When I rule the world – part 3

And finally! Let’s tackle the BIG ONE – excess CO2 in our atmosphere

Yet again, many more intelligent minds than mine have been exploring this one. And yet again, that’s no reason why my ha’penn’orth shouldn’t be heard.

This goes back to the dark ages when I was doing Chemistry at school. You know those days when we were allowed to have bunsen burners on, roll mercury down the lab bench and make pongs and flames (Health & Safety eat your heart out!)

One of the things I recall is that we often used to do experiments which resulted in the production of a gas. Which we would frequently bubble through some liquid or another. If the liquid went cloudy, then it demonstrated that it was CO2.

So, am I right in thinking that the CO2 we produced was bound the whatever liquid it was (senior moment, memory failing).

So. Why can’t we bind the CO2 in the atmosphere through whatever liquid it was to remove it from the atmosphere?

My first thought was that we could bounce all those scientists out of Cern and use the miles of tunnels deep underground to suck air into. But that would require engines and effort and energy. Counter productive, huh?

So then I thought why don’t we use the air turbines being used to generate electricity? No extra energy required, hey are designed to draw air over their blades.

So the idea is this (and a picture would be so much more useful a this stage, but I’ll do my best in words)

You have your wind turbine with a reservoir or liquid and the air drawn over the blades is sucked through the liquid (somehow!) until it becomes saturated or super-saturated. At which point it is replaced with fresh liquid and so on.

Now a refinement to this thought process (if you can call it a thought process!) is that the wind turbines should be placed over caves, mines or land of a suitable geology so that if the super-saturated liquid is dripped over it, it creates stalactites or stalagmites of incomparable beauty and magnificence. And the CO2 is gone!

Hmm. What do you think? What have I missed?

  1. Only meeeee ! And a sensible answer ! (sorry)

    The liquid is called lime water – dilute calcium hydroxide and when you bubble CO2 you get a precipitate of Calcium Carbonate aka chalk…

    Ca(OH)2 + CO2 -> CaCO3 + H2O

    The problem is how do you get the lime water?

    Normally by heating Calcium Carbonate to drive off the CO2 to form Calcium Oxide (aka quicklime) which you then react with water to form slaked lime …..

    Think you have spotted the flaw!

    Phynbarr here – So get creative!

  2. Please see the following;

    Where this has been observed in nature.

    Personally, I don’t believe we need to decrease CO2 in the atmosphere. I think it’s hocum, and that there’s something else afoot about which we have no idea. The CO2 levels, along with O levels in prehistoric times were much, much, much greater than they are now, and the dinosaurs seemed to manage alright. They did much better than we ever will in terms of timescales and living on this planet anyway. I think reduced biodiversity due to farming/fishing/general idiocy is of much greater concern. I would gladly increase CO2 levels a lot higher if it meant I could save the Tiger from extinction. Double CO2 levels to help the fish. Triple it to save the forests.

    To be honest (depressing comment following) I think that we’re doomed regardless of what we do. You can see it everywhere we look, we are simply consuming too much of the wrong resources. We need to look at husbandry of the earth as a race, or that’s it. And as we won’t change quick enough; We’re done for.
