Doesn't pass basic thermodynamics.
If this finding is worth it, strap the machine doing it onto a car with methane motor (already exists) and you'll have an Perpetuum mobile.

It is directly addressed.
Excess solar power pulls excess co2 from atmosphere, and puts it into methane, which is stored.
It can then be sequestered (carbon captured), or burned (carbon neutral energy storage).
So its not a game changer, its barely even relevant to the CO2 levels. Might have some applications but its not the solution it is presented as (Like the previous "solutions" that cropped up every other week on HN and are now long forgotten).
