    Chemists have shown that it is possible to use solar energy, paired with the right catalyst, to convert carbon dioxide into a raw material for making a wide range of products, including plastics and gasoline.

    Researchers at the University of California, San Diego (UCSD), recently demonstrated that light absorbed and converted into electricity by a silicon electrode can help drive a reaction that converts carbon dioxide into carbon monoxide and oxygen. Carbon monoxide is a valuable commodity chemical that is widely used to make plastics and other products, says Clifford Kubiak, professor of chemistry at UCSD. It is also a key ingredient in a process for making synthetic fuels, including syngas (a mixture largely of carbon monoxide and hydrogen), methanol, and gasoline.

    The work is part of a growing effort to find practical uses for carbon dioxide, a leading greenhouse gas, says Philip Jessop, professor of chemistry at Queen's University, in Ontario, Canada. Converting carbon dioxide into carbon monoxide is difficult to do, which Jessop says makes the UCSD work impressive and exciting.

    •  Carbon Emissions (0+ / 0-)

      I can definitely be wrong but as I read the diary and understand the process, it shifts the carbon emissions from the coal plants to the tailpipes.  Carbon will still be emitted.  What percentage of the existing carbon footprint will disappear through this process I don't know for sure but it ain't gonna be zero emissions.

      Not saying that this isn't a good thing to research and develop.  Just saying that it ain't a complete answer.  Perhaps there's no complete answer.  I don't know.

      Also, the time it takes to develop these technologies will probably not make them useful within the next decade [as the Tech Review article states] and the latest news from the climate scientists is that we don't have a decade.  We might already be past the point of no return or have as little as a couple or four years.

      I don't want to discourage people.  I just want to be realistic.
