I also have looked at the idea of spinning gold from straw...

Even looked at ultra short pulse lasers since I have worked with them a lot...

There is no way I can see of getting past the energy costs. Breaking apart the CO2 will require more energy than was produced in its creation in the first place.

- All theser schemes for eliminating CO2 through technology are bogus. - ER - 11/9/2023 2:58:32 AM
  - It's just not going to happen. - podrock - 11/10/2023 2:59:04 AM
  - I think you're missing the point - BuckGalaxy - 11/9/2023 3:39:14 AM
    - No, Rob. YOU are missing the point. - ER - 11/9/2023 2:35:17 PM

        I would have taken that as a compliment. - ER - 11/11/2023 4:19:29 AM
        
        And I took it as a compliment you referred to me as Rob - BuckGalaxy - 11/12/2023 7:06:47 PM
        
        Thanks Buck - RobVG - 11/12/2023 8:45:36 PM

        You know, - podrock - 11/10/2023 3:03:36 AM
        
        a hell of a lot - BuckGalaxy - 11/10/2023 5:56:00 PM
        
        I'd have to look that up. - podrock - 11/11/2023 1:28:41 AM
        
        I doubt it is a drop in the bucket compared to what we intentionally burn... - RL - 11/12/2023 8:17:13 PM
        
        Did you mean you "doubt it is more than a drop in the bucket..."? - BuckGalaxy - 11/12/2023 10:42:04 PM

        Agreed, but clean energy is not enough... - RL - 11/9/2023 8:55:27 PM
        
        I fully agree - BuckGalaxy - 11/9/2023 9:02:06 PM
