I'll tell you, we'd prevent the buildup of CO2 in the www.transitofvenus.org atmosphere without having to completely restructure our society. Now I'm not sayin' I wouldn't mind a bit of viagra sales drug restructuring, but it certainly couldn't hurt to try to convert CO2 to hydrocarbons.
And researchers at the University of Messina in Italy are trying. Exposing CO2 to a platinum-paladium coated nanotubes and the protons from water split by the sun in the presence of a titanium photocatylst can produce five and www.fluestertuete.de six carbon long hydrocarbons. These can then be efficiently converted into gasoline.
The process is certainly far to expensive to implement right now, but researchers are confident that a viable version could be ready to produce hydrocarbons industrially "within a decade."
