  •  The same also applies to the nickel catalyst. (5+ / 0-)

    Nickel nanoparticles would, of necessity, be produced from pure nickel (probably involving the Mond process to obtain it) which would be both expensive and would drive the world demand for the metal through the roof. Even given the idea that the nickel could be reused in the sequestration process, it would still require massive amounts of a metal that we already use extensively. Nickel mining isn't exactly carbon-neutral either, nor is it without other environmental impacts.

    This process might be useful, but let's not jump to the conclusion that it's the next big thing until we know all the ramifications and impacts involved.

      Another reason to start mining in space maybe?

      •  It's a fine thing in itself, but... (0+ / 0-)

        getting that nickel (or anything else) back down the gravity well in usable form is another matter entirely. But then again, so is getting what we'd need to do mining in space up the gravity well in the first place. Until we build a beanstalk or an electromagnetic launch system (both a very long time off), I don't see it happening.
