Making cement -- the most commonly used substance on Earth after water -- is responsible for 8% of global carbon emissions. It generates CO2 both through combustion of fossil fuels & through chemical processes. Sublime Systems thinks it has solved both sides of that equation. I talk with the CEO.
David Roberts is EXTREMELY practical, politically. He’s very no-nonsense, but gives clear and simple reasons for why he categorizes stuff as nonsense when he does. He’s not some techno-wizard optimist, but he’s also clear about how much tech we DO have and how much is achievable on realistic timelines if we just commit. He’s also clear about what the obstacles are, and even sometimes gives useful calls to action.
His most recent episode on nuclear is an almost perfect example of this. A lot of people are VERY enthusiastic about nuclear. He had Jigar Shah from the DOE on to talk about the field extensively – the upsides and downsides, what technologies work and make sense, what technologies are just mis-advertised, what technologies are total vaporware, why it’s so hard to build nuclear in the US (hint: it’s not the anti-nuke environmental lobby), and all that. Fabulous interview.
I definitely trend towards doomerism on all this stuff, but it’s good to be reminder the tech really is there decarbonize a LOT and VERY FAST, and probably even achieve planetary net zero or even net negative within my lifetime. Just have to convince people the juice is worth the squeeze – which it undeniably is when the entire ecosystem is at stake.
Now that I’ve found a neat community here in beehaw, I plan to share and David Roberts work extensively because the stuff he puts out is what gives me hope

A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.
Highly recommend Volts to everyone interested.
