Laser CO2 sequestration

Can this new discovery transform CO2 to O2 from industrial emissions

If vacuum ultraviolet laser can make CO2 to into C and O2 why doesn't the article suggest this could be used to "clean" coal plant emissions?

       // my old proposal - grow lots of wood, burn it until it turns to charcoal and bury that //   

       That might be a fine idea at some point in the future, but as long as we're still mining coal and burning it in power plants, it would probably be better to burn the charcoal than to pay one crew to bury the charcoal while another crew is being paid to mine coal.

       Each gallon of gasoline creates about a gallon of water so <shrug>   

       Re: the idea - if it could be done with any sort of efficiency, it'd be a good idea. Lasers aren't efficient, though.

       Wrong. If it could be done with 100% efficiency it would still be a bad idea. You would, as pointed out, use as much energy as had been produced by burning the coal.

       Well, if it was solar powered...that'd be green-ish. Reminds me of those guys out in the desert with a huge solar array making H2O and CO2 back into petrol..   

       A quick search brings up many doing that..link

       coal phht, though there is some H in there; I meant methane or gasoline/diesel.

       Yeah, the thermodynamics would suggest not so much a laser as a *really* tall chimney, so that the sun could do the work directly. I'm sure we could spread the costs by thinking of other things to do with the chimney once it was up. Maybe we could sell postcards at the top, have a revolving restaurant, that sort of thing.
