LOL...so your plan is to keep pouring the milk as fast as you can while trying to engineer a way to suck some milk out of the bowl? Genius. Seriously.
I get the idea of removing CO2. Great idea. There's nothing out there that has the capability of doing anything meaningful in any time frame that will matter. The task at hand is to stabilize what's there now. We can NOT keep pouring CO2 into the air in the hopes that we'll develop some magic bullet that will save us. The technology exists RIGHT NOW to stabilize CO2 levels and lower the amount we're pumping into the air. The only thing lacking is the political will to deploy it. That's due - in part - to people like you who pretend there's no problem.
What's interesting about all of this is that you seem to now be on board in admitting there is a problem. I don't think you've said one time in this thread that "the beach is still there". Progress.
Please see the link posted earlier about someone who has developed your magic bullet. Page 6 or 7 thereabouts.
