YOU DON'T CAST KNIVES OR SWORDS OR ANY TOOLS LIKE THAT

tools of this type are forged! if you cast them, you end up with something super brittle and hardly suitable for its intended purpose of chopping and slashing and hitting! even back in ancient rome, when a good sword was some of the highest technology on the planet, they would only use casting for cheap disposable things like the bronze heads on the spears you'd give your slaves!

Casting bronze doesn't make it brittle it does the opposite, makes it too soft to be a weapon. You need to whack it with a hammer a bunch to work-harden it so it will take an edge.

(Also you don't give bronze to your slaves, that poo poo's expensive.)

Now iron, yes. Cast iron is brittle and useless for weapons or armour.

I think that was the point. They're churning out poo poo swords the same way they're churning out poo poo orcs. Just get enough of them out there, and if they can get one good whack in and kill a human, job done. They're only expecting the swords, and the orcs, to last minutes in a fight.

in ancient rome cast bronze made better swords than iron; iron and the iron age are only a thing because there's a lot more iron laying around and it can be forged without complex metallurgy as soon as you figure out how to get a fire hot enough. this enabled you to quickly and inexpensively arm 1000 peasants to stand in front of your few dozen noble bros with your heirloom bronze weapons, even though their early iron weapons were dull, rusty and brittle in comparison.

Re the littoral combat ship, congress wanted it to cost less so they looked at all the features and said “cut this, cut this, cut this” and one of the things they cut to reduce cost was the galvanic corrosion protection system. For reference, the lcs is made of steel and aluminium, and when you have two different metals in contact with eachother in an electrolyte (such as sea water) you get a voltage differential between the two that causes oxidation (and hence rusting) exceedingly quickly. As such, by removing the galvanic corrosion system to save 10 grands with of copper wire and a transformer, they instead made the hull rust through in barely a year. Designing things by committee strikes again!

lol active galvanic corrosion systems aren't even needed

just a couple hundred pounds of anodes bolted to the hull

After the posts about signaling in the UK I am not sure this genius or terrifying.

https://twitter.com/JamesMelville/status/1080761345157541888

My take on this is that the reasons it looks scary are the engineering aspects of it. The layout looks pretty standard.

It's a flyover. That inherently reduces risk. The lines down the middle appear to go straight on, and the ones on the outside go eventually off to the left. So it's a left hand turn, and from the other direction a right hand merge.

If you had to design a road layout with a left hand turn and two way traffic you could just slap the roads together. But that means to change direction you always have to cross lanes of traffic. So you've got conflict points. A manageable risk at low speed and with low traffic numbers. But if you had high speeds and high traffic numbers the risks are too great. You don't get many straight junctions on motorways here. I don't know how it is in the us on freeways.

That's why the lines here cross over the top. Otherwise stuff going straight on from our perspective (on the left hand track) would have to cross over the lines of the stuff coming from the left. In the setup in this video there are fewer conflicting moves.

What is interesting to me is there are no lineside signals, so it's either in cab signalling or automatic train operation. Judging by the speed the train is approaching the junction when the points aren't set I'm guessing it's ATO of some description.
