Greenhouse to Concrete?
A new technology has been developed and a California based company says it can turn CO2 into cement by simply bubbling the waste gas from a gas fired power station through sea water. You can read about it in Scientific American in the online version. It seems to me to be an emminently sensible way to go with this gas, after all, we need to meet the growing demand for electricity, yet the options for producing it are almost all polluting in some way. And according to Greenpeace we only have enough nuclear fuel for another 75 years.
Mind you we ran out of petroleum around 1940 if you believe the sort of "estimates" they usually run with.
It seems to me sensible to explore recapturing CO2 and converting it to cement. We need cement for the housing and structures our out of control populace demand and currently cement production requires the burning of limestone in order to produce the quick lime and slaked lime that goes into the raw cement mix. And that produces CO2! Now turning the CO2 into cement means no only less "Carbon Footprint" but it also means that we tie up the nasty stuff in a permanent bond that will keep it out of circulation.
Let's hope it works and, more importantly, that the bureaucrats and political a*s*h*l*s that usually delay or scupper any sensible solution don't get in the way this time.
