Between 1950 and the 1980s nuclear grew rapidly, from 0 GW to more than 300 GW of installed capacity. And then it levelled off, in the aftermath of Three Mile Island and Chernobyl. It’s only 400 GW today, and provides about 10% of world electricity.

The bad news: we don’t have cheap, scalable NETs :-) I do think this is a wonderful research opportunity, though, and my impression is that it’s very under-invested in.

5. Final thoughts: I’m repeatedly struck by the incredible size of the opportunity here. We’re going to make much better institutions, discover many amazing things, & create incredible companies.

I know some people don’t like the last, but think it’s good when groups of people profit from providing an enormous social good, like scalable clean energy, or carbon removal. That's capitalism operating as it should, to serve the social good. I hope it does here.

Of course, the flip side: there’s damage already being done, and likely to be incredible damage done.

We don’t yet have institutions or norms that enable us to deal with problems where inaction over the next few decades may cause much of an ice sheet to melt a century or two from now. I hope we can develop such institutions and norms!

I'm curious: methane capture only rarely seems to be considered an option. Is there a reason for that?
-
In part, I'm sure it's because methane lasts much less long in the atmosphere (more like a decade). For me, at least, it's just a question of only have so much time, & making choices!

My gut feeling is that there ought to be deep thermodynamic reasons why carbon capture is either slow or energetically expensive. Gaseous CO2 is a high entropy endpoint. It seems like it’d be inherently energy expensive to lower that entropy.
-
I suppose I can believe that the energy released from polymer bonds might be orders of magnitude larger than the energy required to separate CO2 from air and compress it somewhere, so that it’s not like trying to reconstitute oil from the air, but still it feels hard.
