For a lot of the more rural towns (or a least for the ones I know of) that do have rail connections, they are only accessible using diesel locomotives as there is no electricity network set up to power electric trains. So if we don’t want to introduce more emissions from rail freight we would have to electrify the whole rail network.

Hydrogen (and battery) are both viable energy storage methods for heavy rail freight:

It's important that shitty things don't surprise us out of nowhere, that there's a history of calling out the red flags on something like this while it was in development; eg: https://lemmy.ml/post/139820

Regardless, Sydney Criminal Lawyers undertakes journalism to publish news articles, much like civil liberties defender EFF or entertainment/advertising company Nine/Fairfax.

About the author, from the article's page:

Paul Gregoire is a Sydney-based journalist and writer. He's the winner of the 2021 NSW Council for Civil Liberties Award For Excellence In Civil Liberties Journalism. Prior to Sydney Criminal Lawyers®, Paul wrote for VICE and was the news editor at Sydney’s City Hub.

Quoting from https://lemmy.ml/comment/3470836 (@[email protected]):

Wait.

1/ publishing evidence of the Clinton campaign actively undermining Sanders who was then the natural candidate of the Democrats according to their internal polls (including by using antisemitic slur) + actively boosting Trump campaign because “it’s the only one we can beat” is “throwing the US presidential election to the Republicans”? How this genuine, authenticated information of public interest, published in the New York Times and WaPo is throwing the US elections more than the facts that were being reported?

2/ “worked with Russian intelligence” is absolute nonsense. What is your source on that? The Muller report says the opposite. If anything it is possible (but not proven) that the source may have been from within Russian intel, but a) Assange mentioned several times -way before that episode- that the entire architecture of WL made it impossible for them to actually know their sources, and we have all reasons to believe that (as it would be the smartest thing to do) b) if any journalist gets documents that are authentic and of public interest, regardless of the source, their duty is to publish it. If a Russian intelligence source had provided fake, doctored or otherwise altered material, and they would have been published as such, it would have been a real scandal. In the facts we are still talking of ground-breaking journalism.

I still can’t figure that some people cannot realize that Hillary Clinton did all she could to actually lose this election on her own (this and a fundamentally fucked up electoral system), and are actually finding scapegoats like Assange to avoid looking at this reality in the eyes…

So.. I really don't know chemistry, and these aren't the highest quality references, but here goes:

  • 4 mol of iron in a heat pack provides 1648.4 kJ of heat. ^[1]^
  • 4 mol of iron weighs 223g. ^[2]^
  • Recycling 1000kg of steel saves 642 kWh of energy. ^[3]^
    • Recycling 0.223kg steel saves 642 * 0.223 / 1000 = ~ 0.143 kWh
    • 0.143 * 3600 = 515 kJ

Huh. So maybe heat packs are a reasonable use of scrap iron's embodied energy after all. Assuming you have a sufficient source of uncontaminated steel filing waste and that it's economical to collect and process into heat packs.

...But only if you're heating your water using fossil fuels using an inefficient method! If your water is heated using solar or waste heat capture or a heat pump^[4]^, which would swing the balance way over to hot water bottles again.

You're not considering the energy required to smelt the iron.

Iron filings (in a collected quantity high enough to make manufacturing these heat packs worthwhile) are not a waste product, they are recycled -- saving the smelting of that much new iron.

Sawdust+iron heat packs are a very useful and non-hazardous product, for sure, but aside from situations where a hot water bottle is impractical, hot water bottle still wins.

I think Assange is a legendary journalist who (to put it mildly) is bearing the brunt of a fucked up assault on the free press by CIA/etc.

Nothing at all! If anything I mentioned it as a point of approval from me, and stating them to clearly not be in the same camp as the banned-from-twitter-because-right-wing-extremists.

I don't think it's that kind of banned from twitter. The figures behind it seem to associate themselves with Wikileaks and/or Julian Assange. Suzie Dawson, for example, is hosting the video presentations about the plaform.

To be clear I don't mean to shit on the platform, I'm just approaching it with a lot of cynicism. I want to understand what it is and its problems and merits.
