Back in the 1990s during my summer vacations from studying I was working at a local shipyard in Finland where they made LNG tankers. It was a great experience to visit the inside of the gas tanks and to see how the seams of the tanks were welded together. Very nice memories from times when the world was a bit different place and when the Finnish shipbuilding industry was still at the very top in the world.

It's really a shame that some people are in a situation where they have to rely on tv to supply that basic info what's even more, a shame is that source of knowledge, making inaccurate statements like nitrogen being inert.

[@DylRicho]

@@MrDJAK777 Molecular nitrogen is inert.

[@MrDJAK777]

@@DylRicho no it's really not, edit for this use it may pass as "inert" but even then that's not why it works here it's just displacing oxygen making combustion of natural gas impossible. I can go do a reaction involving n2 right now it is not truly inert hell not even the Nobel gases are truly inert.

[@Valsorayu]

​@@MrDJAK777 Inert is a relative measure, in chemistry at least. Diatomic Nitrogen is classified as an inert gas under standard conditions, mainly due to a triple bond and it requiring alkali metals to react. Fluorine reacts with some of the Noble gases (outside of standard conditions), they are still classified as inert. Don't be a twat.

It was in the 70s when I watched the show Connections with Jack Burke. It was very similar to this show's format. Even with the new name Engineering Connections with Richard Hammond I still find it immensely entertaining and educational, even at my current age. The brave little mouse makes science interesting.

[@greigshearer5614]

one of my favorite examples is Cavitation on a submarine. due to the depth the blades boil the water making the cavitation noises as the bubbles burst, giving away their position. it was fixed by making it 5 blades and turning the props slower. amazing!!!!!!

[@justlucky8254]

While I was working as a machinist at a navy shipyard, I was loaned out to the propellor shop for almost a year when they were shorthanded.

The fact that one of the adds for this is the full length video of "obey" by BMTH and Youngblud is well worth a like

[@kennethbutler1343]

Love these vids, but at around 10:20 he compares jet fuel to natural gas for volatility. Military grade jet fuel is basically kerosene, which is so non-volatile, if you threw a match into a bucket of it, the match would extinguish itself. Yes, when it burns there's a LOT of energy in it (Saturn V rocket's 1st stage used kerosene and liquid oxygen after all) but it needs a pretty good ignition source. Also, 14:50...nitrogen isn't a poisonous gas. He even says it's inert several times...it can't be both. The only danger in a room full of it is suffocation. I'm surprised there's two such glaring mistakes as this series is pretty good otherwise.

[@13minutestomidnight]

Doesn't he make the comparison to jet fuel specifically because of the way mid-air re-fuelling planes prevent fire occurring in the re-fuelling connection/nozzle thing (yeah, I've forgotten the name)? By using nitrogen gas to displace the oxygen (thus preventing a spark from igniting fuel)? I'm pretty sure the suffocation issue with nitrogen gas is what he's referring to (the context kinda hints at that), but "poisonous" is definitely the wrong word. Like all other inert gases (well, in a low/no oxygen environment), it's not toxic, but deadly exactly because the body absorbs it instead of necessary oxygen. For some reason people seem to confuse these terms a lot (probably not a good idea)

3:55 that’s where Ryan Johnson -the writer and director of Star Wars Episode VIII got the idea for that scene with Ray in the Dark Side Cave. Richard Hammond starring in Star Wars confirmed

[@nick4819]

No it wasn't. It was the pressure cap on top that ruptured. Audio is replaced on almost all tv productions to make it dramatic. That boom is not what this sounded like.

[@ginge5253]

Also as an engineer I'd like to have know what grade of S/S steel is used as I've worked with 304, 308 and 316 plus a cheaper type that I forgot the code for, which seems to have the look of stainless steel but has a higher iron content (no clue why) and is used in high temperature applications ie power stations but is nearly the identical cost of mild steel but will still rust at a slightly slower rate than say cr4 or typical hot rolled mild steel.

[@justlucky8254]

There's so many options. 303, 316L, 17-4PH, etc. It's hard to explain to some people that some stainless is magnetic. Some is great for cold forming, some will just crack, some have excellent weldability and some you'd never want to weld. I'm a machinist so I'm interested in different types of metals. My favorite to work with is explosion bonded materials. Examples are aluminum that's bonded (basically welded with explosives) to stainless, or titanium bonded to stainless, copper bonded to aluminum, etc. I worked for a company that made ultra high vacuum chambers for places like NASA, CERN, Los Alamos National Labs, JPL, SpaceX, etc. The chambers have many flanges on them and aluminum doesn't work well for sealing flanges together therefore other companies would make the entire component, and they're huge, out of stainless. That makes them heavy and expensive, difficult to machine, etc. We built ours out of aluminum because we had flanges that were aluminum on one side to weld to the chamber, and stainless on the other side in order to have a seal good enough to be under such high vacuum.

22:30 It is not just chrome that needs to be added to steel for it to be tough at low temperature, but also nickel which promotes an austenitic crystal structure. With only chrome it would be martensitic or ferritic and brittle at low temperature. I bet that tube is 316 stainless which is austenitic. Only austenitic stainless is tough at low temperature, also very corrosion resistant. You can tell if stainless is austenitic by putting a magnet against it, austenitic stainless is not magnetic despite being mostly iron.

[@SkashTheKitsune]

if it kills you, then it's toxic... in small amounts it just passes right through you, really... your urine is mostly nitrogen and what you breathe out is mostly nitrogen

[@DomWPC]

nitrogen can't kill you directly, however if it replaces the oxygen in the air then you can't breath it and you'll suffocate

[@elias_xp95]

Everything is toxic. Literally. There is a toxicity scale for every chemical in existence. Some things are toxic but perfectly harmless. Others are toxic and harmful.

[@elias_xp95]

Just for reference this is the WHO grading scale. As you can see, something with grade 0 toxicity is essentially harmless to humans. www.oncoprof.net/Generale2000/g09_Chimiotherapie/Complements/g09-gb_comp01.html

[@57thorns]

Nitrogen is non-toxic, at least under normal pressures and temperatures, but can prevent an asphyxiation hazard by replacing oxygen. Not everything that kills you is toxic. After all, almost 80% of the air we breathe is nitrogen.

I thought they ran on diesil! That's awesome that they're eco friendly :)

[@elonmusk8711]

The steam is just the working fluid. Heat to boil water and produce high pressure steam still has to be generated by burning a fuel - and that fuel is usually *fuel oil,* also known as 'heavy oil' or 'marine fuel'. Fuel oil actually burns way *dirtier* than modern low sulphur diesel fuel. I don't know what kind of magic pixie dust you think they have that would allow them to produce high pressure steam without a heat source. Ships like this are literally some of the least 'eco friendly' things on the planet. They are however, necessary.

[@dave1986R]

@@zuilok >> Atomic bombs are mainly used as a measure for energy, because that's what most people are familiar enough with to understand the immense forces behind and to know that the release of said forces are extremely dangerous.

4:30.. Temp is NOT -160f inside...if it was then propane tanks on household grills would be iced and frost covered when both being used and not used...compressed liquids must change state to a gas to get that cold...compressing gas to liquid is done for a few reasons and most obvious is you can carry much more liquefied gas than gas vapor only...puting under pressure is much safer as liquids do not burn(they do have a flash point but that's another story...tanks inside will be the same temp as its surroundings and walls of the tank...pressure only changes the temp to change state...it increases the temp the liquid turns to vapor...in the atmosphere is when liquid gas turns to vapor at his -160f...vapor itself is not cold...its the changing of state from liquid to gas responsible for the cold as compressed gasses absorb a lot of heat when turned to vapor...its exactly how your home air conditioner works...it took energy to compress the gas to liquid and it releases that energy when the liquid turns back to gas
