The space shuttle contain a huge reservoir of liquid hydrogen at very low temperature creating extremely difficult engineering stresses.
So, insurance cost will be sky high if ever such planes take commercial flights.

Do you know how brittle metals become at very low temperature ? Did you notice I did not talk about hydrogen explosiveness ?

But sure, let’s now talk about explosiveness. Do you know the mixture ratio range is completely different (much greater) for air + H2 explosive mixture as compared to other mixtures ? You are very far from an expert on the topic aren’t you ?

Detonation
“A very wide variety of fuels may occur as gases (e.g. hydrogen), droplet fogs, or dust suspensions. In addition to dioxygen, oxidants can include halogen compounds, ozone, hydrogen peroxide, and oxides of nitrogen. Gaseous detonations are often associated with a mixture of fuel and oxidant in a composition somewhat below conventional flammability ratios.”

For Hydrogen, if I recall correctly, the explosive range is from 4% to 75% hydrogen in air. I may dig a little bit more to find sources.

How many more false experts want to comment on this ? And feel free to downvote, you only underline your ignorance and arrogance.

LEL for Hydrogen: 4.0 (% in air)
UEL is 75 %
This is the most severe (wide range) for any fuel.

This is on top to hydrogen enbrittlement and low temperature enbrittlement of metals.

Good luck with the insurance fees for commercial flights.

I agree…

Air Liquide is the supplyer of the hydrogen. You have green and blue hydrogen. One is produced with reformation and carbon capture while the other one is produced with electrolysis. So, if the electricity is from renewable then it’s technically zero emission.

I agree with what you say and that any and all definitions are somewhat incomplete …but still.
Even though, for example, you could find any degrees between a chair and a table ; you could create something quite exactly in between a chair and a table, well, despite this, it is still useful to define what’s a chair and what’s a table.
Now, about “Jim fucking Pillin” well, I cant say anything ; I’m disconnected of the topic.

P.S. :

based on my previous comment :To : @Wogi average : here it means the average man versus the average woman. I know everyone here gets offended and rightfully so. But I find it so stupid because they are not offended for the right reason. (to @HeartyBeast as well) By the way ; if you had to define woman and man, what would you say ?

A_A , 10 months ago (edited 10 months ago)

@HeartyBeast I like what you say : both definitions are interesting. Please notice the one based on self-identification is quite in fashion since 5 or 10 years but like all fashions it should subside a bit in the coming years, I mean at least in the western world (i think). When (if) this happens, the definition based on phenotypes will be seen as more important …it’s not just important for medical application : this is an oversimplification (of course).

P.S. : in response to your comment :

spoilerI’m offended because it is so daft. If I had to define a man and a woman, I would say that it is currently difficult as there are two definitions, one being based on biological sex (which is itself a surprisingly ticklish concept) and the other based around gender and self identification. Personally, I’m happy with the latter. The former is useful in medical contexts.

A_A , 10 months ago (edited 10 months ago)

Now this is the point and this is what should have been the top comment(s). When I wrote my (obviously stupid) first comment, the other top comments were (then) not about that at all. Was (instead) just about avoiding the word of the post. Sorry for all this.

P.S. : That stupid comment of mine was :

spoilerGet offended all you want but read this :
>…“on average”…
( that citation is from the post )

A_A , 10 months ago (edited 10 months ago)

Thanks 😊 These are the best world I think I ever got on the Internet. I try to be better (and make others so) which means sometimes exposing my ignorance (or that of others).

P.S. : in response to this kind comment of yours :

It takes a smart person to change their mind, and a strong person to admit it publicly. You’re a good egg.

@VinceUnderReview @vinceman

Google the words “gender bias”. I’ll wait.

Sexism (as defined below) is bad.

SexismSexism is prejudice or discrimination based on one’s sex or gender. Sexism can affect anyone, but it primarily affects women and girls.[1] It has been linked to gender roles and stereotypes,[2][3] and may include the belief that one sex or gender is intrinsically superior to another.[4] Extreme sexism may foster sexual harassment, rape, and other forms of sexual violence.[5][6] Discrimination in this context is defined as discrimination toward people based on their gender identity[7] or their gender or sex differences.[8] An example of this is workplace inequality.[8] Sexism may arise from social or cultural customs and norms.

Nevertheless I stand by what I wrote above.
What’s your point ?

P.S. : My previous comment was :

it’s even more controversial to discuss the three percent IQ difference in (average) intelligence between men and women. For example, see how this comment will be downvoted, even if it is true.

A_A , 10 months ago (edited 10 months ago)

@SpaceCowboy

Yeah doesn’t it really suck when people use some arbitrary point system to indicate that you don’t quite measure up to others?

I like it in here. I like Lemmy. I like being sometimes upvoted or even I like being downvoted because I can understand why what people think. Sometimes it will make me change my mind or at least re-think (reconsider). Sometimes I know I will be down devoted and I post anyway just because I want the conversation to rise (to move) in some direction.
For me it’s no more arbitrary than when talking with someone and seeing if they smile or if they frown.

P.S. : my previous comment in this tread was :

@Nougat believe there is now a bug, at least on my side : the post does not show correctly and I can’t see my comments anymore. Or maybe my comments were removed (?) I don’t know.
Because of this I will make a copy of your comment here :

your commentFrom : @Nougat
>Ah, I just thought of something. >“Man” and “woman” are archetypes. Not descrptions of objects, like “table” or “chair” – instead, like “hero” or “villain” or “aristocrat” or “scoundrel.” >All of us have an archetype we identify with; some of us have a physical appearance or characteristics that don’t match the archetype we identify with. Some of us feel that it would benefit our mental health to have our physical appearance match more closely with the archetype. Among other things, it makes it so that other people are more likely to see us as us, rather than seeing a person who isn’t us. >Not being seen is deeply traumatic. If one’s physical characteristics cause them trauma, those characteristics should be considered disabilities, and we should welcome resolutions to them from medical science. >Some of us identify very strongly with one of “man” or “woman,” others more weakly. Some of us are in between somewhere, or switch back and forth depending on the day. Or don’t identify on that gender spectrum at all, or in some other dimension not represented by those two points. >That’s why we call people what they want to be called. I’m not going to pretend that it’s easy to get your lizard brain to really see some of us as “men” or “women” when the physical appearance doesn’t match our expectations. But just using the correct language goes a long way towards communicating that you want to see them, and by extension, reduce their trauma. >Now that you know this (and of course, if you agree), you must grapple with the fact that misgendering people is traumatic (which is to me a reminder to try harder every time), and that misgendering people on purpose is simply cruel. >Side note, I made a point through this comment to refer to us instead of the more arm’s length “some people, other people, these people, those people.” We are some people, we are other people, these people, those people

I have an old mind and I live in an old world where woman and man are quite very much as defined as table and chair. Not perfectly defined, with many exceptions, but still.

One notable exception I wrote to @vlad76 :

XY gonadal dysgenesis : They are many case of XY chromosome embryos that becomes real woman : biologically and genitally. I believe (?) there are also cases of XX becoming (real) men (I am not sure).

@Wogi wrote in here 6h ago :

There’s no legal reason to define the genders, no ongoing court drama in Nebraska that hinges on this definition, nothing legally will ever be decided because of it. It’s just one idiot shouting out to a bunch of other idiots that he doesn’t like it when people who were born with one set of genitals want to have a different set of genitals.

What this will accomplish is added brain drain, an issue Nebraska sorely needs a remedy to, it will cost millions in court cases that will now be filed against the state and the governor, and it will cost women’s centers in Nebraska Federal money. All while doing absolutely nothing worthwhile for the state of Nebraska.

It’s Jim Pillen saying he wants a fight with a minority group. And it’s an idiotic call to arms at that.

N.B. : This excellent comment was unfortunately part of a thread which was deleted by the mod. I read the other comments in this post and, compared to the above, they’re mostly not worth one cent.

When I use my (Android) phone I very much feel that I am not the customer but rather the product and it would be much worse (I think) if competition wasn’t there. in some ways, my experience with one (bad) Chinese phone was much better than what I had with one from South Korea.

Semiconductor Manufacturing International Corporation (SMIC) is a partially state-owned publicly listed Chinese pure-play semiconductor foundry company. It is the largest contract chip maker in mainland China.

…SMIC ordered an EUV step-and-scan system from ASML Holding for $120 million in 2018. The order was blocked after the US government lobbied ASML and the government of the Netherlands.

if to save a life I would (no doubt) gently push that stupid car out of the way. Wouldn’t you ?

A_A , 10 months ago (edited 10 months ago)

lol. You don’t know much about mechanics… do you ? And ambulance is a truck and it is heavy. You would be right if the vehicle to be pushed away was not so light. Anyway, you can feel it when you start to push how the vehicles reacts.

A_A , 10 months ago

I guess you and I know more about mechanics than the average person 👍

A_A , 10 months ago (edited 10 months ago)

Evidence here show that ambulance - - could have and should have - - passed to the right.

Yet, the (hypothetical) question remains :
if to save a life I would (no doubt) gently push that stupid car out of the way. Wouldn’t you ?

Edit : to @EdibleFriend@lemmy.worldDear lemmy user,
Something went wrong in the other tread where you stated that pushing a light car with an ambulance could break the ambulance while I was of the opinion that since the ambulance is a truck and Heavy it would go right and anyway the driver of the ambulance should be able to judge if those vehicles reacts in the right way.
Maybe you want to continue our discussion about it ?

French-Québec : “Kossé ça?”
French also : “C’est quoi?”
… or : “Qu’est-ce?”

Word for word of "qu’est-ce-que c’est ?” …
…goes like : "What’s this that this is?
…or : “What’s this which this is?”

“Qu’est-ce?” sounds like the english “Case”.

At the time I made my first comment in here, there was no word from any admin, so, I had that (hypothesis //hunch //educated_guess) whatever you may call it. And then I wrote : “time will tell”. Well, I had the confirmation I needed for that L.W.Admin.

Finally, if you need some more information, you may search it by yourself - - I have nothing more to say.
