Renewable Energy – What About "Micro" Solutions?

Jan-Gerhard Hemming, a reader from Sweden, writes to suggest an industrial carbon cycle paralleling photosynthesis, recycling CO2 from flue gases – eventually from the air itself – converting it chemically or electrochemically to methanol and benign byproducts.

I’m always fascinated by ideas for processing CO2 at the source point of the emissions. But personally, I believe that there are “macro” solutions that can and will obsolete fossil fuels, if we can amass the political will to get there. Some of these are discussed in the reports, e.g., solar thermal and hydrokinetics. I hate to sounds pessimistic, but to me, it sounds more-less impossible to deploy millions of flue adapters, etc.
