Interesting. 

The scale would have to be enormous to absorb a billion tons of carbon dioxide every year.

How reactive is the end product?  Does it dissolve in water?

Wouldn't a timber building be easier?

Perhaps we should start building more log cabins and log houses...  just to maximize the use of timber.  Except that we can barely sustain our timber needs as it is.

Good point, but timber has a habit of rotting, returning the embodied carbon to the atmosphere...

We can treat the wood with toxic petroleum products  [^]

Very funny!

Nice idea, but I would be very interested to see how much energy is actually put in!

Surely it would be better (and perhaps Jim Bob could help here) to pump it into depleted hydrocarbon reservoir rocks to enhance oil/ gas recovery and lock it away back underground.  A lot of the infrastructure/ technology is already there.

they did make an effective carbon cleaner system that took in more co2 then produced and though of putting the carbon liquid  solution in dryed up oil deposits to make more oil or shooting co2 frozen missiles to the bottom of the ocean
