  2. On your next video you should highlight the failure test of carbon fibre and glass fibre hulls that Carl Ross posted 10 years ago. He posted 2 videos titled Collapse of Composite Submarine Pressure Hulls Collapse of Carbon & Glass Fibre Tubes under External Hydrostatic Pressure. I have no idea who Carl Ross is (or was) but there's 2 things to note about those videos. 1) How sudden the failure is. If you look at how titanium fails its much like any other metal there's deformation eventually followed by failure. I am an engineer (aerospace) but did my first year in mechanical and we did that stuff in the lab. Most of the failure videos of things being crushed or bent in a hydraulic press show that but they also often show the sudden failure of carbon fibre composite materials. So you and other are most likely right the people in Titan probable had no warning it was all about to fail other than hearing a lot of cracking. 2) the Carl Ross videos show very little damage to the Carbon fibre tube other than what looks like a crack down the side. What people need to understand is that it was done in a small pressure test rig NOT the open ocean so there was very little water to keep applying pressure once the tube failed. I have done work in the petro-chem industry and other places where they pressure test pipes with water. If something does let go during a hydrostatic test there's no explosion of water because its incompressible. That test cell Carl Ross used has very little water in it so there's not a lot of volume to rush into the test model and do lots of damage. It just had enough water to break the cylinder.

  13.  @wgowshipping  AUSTRALIAN HERE MATE: When you get to Australia let me know I owe you at least the first beer and it will be a real beer. FYI - I'm an aerospace engineer who works in industrial control systems and automation. I have spent most of the last 20 years in our mining industry because I met one of the last 2 guys to walk on the moon and he said we'd be most likely going back to the moon for mining. There's a couple of very rare and potentially very valuable substances on the moon. At its most basic its a logistics problem of how do we get people & supplies to the moon and people & product back. Back in 2010/11 when working on a Alumina smelter project the manager I worked for one day told me that in the future LOGISTICS would be the most important facet of world trade. I didn't quite understand it at the time, but have come to understand its insanely important to so many things in our lives. You might not realise it but the Apollo Missions to the moon were a success because Buzz Aldrin and a couple of other guys solved the LOGISTICS problem of getting back. Getting there was one thing getting back was another. Go watch the video titled "I Was SCARED To Say This To NASA... (But I said it anyway) - Smarter Every Day 293" by Destin who's an aerospace engineer and listen to what he says about the new Artemis mission. Its a logistics issue with some serious flaws. These days my primary interest is in Energy Economics because the main stream economists have utterly screwed the pooch with all of our Energy Sectors which are all about logistics. It doesn't matter if we talk electricity, gas or oil they all involve moving stuff from one place to where its needed. I bet you never thought of the power grid as a logistics system BUT IT IS. It moves electrical power from where its generated to where its used and that's a logistics system. I'm scheduled to be on the Steve keen & Friends Podcast this week to discuss Engineering and Economics and there's a better than fair chance you're getting a plug because like engineering, economists don't really get logistics and that's a major issue.

  19. AUSTRALIAN HERE: I am all in favor of Australia getting nuclear powered subs that are compatible with American systems because America is our principle security partner. HOWEVER I MAINTAIN that the AUKUS program as is is currently being done is an UNMITIGATED DISASTER for Australia. FIRST - Its insanely expensive and we are not guaranteed the delivery of 1 submarine. Former Prime Minister Malcolm Turnbull who has been a very successful business man during hos life has been scathing in his critique of the program. MOST of the costing is still being kept secret from the Australian people. SECOND - Despite the Virginia-class being a fantastic submarine and I have no qualms that it is the leading technology. *IT IS FUNDAMENTALLY THE WRONG SUBMARINE for Australia. The Collins-class we currently have 6 of have a basic crew of 60. We have never been able to fully deploy all 6 because of crew shortages. The best we have had is 4. Despite having over 800 qualified submariners we only have an effective submariner corps of 240. The Virginia with a crew of 139 is simply more than we are capable of using. We just do not have enough submariners in our society to use the Virginia. Those are just the basics after that it gets more and more technical. Its a great sub for a nation of 340million people but its a bad sub for a nation of 28million people. AND Mark, despite his background, should not be praising anything about either of the LCS class boats as they have both been well documented as failures. They are the first ships in modern history where ships are being retired in a class while the class is still under construction.

  33. ENGINEER HERE: Sal it was the Americans who blew the Nordstream Pipeline. People like Larry Wilkerson and others with military backgrounds have pointed out the skill sets required. Once you realise what sort of pipe Nordstream was made from and what it would take to split open 50m sections you can discount the idea it was 4 Ukrainians on a rented fishing boat. I have worked in the oil & gas industry and can tell you that pipelines like Nordstream are NOT simply a pipe that sits on the bottom. They are coated in several inches of reinforced concrete. The concrete does 2 things. 1) It helps the pipe sink to the bottom and stay in place. If you just had a sealed pipe it would float the same way steel ships and submarines float when they pump all the water out of the ballast tanks with air. 2) It helps protect the pipe from the marine environment. There's several video's here on YouTube showing the construction of Nordstream and you can see this layer. They also talk about coating the welded area where they join sections but that only applies to the welded area. So to rip open 50m sections of that type of pipe requires specialised demolition explosives capable of first cutting through several inches of reinforced concrete and then cutting through several inched of steel pipe. Then it requires a specialised team who can do that in the darkness and cold of the Baltic at depths of 150feet or more. Larry Wilkerson (who was Colin Powell's 2IC at the State Department) in one of his interviews for the Analysis News channel here on YT explained how the only team in the World with that skill set is one of the American Seal teams that trains for underwater demolition. He said maybe the Brits could try it but they would need American assistance. My bet is the charge on the 4th pipe (which did not get blown up) failed for some unknown reason and the Swedes found it when they investigated. It should be noted that Sweden has NEVER released details of what they found.
