One of the many projects funded by our DOE on the practical sequestration and use of CO2 generated by industrial coal processes.
An excerpt:
"Scientists at Sandia National Laboratories in New Mexico are exploring the idea of using concentrated solar energy to turn CO2 into fuel. The Sunshine to Petrol project is testing a prototype device called the Counter Rotating Ring Receiver Reactor Recuperator (called CR5 for short) which turns CO2 into carbon monoxide which could then form part of a liquid fuel."
As we've been saying: There are several ways you can use CO2 to make more fuel. It should be seen as a resource, not a pollutant, and therefore a valuable by-product of coal-fired power plants, and coal-to-liquid conversion processes.
