Transforming carbon dioxide into industrial fuels

• One day in the not-too-distant future, the gases coming from power plants and heavy industry, rather than spewing into the atmosphere, could be captured and chemically transformed from greenhouse gases like carbon dioxide into industrial fuels or chemicals thanks to a new system that can use renewable electricity to reduce carbon dioxide into carbon monoxide -- a key commodity used in a number of industrial processes.
• The most promising idea may be to connect these devices with coal-fired power plants or other industry that produces a lot of CO2
