They had a big "overbuild" of apartments in the 2010s, which was great for affordability. Now imagine if we did that consistently...

Since 1945, a republican has been mayor of NYC for 16 years out of 80. And that's when they were less insane.

They're paying so much attention to it because it almost certainly decides the winner.

Love the back of the envelope analysis. My other worry is what other "frivolous" electricity use (AI, crypto) we will encourage with the cheap electricity we are (hopefully) going to produce.

It has been, it's just so absurdly irrational in a long term manner that there's not too many who are keen to bet against it.

It remains irrational longer than people can afford it.

Great analogy. I like comparing it to broken windows - they're moving from breaking 100 windows per night to 90, so they get credited 10 windows.

They gave me one hell of a fright when I first came across them while going for a run

Feels like this is going to be bloody expensive and not flexible as it only gets you between two points (but kind of cool).

Would be a lot better to put congestion charging in the center and use that to fund better public transport instead

I'd recommend looking at work from ICMM and their CEO, Rohitesh, there's good stuff there, especially coming from within the industry

From 24 to 25,000: Making responsible mining the norm
Is mining truly transforming—or just talking? At UNECE Resource Management Week 2025, ICMM President and CEO Rohitesh Dhawan delivers a candid response.

Are you talking about heap leaching? Freeport is making advances there, comes with it's own issues no doubt

Freeport furthers its leading copper leaching excellence - International Mining
A Freeport spokesperson confirmed to IM that the company was in a trial of the Jetti technology through “a commercial installation” at its Bagdad mine in Arizona, USA

Tailings dams and water use are two of the biggest environmental issues with mining and they can both be significantly improved with water recycling, which is technically possible, but often not economical. How can this be fixed? especially considering the geographic diversity of mines.

- how do we align the short term focus of VCs and other investors with the long term outlook of the mining industry (economically and environmentally). Pollution that occurs last generations and companies just don't think in that timeframe

Fantastic question. Only alternative at the moment is state owned

When/if we get through this current far right fling, liberal democracies need to take a good hard look and figure out how to actually be effective again

I hate to say it, but without China we'd be in a lot worse place when it comes to the climate crisis. Their work on PV, EVs, and batteries is the only real glimmer of hope in decarbonizing our world.

I think those experts are often just happy to share their hard earned knowledge with someone who appreciates it and can ask good questions. It can be lonely at the top of your field!

Why is 330MW hydro a tenth of 600MW hydro? I guess there might be some "tipping points" as you scale up, but an order of magnitude is wild

Not a fan of posts like this. Yes AI has its use, but the sheer energy demand of "nonsense" AI far outweighs these benefits.

This pro-AI stance that the IEA has taken recently screams of industry capture. AI is an energy problem looking for a solution.
