Maybe in an alternate, more peaceful world, Russia would be happily selling icebreakers to the US for profit?
Frankly, Russia as a Chinese suzerainty might be one of the more productive alignments for the global economy, even if it isn’t great for America.
Although it is usually ignored, geography is fundamental to understanding why nations act the way they do.
Say Russia achieves is "geographic necessity" of conquering Ukraine (which I very much wish doesn't happen). What's beyond there? Romania is a mix of plains and mountains - so what, Russia gets to invade there? Poland is mostly flat and with few major obstacles (Vistula running south-north is probably the only major one - and a very topical one...). So then what - extend the "buffer zone" into Germany? And... Finland? And I mean, you can't trust these warmongering Swedes and Norwegian - remember the Vikings? Better pacify these guys too before it's too late.
It's not a logic anyone outside of Russia wants to entertain.
This is Russia's argument, but it is nonsense. Nobody would attack any Russian border, western or otherwise, because Russia has thousands of nuclear weapons. It's as simple as that.
The US is something of an outlier. Most countries maintain much smaller militaries. They have them on hand for a variety of purposes: disasters, foreign peacekeeping, border patrol, and keeping their hand in Just In Case.
NATO countries, for example, are supposed to keep militaries so that Russia doesn't get any ideas. Say, Wagner troops meander across the border into Poland. Russia clutches its pearls and says, "Oh, no, don't end the entire world by nuking us even though it's obvious that we ordered it." So troops would get sent... which is why it never actually happens.
How much military you need to achieve that is up for debate. The US often claims that other NATO countries need more, and that the European countries are relying on America to provide most of that deterrent. But the US is almost certainly providing way, way, way more deterrent than is needed -- more about national preening than serious consideration of needs.
Just in case of what? Nukes are the perfect defense and the only one you need you said it yourself. You think 4% of the GDP is wasted.
Nukes get MAD real fast. If their only weapon is a nuke, their bluff could easily be called.
Very few countries spend 4% of GDP on the military, and most of them are at war. Not even the US, which comes in at 3.5%. NATO countries are supposed to spend (IIRC) 2%, but most don't.
It's a 2% that they might like to have back, but militaries are pretty good make-work programs. Even Japan, whose constitution prevents it from having a military, still spends 1% on its military.
Do you have any scenario of how that would happen, so that Russia's invasion of Ukraine makes any sense as a preemptive move?
I mean goodness, can we just admire a cool boat for a second?
What? With this  comment? Look at the time stamps. (Do we know each other?)
> Don't you have anything at all nice to say about them?
About the current Russian state? No. It’s pathetic and broken, and I don’t see a way to fix it other than devolving it—functionally, not legally—to China.
About Russia as a culture, people and nation? Of course. Russian literature from the classics (Turgenev) to mid-century (Bulgakov) and modern, together with Soviet films, are among my favourite genres. I love the food. I adore the operas and music. And Russians’ sense of wit and humour is among the sharpest and funniest in the world. As a species also we’re eternally in the Soviet Union’s debt for their aerospace and medical advances, to say nothing of dealing the death blow to the Nazis at Leningrad.
Much of my bitterness towards Moscow stems from knowledge of the potential of Russia’s people that is being squandered, delayed or permanently destroyed, in service of delusions.
Totally misread you ;)
Why the USSR did not become a major industrial exporter has been the subject of some good historical studies. It's been a while, so I don't have any good references at hand, but I recall that the main problem was Soviet management policies. Companies had a very hard time implementing quality control, and the government was also reluctant to close obsolete plants, because their primary goal was to maintain full employment.
Also declining population and worsening education.
There is a statistically significant correlation between the level of corruption and economic growth:
Putin has dismantled most of the check and balances in the system. Nobody would invest in that country. Check Bill Browder's story on how they raided the Hermitage fund.
And with this useless war going on they're forced to buy arms from DPRK.
Claim without evidence. Let’s throw in a bit of whataboutism- have you seen how improbably good pelosi’s stock market trades are? Almost like she’s insider trading.
> Also declining population and worsening education.
Population seems to be more or less in line with the rest of the world, and likely better once you factor for immigration.
“In 2014 the Pearson/Economist Intelligence Unit rated Russia's education as the 8th-best in Europe and the 13th-best in the world”
“In 2016 the US company Bloomberg rated Russia's higher education as the third-best in the world”
I mean really. I get that we all have biases, but lying about such easily verifiable things is pathetic, even for the average anti-Russian propaganda shill.
Corruption data with sources:
About demographics check these:
Let's not cite "Bloomberg" as a good data source for this. It's not good enough.
The “demographic crisis” appears to be on par with, if not better than, what the vast majority of Asian and European countries are experiencing.
And are you seriously quoting “perceived corruption”?
That’s a subjective measure. It’s literally in the title.
Could you at least try instead of throwing random links that you probably haven’t even reviewed yourself? Because this is pathetic. I expect more rigorous research and effort from an HN reply.
Personally from hiring people and from my brothers 2 businesses there is a stagnation too. The government talks about "reforming" the universities to break with Bologna system with internationally recognized degrees - this won't help either. Additionally along with the reform and with all the sanctions it'll be harder to go to foreign universities for students.
And don't forget all the "arrests" of prominent scientists:
Population is declining and the war won't help with that either. It doesn't matter than in Japan it's worse, we're talking the number of people in active economic age going down. This is not good in the long term, who would work and pay pensions? Oil is a finite resource.
About the corruption, I can tell you many personal stories (tax authorities & fire department are one of the worst ones and if you try to build something without bribes it's impossible to get the paperwork done ), but this would be hearsay, not data. There are 2 global indices and both suffer from subjectivity. You can check the trends for direct foreign investments and capital outflows from Russia, especially after 2015.
Russian ministers live like billionaires and fly their dogs to Europe in private jets (check the story of Shuvalov's dogs flights). I'm not aware of such gimmicks in the "morally bankrupt" western countries. You're correct that it's subjective, but it's subjectively better in Sweden and Germany than in Russia or Ukraine. If you can't provide a better metric your argument is even more subjective, because it's not aggregated from many people over the years (the trend should be correct even if the values are not).
So please provide links and data, not your "expectations".
And do you live in Russia and have personal experience as I do to have a better subjective perspective?
Actually things started going south for the Russian economy in 2010-2014 when both US oil companies and Saudi Arabia started pumping out oil as no tomorrow.
The last batch of such manufacturing apprentices went through in the mid-eighties. They're just about all gone from the workplace.
I know it can build military vessels, but at horribly slow pace. Australia will get their nuclear submarines some time in 2040. I can not imagine building civilian nuclear ice breakers in US.
The article was about getting new ice breakers for the Coast Guard, a branch of the US military.
But Korea is operating at a much, much grander scale and scope. Like having a chain of 7 respectable burger shops vs. McDonalds.
I don't understand. Aren't modern military ships armoured anymore?
But it's important to note that before the Iowas were given their final retirements into museum ships the Navy made sure to basically document everything they could about firing large caliber guns. Because when they initially pulled them out of mothballs in the 1980s they were woefully inaccurate, but by the time they were decommissioned for the final time they could hit a proverbial fly on a flag pole (allegedly).
The other part of it was that the Soviet Union didn't really have a surface fleet to really speak of. They invested heavily in submarines, so consequently the US Navy focused heavily on ASW. So... nobody really knows how 16" of modern armor would fair against modern weapons, it's literally never been tried. Whereas you can find pictures from way back when they were testing guns, of how various shells fared against various thicknesses and types of armor.
Long story short: We've forgotten most of what we knew about surface warfare, and we're starting to forget what we knew about shipbuilding and design. The US has outsourced all it's naval architecture and shipbuilding so long that the necessary skills are either all retired or lost.
It was Mitsubishi Ki0167, according to Ryan Szimanski the curator of the Battleship New Jersey, in this video.
This marked the effective end of the concept of armor thick enough that it couldn't be breached, and the Battleship.
No, no amount of armoring is useful against modern weaponry, but it does increase the "m", thus lowering the "a" you get from your engine's "F".
Wire up a cheap boat with explosives and it can sink an expensive naval vessel. The Ukrainians are using this to massively great effect right now against the Russians.
What if instead of building one new aircraft carrier, you build an autonomous submersible capable of launching drones with variable payloads?
Or instead of a destroyer, build a drone ship that can launch missiles?
Or an entirely new class of ship that simply swarms enemy defenses and is laden with explosives? Mass-produced autonomous jet skis with explosive payloads. But faster.
This has been pretty obvious since the Millennium Challenge 21 years ago, when they just called them suicide attacks. Nobody seems to have cared then and not much has changed.
I think the issue is pretty tightly limited to boats/sea drones, though. If you're even a few feet under the surface then sonar can see you. If you're a few feet above the surface then radar gets you. Both options die a mile away.
I also think Russia is probably not very representative of the overall threat, too. I don't think their navy is running particularly better than their army. I don't know that other navies can do much besides trying to spot ships and blow them up with guns (do top-attack missiles work?) but whether or not they're good at it they'll definitely be much better than Russia. Until there's some sign that countries are actually investing in sea drones I don't think anything will be done, and I wouldn't be surprised if some kind of small top-attack rocket makes it a non-issue.
> autonomous submersible
autonomous and submersible don't go very well together. Radio contact underwater is terrible. It's not like drones fly themselves; we haven't figure out the whole autonomous thing.
> capable of launching drones with variable payloads?
Landing a plane on a ship is actually really hard and requires constant maintenance, even for VTOL. Even for helicopters. Smaller the ship, harder it is to land.
> build a drone ship that can launch missiles?
But like, why? Why not have people on it? Ships are not big because of the people on it. People can treat casualties, repel boarding, land on the ground etc. Ships are also constantly being maintained and repaired. Waves and salt are a real bitch.
If you make a ship without people it'll cost almost the same, be almost the same size, be very hard to repair and be much less capable.
Simply looking at costs and complexity "on paper" from an engineering / accounting perspective doesn't really capture all the differences between humans and machines, especially considering civilian morale.
The US military lost <2.5k in Afghanistan over two decades, and that generated enough war weariness for us to quit.
The current American public and political system simply isn't willing to tolerate large numbers of casualties. So it makes a whole lot of sense to take people out of the equation.
Obviously not combat vehicles but it’s not hard to imagine such a thing being reframed in a similar way.
Does anyone know of any good sources on this?
Like most trade workers, the worker owns the tools that they use on the job. When they sell their tools, they leave the trade.
I don't think there have been any good studies or histories written about the decline in tradeskilled labor.
There's still large machine tools being refurbished in Rockford, Illinois, Haas is building a large new facility in Nevada (delayed; thanks covid) for making CNC machine tools, medical and aerospace parts are still earning machinists a crapton of money, and people are still hobbing enormous gears that are very, very expensive.
It's pretty clear that American machining has lost its production bandwidth due to offshoring, but it's not accurate to say that the field is dead.
"Big Oil’s Talent Crisis: High Salaries Are No Longer Enough
Energy companies scramble to attract engineers as young workers fret over climate and job security
Good news from the oil patch: Jobs are plentiful and salaries are soaring.
The bad news is that young people still aren’t interested.
Even as oil-and-gas companies post record profits, the industry is facing a worsening talent drought.
At U.S. colleges, the pool of new entrants for petroleum-engineering programs has shrunk to its smallest size since before the fracking boom began more than a decade ago. European universities, which have historically provided many of the engineers for companies with operations across the Middle East and Asia, are seeing similar trends.
And maybe that is also good news, because the youth realizes what we won't and what is at stake? Wouldn't have thought that not everything can be bought.. a little

The knowledge is all there, the problem is lack of experience/training.
Come on, you’ve got to at least offer them something other than what they’ve already been doing for years.
These things don't get built on a whim - there's risks, regulations, documentation, procedures, experts, etc. At the end of the day you have people doing the work for decades, with an intuition about how things work.
Given infinite time you can recreate anything - but by the time you're done putting the puzzle together you're out of business.
That's exactly my point. This intuition is undocumented however it becomes superseded by new tech. Nobody can (successfully) run a plastics plant with decades of old hardware knowledge and expect to be in business another 20 years.
"In 1991, Aldo retired and Ed took over day-to-day management of the company. First Plastics began the initiative to replace and update its molding equipment with new large capacity presses in 1995. This initiative has placed First Plastics as one of the most technologically advanced injection molders in the Northeast. Today it continues to add the latest technology while increasing its manufacturing capacity."
You would be surprised - I've seen production lines 30+ years old running profitably.
Note this was not plastics moulding - this was producing raw plastics/petrochemical facility.
You know, back when they had neither the plans nor people that had built such large engines before?
It's probably a myth anyway, Rocketdyne's expertise continues with the RS-68 and there are probably still employees that worked on the RS-56 that was derived from the H-1, which was essentially a smaller F-1
edit: Apparently, an upgraded F-1B is part of the SLS Block 2 spec anyway, so yes, they can still make them.
Gordon Ramsey can't document how to cook a steak and how to tell thats its done. 3 different cooks will read his instructions and will end up with 3 different steaks.
The idea that a lifetime of steelworking experience can be foind in books, especially by people who aren't known for love of books, is pure folly.
Skills are living. They live in flesh and bone.
> 3 different cooks will read his instructions and will end up with 3 different steaks
Either his instructions are shit, or the cooks are donkeys.
Sear steak at high heat, 1 minute, rotate steak 45 degrees, flip steak to sear back side for 1 minute, rotate steak 45 degrees. Move steak to indirect heat until internal temp probed at center of steak reaches 145F, remove steak and plate steak after resting for 4 minutes.
There. If you follow those instructions you can get a perfectly done steak every. single. time.
Shit is only subjective if you don’t have a repeatable way of measuring things.
You absolutely can learn steel working and foundry type of stuff from books, but you have to find ways of measuring what you are doing. E.G. heat to this temp, control cooling process by means of $X, $Y, $Z. Inspect crystal structure of coupon, X-ray for porosity.
It isn’t easy, but it can be done.
Can be? perhaps. Is documented? definitely not.
90% of code is not documented, whether it is a trojan or firmware for a soda dispenser. If I find you a random piece of code that was not maintained for the last 5 years, in a random language, what is the chance that you can get it to work? 30%?
> It isn’t easy, but it can be done
So most of the time it isn't done.
Its software engineer's job to document code, it is not the job of a machinist to document minitua of his job. In fact some proffeshions made historically a point of keeping their craft secret and passing knowledge on to an apprentice.
> Code and any process can be documented just fine.
I disagree, or at least think it's a lot harder than that.
1. It's not like we closed down Metal Cutting Inc. and just bought everything from China. There's no single company to have saved; there was Icebreakers and co. and Reactor Vessels Ltd. and ValvegearForgingCo. Any one of them might have been able to adapt but none of them were save-able and a lot of them were obviously obsolete.
2. Even when there is a Metal Cutting Inc., that's almost as bad. The supply chain was more efficient when it was integrated, not when its contracted out to a third party... or we would just buy from the places that still make things.
3. In this specific instance, but also in many others, market forces are not really the real problem. Look at Alcoa- hugely successful because small mills were cheaper to operate than large mills, but now we don't have huge mills everywhere. Can't fix that- even we had seen it coming and kept large mills alive, what would they make? What about harder problems,where you need a varied set of things to make to keep knowledge from dying out?
4. How do you do this without picking specific winners, and lobbying for who will live and who will die? If industries can survive the decline without losing their experts, how do you decide how much money to give them? How do you incentivize them to actually keep that knowledge, instead of getting into a more profitable industry?
5. In the end, the problem isn't about the companies or documentation or people. If you continued to employ all the people who operated the great presses, they'd just be mostly dead by now. It's not like people need much more than a wage, but I do think that an industry that depends on government subsidies, cannot possibly grow, does not build truly useful things, and could disappear because a new appointee dislikes it is not a line of work most people would be drawn towards.
My take is: Academia is the right place for some fraction of the people who are made redundant by outsourcing or technological change. They don't have to be lecturers, but they are already teachers. They pass on their knowledge to new employees. Document, research, experiment, and prove manufacturing and industrial techniques. Preserve that knowledge for when it is needed. Humanity doesn't invest nearly enough into education, much less the preservation of knowledge.
You probably mean just China. India's manufacturing output is less than 1/10th of China's manufacturing output.
Here in Germany, we're lacking cough syrup and antibiotics for children and so fucking much more drugs it's not even suitable for making jokes about the situation, it's so dire. Decades of "cutting costs" by always going for the cheapest manufacturer - i.e. China and India - has led to serious issues now.
Easy to know U.S. lost expertise, but tough question how do you get it back? Tariffs? A larger military-industrial complex? Even larger government?
if anything, that "I can just go" leads to more of a cult or prison than a dictatorship.
You don't need a centrally planned economy. Subsidies are enough incentive to at least keep a bit of production around.
> Easy to know U.S. lost expertise, but tough question how do you get it back?
Invest money into subsidies / R&D like in the icebreaker case, or raise tariffs against Chinese and Indian price dumping.
Currently US federal government spending is around 36% of GDP, which means 36% of the US economy is in fact centrally planned, albeit with some devolution in some cases.
64% of the federal budget goes to social security, medicare/medicaid, disability etc. That is, it goes to individuals. It's not meaningful to call that economic planning. It's not in the slightest like paying for defense contractors or research or infrastructure.
11% goes to interest payments, ie people who bought bonds etc. For individuals that's certainly not central planning, since they are the ones who decided to buy. A large amount goes towards paying of quant. easing etc, but it seems a little goofy to count that like we spend it every year still.
Non-meta: Why does the US have so few of these ships? Were more just not produced? I didn’t see an answer in the article but it’s possible I missed it.
Article mentions that as the polar ice melts there is MORE activity up there which increases the need for these ships. And the US is about to have just one left, which for some reason in down for maintenance in... the winter?
and the Great Lakes are Great -- bigger than you'd think, and highly traversed.
No need to ship goods from China to the West Coast through the Arctic.
The article speaks to that. The polar cap melting means thinner ice, which can in turn make sea lanes.
Simplistically, no ice is fine, thick ice is fine, but when there's "thin" ice you need ice breakers.
Russia doesn't have much in the way of non-polar coast (well, not the European end) so they've been breaking ice since forever. The US by comparison has very little polar coast and so less need for icebreakers.
Frankly, not sure it needs them at all except for bragging rights. Canadians maybe, but not sure about the US.
This is in the FAQ at https://news.ycombinator.com/newsfaq.html and there's more explanation here:
Things like energy independence sound cute and quaint until you find yourself being taken advantage of at best, or ground to a halt during armed conflict at worst.
Robust systems need some overhead.
That would depend on one's strategic goals and priorities. Personally, I do not believe the US should be the world police so I don't think it is necessary.
The post-WWII world order is predicated on the agreement that the age of imperialism is over and that invasion by force to annex another country is illegitimate.
It is obvious that all nations do not agree to this. E.g.: China on Tibet, Taiwan, 9-dashed line, etc., Russia in Chechnya, Georgia, Ukraine. Those authoritarian states think it is perfectly fine to use force or threats of force to occupy & annex other territories and peoples.
The fact that we also have global shipping and travel at a relatively low cost (cheap enough to make & ship goods petty much anywhere-to-anywhere, and international travel is available to non-elites), is a direct result of US Navy keeping a lid on piracy.
Anarchy, or unpoliced random aggression would be a very bad option.
So, if the US does not do it, who do you think would do a better job, Putin, Xi, Kim, someone else?
> The post-WWII world order is predicated on the agreement that the age of imperialism is over and that invasion by force to annex another country is illegitimate.
If that was true, it would be inconsistent with any one nation or narrow relatively fixed set of nations being the world’s police, as that would indicate that the age of imperialism was not over and that the world had a single imperial power or small group of such powers.
The central institution in the aspirational design of the order you describe had a solution to the problem: the UN would itself be the world’s policeman, via a centralized military command to which all member nations would subordinate command of designated units of their armed forces for the purpose.
This…did not work out in practice, and is one of the very many pieces of information suggesting that your accurate description of the aspirations which people at the end of WWII had for the postwar international order were never realized.
> Anarchy, or unpoliced random aggression would be a very bad option.
It would be, but its mostly what we have between the major powers, with the major powers (alone or in combination) policing everything else, with…issues where the policing desires of the major powers conflict.
Just like in past ages of imperialism.
The main difference is that the fact that the major powers are also nuclear powers exerts constraints on the form of their direct conflicts mostly to forms that are at least partially deniable to prevent pressure of uncontrolled escalation which could lead to nuclear annihilation.
Wide berth between an imperial power and one that survives on a system of alliances. Balance of powers realism works, but it’s far more brutal than a uni or bipolar world order.
> the UN would itself be the world’s policeman, via a centralized military command to which all member nations would subordinate command of designated units of their armed forces for the purpose
Many states have tried this. It never works. Either you centralise command. Or you get the Holy Roman Empire.
Yes, the UN failed to live up to that aspiration.
Of course some kind of Shangra-La where there is no conflict and no authoritarians trying to take over would be fantastic. The problem is that it is just that - a fantasy. We must deal with the reality of the world.
This is in no small part to the failure of including as permanent members on the Security Council the authoritarian states of USSR and China, which have done little but abuse the system attempting to game it for their own interests.
So, yes, we are down to a choice. Either:
1) The nations attempting (however imperfectly) to let their people live self-determining lives, and elect self-determining governments step up and enforce that aspirational world order as best they can.
2) Abandon attempts at suppressing imperialism and maintainting order, and allow again states to engage in war of all against all.
Suggesting that #1 is the same as imperialism, or as #2, is absurd.
We can seen where the policing has broken down, because the states trying to maintain democracy and the Post-WWII world order have tried appeasement or failed to police. It is endless war crimes, cities reduced to rubble, internment "reeducation" camps for millions.
So, if you are going to throw accusations that the US, UK, FR, NATO, attempting to maintain whatever peaceful world order is some kind of problem or is illegitimate, you need to come up with a better and viable solution.
What is your suggestion?
We’ve also seen where it succeeded in its real goals, which are often not democracy or any rules based order, but the parochial security and economic interests of the powers doing the “policing".
We've also seen that the power that holds itself up as the primary architect and enforcer of a “rules-based international order” particularly refuses (often with histrionic gestures, like the act nicknamed the Hague Invasion Act) to subject itself to the the rules and institutions of that order.
> It is endless war crimes, cities reduced to rubble,
Yes, we've seen that caused by the active engagement, not merely the restraint, of the “policing” powers.
> So, if you are going to throw accusations that the US, UK, FR, NATO, attempting to maintain whatever peaceful world order is some kind of problem or is illegitimate,
What I said was the suggestion that powrful countries policing the behavior of others is not imperialism but something categorically different is self-delusion.
Its others making the implicit claim that imperialism is illegitimate and what is legitimate is some other order that exists only in fantasy.
(I can certainly conceive if something that would be legitimate in a way that the imperialist order is not, but as I see no obvious pass yo achieving it, its not worth advocating.) But in the meantime, without a route out, the best way to mitigate the worst potential harms of the imperialist order starts with recognizing the nature of that order for what it is, and understanding where it is prone, by nature, to oroduce bad outcomes.
In economic theory there are good reasons to say that every country has better options than imperialism - but imperialism often looks easy.
I would suggest that “the age of imperialism is over only to the extent that what were among the last of the great imperial powers enforce that condition” is absolutely no different than “the age of imperialism continues, under some of the same imperial powers as its most recent previous form”.
Yes, when a central power (the metropole) dictates outcomes and behavior to other powers (the peripheries).
> which is not what we are doing
Its exactly what the upthread claim is that we are doing. I’m not as much arguing whether or not that is happening, as that the assertion that it is happening and that it is a constraint on imperialism is self-contradictory.
Why bother with the 'annex' part when you can just overthrow governments you don't like and replace them with ones you do?
Is it not? Afghanistan in 2002, Iraq in 2002, Haiti in 2004, Libya in 2011, the US is taking sides in the civil wars in Somalia, Yemen, and Syria, and there's whatever happened in Bolivia in 2019.
If those aren't recent enough for you, then it's mildly surprising you'd bring up Chechnya (under Russian (then Soviet, then Russian) control since the mid-19th century, most recent major operations ended in 2009), Tibet (annexed in 1950, previously under varying levels of Chinese control up thru the mid-Qing), and the Uighurs (Xinjiang / the Tarim Basin was first occupied by China as early as the Han dynasty and has been under Chinese control since 1884 (Qing then RoC then PRC)).

Move fast and break ice!
Why is steel necessary for ships?
From "Plant-based epoxy enables recyclable carbon fiber" (2022) https://news.ycombinator.com/item?id=30138954 :
> And once it’s completed you have an insanely strong material that makes steel look weak and brittle. It’s reported to be as much as ten times stronger than steel, yet is lighter than fiberglass
Make it out of hemp aerogel and you could carry the boat.
The front of an icebreaker's hull mostly faces compressive loads, with lots of shocks from hitting ice.
Try searching for "OceanGate Titan" if you want to read more about the performance of carbon fiber composites under large compressive loads in a marine environment.
> Have you here contested claims that hemp - biocomposite with resin - has greater Tensile Strength and Compressive Strength than steel and aluminum (and carbon fiber with sustainable binder)?
So you are talking about writing off tens of millions of dollars of a boat just because someone lost control and hit something too hard.
Steel is infinitely repairable, cut out the damaged section and weld in new steel.
Damage will and does occur to boats.
this is one of the narrow cases where pounds comes off the bench to say, "actually, you need weight"
(icebreakers slide/ride up on top of the ice and the weight of the ship breaks breaks it ice downward)
The imperial system actually does have a rather obscure unit called a slug which is equivalent to the kilogram (in terms of being purely a mass quantity) in the metric system, but since the pound already incorporates that term ( bundled together with the gravitational acceleration factor) it seldom sees action.
9.8m/s^2 at sea level, and it decreases with altitude all the way out to Lagrangian points where the gravitational attraction of the sun (and other local masses) is equal to that of earth; but solar pressure presumably displaces objects at zero-gravity rest.
Gravity is 'optional' with quantum locking. Gravity is a weak force.
Gravity is maybe the least lossy form of potential energy storage?
Don't skip boat throwing day!
