The UK is trumpeting #rail200: the 200th anniversary of the railway. As @markhburton points out, that’s a bit premature: https://mstdn.social/@markhburton/113803780435711720

But I want to re-up Kris de Dekker’s lens.

If we were serious about constructing a low carbon economy, we’d acknowledge, soberly, that we have a steel problem:

“The global iron and steel industry consumes more energy and produces more carbon emissions than any other industry.”

Some notes from Kris’s excellent analysis follow…

2025 is being celebrated as the 200th anniversary of the birth of the passenger railway. A bit premature, although there was a one-off excursion on the Stockton and Darlington railway, with passengers traveling on coal wagons, the regular passenger service from 1825-1830 used horse-drawn coaches. In 1830, the Liverpool Manchester railway opened, the first connecting 2 cities and the first scheduled passenger service.

@urlyman @markhburton I wrote about this four years ago. We're really going to struggle, in the medium term, for sufficient structural materials, especially steel, and we cannot, as a society, afford to be profliigate with it.

There's a researcher called Simon Michaux who has done a lot of work on this.

Where's the Steel?

From the discovery of iron working techniques, about 3,200 years ago, up until the widespread exploitation of fossil fuels, about 250 years ago, iron and steel were rare, precious materials. The average person, across the whole world, almost certainly had less than 500 grammes of it. A knife, probably; some tool of their trade, possibly. Even members of the elite — warriors who fought in full armour, for example — probably owned no more than 30kg of iron and steel.The use of fossil fuel changed all that, of course. There's about one car for every two people in the UK, and the average car now weighs 1857Kg, so that's almost a ton per person in cars alone, not to mention all the steel we now have in buildings and infrastructure. But it's fossil fuels that have made that possible. In future, we can't use them. So how much steel will we have?

The UKFIRES Report 'Absolute Zero' is also good and concise on steel. https://www.repository.cam.ac.uk/items/33aaf353-b7de-45b0-9c40-5f62975b2127
Absolute Zero

We can’t wait for breakthrough technologies to deliver net-zero emissions by 2050. Instead, we can plan to respond to climate change using today’s technologies with incremental change. This will reveal many opportunities for growth but requires a public discussion about future lifestyles.

@markhburton @urlyman See, that report is all simple common sense, and yet no political party -- not even the bloody #Greens -- are even trying to sell this vision. It's a good vision, it would work, and if we adopt it RIGHT NOW there is (just) still time.

Why isn't ANYONE pushing this?

@simon_brooke @urlyman Indeed.
We used it in the Getting Real report. Sent a year ago (if my MP's office did what they said they had) to approx 80 potentially sympathetic parliamentarians and separately to policy people, not one of whom even acknowledged it

Sorry but I read a lot of PDFs. Why do you say they are 'basically unreadable'…??

@MichaelLondonSF @simon_brooke @markhburton @urlyman they don't reflow to my device width, adopt my fonts or colors. Also the vast majority of academic ones seem to be two columns per page which should be illegal for something on the web

@falken @MichaelLondonSF @simon_brooke @markhburton @urlyman I echo this - recently I have started to find reading on a led screen kind of eye straining for long periods of time and I prefer to push long form writing to my ereader or enabling my browser's reader mode. But PDFs don't work with reader modes, and scaling an A4 sheet down to an A5 display means either I have to faff around with trimming margins and splitting columns or zooming and panning the page on an ereader with a slow refresh rate.
