© Surya Prakash / University of Southern California There have been quite a few ideas about what to do with all of that extra carbon dioxide in the atmosphere that is fueling climate change. Carbon capture and storage schemes have been around for years like this one from Harvard that uses plain old baking soda as well as technologies to take the CO2 and make something useful out of it.

Some technologies have created things like carbon nanofibers from the gas or even diesel fuel. A new breakthrough from scientists at the University of Southern California takes CO2 and turns it directly into methanol (its combustible cousin), which can be used in fuel cells, as a clean-burning fuel for internal combustion engines or to make things that normally require petrochemicals in their manufacturing.

USC says , "The researchers bubbled air through an aqueous solution of pentaethylenehexamine (or PEHA), adding a […]
