I mean it would have been nice to get this earlier but I'm somewhat impressed.
Natural gas is a dirty fucking lie. Leaked methane from natural gas extraction and transportation is orders of magnitude worse for the environment than carbon dioxide in the short term (20-year to 100-year horizon).
It's technically better past that, but by that point we'll all be dead or underwater anyway.
It also breaks down to CO2 after, right? A small amount but still.

What I find truly amazing is that they have found a way to produce all the technology required for this system without any emissions!
