Sidd comments on Cost of Space Weather Hardening

[Sidd]

Thank you! I’m a big fan of your work on nuclear war resilience.

While this article is pretty good about describing what costs are imposed by solar flares, it doesn’t get at the cost of hardening. Do you think there is an actual numerical estimate anywhere?

Thanks! There’s this estimate in the LW article:

Meanwhile, protecting the grid’s “6,000 most critical transformers” with SolidGrounds would cost 3-4 billion dollars to the US. That’s 0.3% of the 2021 infrastructure bill, recuperable within the year!
