotably Project Habakkuk, which if built would have been the largest ship ever created. https://en.wikipedia.org/wiki/Project_Habakkuk https://en.wikipedia.org/wiki/Project_Habakkuk
- trhway 5mo agoback then it were large ships. Today the issue is building large Starships. How many would we need to move several millions people and various equipment to Mars. May be not ice - though ice should work if building in space (or on the Moon). And ice can be oxidizer if aluminum is used as fuel, so you just burn large part of your ship too. For building on Earth - something cheap and easy to shape. Say 3D sinter-printering from sand.
- 5555624 5mo agoASCE (American Society opf Civil Engineering) has an annual Concrete Canoe Competition. (https://www.asce.org/communities/student-members/conferences/asce-concrete-canoe-competition https://www.asce.org/communities/student-members/conferences...)
- vonnik 5mo agoOne of these capsized off the beach at Capitola and now serves as a de facto bird sanctuary. https://www.mercurynews.com/2019/05/29/ss-palo-alto-reaches-a-century-a-little-worse-for-wear/ https://www.mercurynews.com/2019/05/29/ss-palo-alto-reaches-... Before it capsized and sank, it served as a dance hall at the end of a pier.
