Casey Handmer

Australian-American physicist and entrepreneur — former JPL scientist — who writes about space, energy, and technology with unusual analytical depth — co-founder of Terraform Industries (using solar power to produce synthetic natural gas from air).

Creates the analytical case for direct air capture of CO2 using solar energy — Handmer's Terraform Industries bet (that cheap solar energy can produce synthetic methane from atmospheric CO2 economically) is one of the most interesting direct air capture approaches because it uses no novel chemistry, only scale.
