Science brings us many wonderful things (honestly if you enjoy the benefits of the modern era, go out and hug a scientist). One of humanities age old desires is the ability to convert something invaluable, or a nuisance, into something desirable. The old midas touch if you will. Recently some scientist stumbled onto the process of converting CO2, a primary culprit of anthropogenic climate change, into alcohol… though not the kind you drink, the kind that humanity could use as fuel.
Producing fuel from CO2 is huge because it lets us take a nuisance compound, and converts it into a productive one. This was accomplished by scientists at Oak Ridge National Laboratory in Tennessee by using common materials (copper and carbon), but arranging them with nanotechnology. The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, such as ethanol. They figured they would go from CO2 to methanol, and then work out the logistics of going from methanol to ethanol, when they realized the first step in their process managed to do it all by itself. Science for the win!
