Hi, this is Rob, founder of Prometheus. The conversion of CO2 and water to gasoline is not a super efficient process, likely 50-60% at best in the near term, but that's ok, if the electricity is from a zero carbon source like solar or wind, and the cost of the electricity is low (which these days it is).

The CNT membranes are being made at full commercial scale now by my previous startup, Mattershift. Ready to go!

We've got scientists and engineers from national labs and previous efforts like Project Foghorn at Google. Hope to share some new hires soon.

There was a podcast that was associated with the article, that runs 21 minutes and goes into more details: https://megaphone.link/BLM3585271197
