Note that this future, as well as requiring insane amounts of super cheap electricity, also requires someone to figure out cheap direct air capture of CO2. No

  For what it's worth, I think they (as in Terraform) intend to also tackle that part of the problem. I think one advantage they have over current DAC approaches is that since they're going straight from their capture material into their methane reactor, they are both creating a valuable output from their carbon capture (where as most current systems need to add sequestration costs).

  There's a lot we can do with hydrogen alone. But yep, carbon capture from the air is very important.

  That is literally what Casey Handmer, author of the post, has a company working on, because he’s accurately projecting the exponential solar energy increases coming.

  > Cheap direct air capture of CO2. What is wrong with trees or algaes? Seems to me it doesn't get much cheaper than that.
