[Terrapreta] Another promising carbon capture technique

[David Yarrow]

this is very cool.  i was just today telling doug clayton that nature's 
other principal pathway to capture carbon from the air is to convert it into 
carbonate.  a major chunk of this is making shells for exoskeletal organisms 
ranging from microbes in the sea (including coral) to mollusks and 
crustaceans and on up into bones of large animals.  a lot of carbon is 
concerting to shells of sea creatures, which then die and form sediments on 
the sea floor, which become fossilized as limestone.  i told doug to look 
out for a technology to capture carbon as carbonates.

and a few hours later, here it is, apparently.  and it's exothermic to boot.

the question now is how to commercialize this process and deploy it 
widespread.  and can it make money, as in' turn a profit?

for a green & peaceful planet,
