    I'm just wondering how viable a solution it would be to try and find ways to eject CO2 into space, rather than try and re-capture it into the ground. If we did it carefully enough, it would have the added benefit of providing us with Carbon for any space/moon colonization goals we might have.

    But is it feasable?

    Just gonna throw some ideas out here, and feel free to rip them apart (I might learn something from it)

    1) - Find a frequency of light that mostly affects CO2 only, and bombard sections of the upper atmosphere with it, in hope of energizing single CO2 molecules into speeding up and departing into space.


    2) - (If we ever have a strong Moon presence) send rockets back into low Earth orbit so they come just close enough to the atmosphere to scoop up some air, then have them bring it back to the Moon with them.


    3) - Combine ideas #1 and #2 by putting satellites into near Earth orbit that emit a frequency of light designed to excite CO2. Even better would be if we could direct where it would go once it had been set free. ( If they were solar powered, we might not even have to worry about where the energy is coming from. )


    Anyways, I kind of know this whole concept is absurd, but it would be really interesting to hear if anyone had a serious perspective on it.

    Can we discuss some commercial product which can be made out of CO2?

    Fizzy drinks come to mind

    Still I guess thats only a temporary reuse. The idea of jettisoning nuclear waste into space has also be posited but the energy required might be comparable to the energy derived from the fuel. There has however been talk of a "space elevator" that would use a carbon nanofiber tether into space. This, if built, could be very energy efficient and use energy on the elevator ride up, and return energy on the way back down.

    However I do like the idea of converting into other compounds, presumable by adding Hydrogen to make hydrocarbon compounds. Providing the energy required to do this does not generate more in the process (relative to the amount converted) then the idea should be worthwhile pursuing.

    (Or perhaps we could just plant more trees or something - with just a bit of sunlight they convert to )

    I guess the problem is overcoming the temptation to burn whatever we make out of it, which would be similar to overcoming our temptation to create the CO2 in the first place.

    then what happens when we find out we need that CO2 and we gone ahead and blasted it out into space?
