Need a coal dusted fell-for-it-again

Same thing as wałęsa. They are kinda similar in more aspects just that Trump is coming from lumpenbougie and wałęsa from lumpenprole.

Only tangentially related.

Why do we still mine coal? Coal mining, from what I hear, is extremely destructive, not only to the environment, but to the body. Compare that to charcoal, and while it's still pretty dirty, it doesn't require smacking a pick onto a rock that spits toxic dust into your face. The process to make charociaI is also inherently contained, as it requires you keep the wood in a small space with no air flow. I mean, looking online, I barely see any differences between coal and charcoal. The most I see was one Reddit comment saying "coal burns longer."

Steelmaking requires huge amounts of coal. Early British steel industry used charcoal and deforested most of the island in the process, and now we produce several orders of magnitude more steel globally. We simply don't have enough forests.

Good point, comrade. Thanks for bringing it up!

[-] mactan@lemmy.ml 8 points 5 months ago

antiquated steel manufacturing processes depend on the use of coke, which is the charcoal of coal

[-] GamersOfTheWorld@hexbear.net 5 points 5 months ago

Let me guess, it's one of those situations where there is there is a better method available but nobody has invested in the infrastructure to use this new method?

[-] fox@hexbear.net 11 points 5 months ago

Steel production emits something like 1.4 tons of CO2 per 1 ton of steel made. The steel industry is responsible for about 8% of global carbon emissions. Not only for the high temperatures required but because carbon is used to reduce iron ore to pure iron, and because carbon is a component of steel alloy. Liquid natural gas is used as well, and there's a "green" version of steel production that uses hydrogen instead of carbon to reduce the iron ore. But today almost all hydrogen is produced from natural gas.

Yeah, it's definitely a fuck. doomjak

I was just saying that there might have been a better way to do it but since Porky doesn't care about "better" it's never been done, yk?

I've definitely seen big electric arc furnaces in places like China and Korea, although i don't know if that's only for steel recycling. Hopefully with how many fucktillion watts of power China is producing now, they can figure out an all-electric method of steel production.

China developed a flash ironmaking method (3600 times more productive) that removes the dependency on coke

The team also revealed that this new ironmaking technology could improve energy efficiency in China’s steel industry by over one-third, further enhancing its environmental sustainability and cost-effectiveness. It is also expected to enable the steel industry to achieve the coveted goal of ‘near-zero carbon dioxide emissions.’

Welcome to c/news! We aim to foster a book-club type environment for discussion and critical analysis of the news. Our policy objectives are:

We ask community members to appreciate the uncertainty inherent in critical analysis of current events, the need to constantly learn, and take part in the community with humility. None of us are the One True Leftist, not even you, the reader.

Newcomm and Newsmega Rules:

The Hexbear Code of Conduct and Terms of Service apply here.

  1. Link titles: Please use informative link titles. Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed.

  2. Content warnings: Posts on the newscomm and top-level replies on the newsmega should use content warnings appropriately. Please be thoughtful about wording and triggers when describing awful things in post titles.

  3. Fake news: No fake news posts ever, including April 1st. Deliberate fake news posting is a bannable offense. If you mistakenly post fake news the mod team may ask you to delete/modify the post or we may delete it ourselves.

  4. Link sources: All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. If you are citing a Twitter post as news, please include the Xcancel.com (or another Nitter instance) or at least strip out identifier information from the twitter link. There is also a Firefox extension that can redirect Twitter links to a Nitter instance, such as Libredirect or archive them as you would any other reactionary source.

  5. Archive sites: We highly encourage use of non-paywalled archive sites (i.e. archive.is, web.archive.org, ghostarchive.org) so that links are widely accessible to the community and so that reactionary sources don’t derive data/ad revenue from Hexbear users. If you see a link without an archive link, please archive it yourself and add it to the thread, ask the OP to fix it, or report to mods. Including text of articles in threads is welcome.

  6. Low effort material: Avoid memes/jokes/shitposts in newscomm posts and top-level replies to the newsmega. This kind of content is OK in post replies and in newsmega sub-threads. We encourage the community to balance their contribution of low effort material with effort posts, links to real news/analysis, and meaningful engagement with material posted in the community.

  7. American politics: Discussion and effort posts on the (potential) material impacts of American electoral politics is welcome, but the never-ending circus of American Politics© Brought to You by Mountain Dew™ is not welcome. This refers to polling, pundit reactions, electoral horse races, rumors of who might run, etc.

  8. Electoralism: Please try to avoid struggle sessions about the value of voting/taking part in the electoral system in the West. c/electoralism is right over there.

  9. AI Slop: Don't post AI generated content. Posts about AI race/chip wars/data centers are fine.
