On July 23, @CJHandmer provided an update on Terraform Industries' hardware and process to produce synthetic natural gas from solar power and air. "Other than plants and some cyanobacteria, I believe this is the first ever commercially useful capture and production of CO2 at scale." This is very exciting, clearly more than a minimum viable product.

(Terraform Industries in Burbank, California is not to be confused with the HashiCorp product. https://www.terraformindustries.com/

Are there competitors in this space?
