Supposedly turning atmospheric CO2 into coal is in the realm of possibility. One article I read said that it could be put back into the ground, however it could also be burned for energy, along with the byproducts produced from it.
A different article I read earlier today said something different from this article; that researchers actually made coal flakes from CO2 at room temperature. |
What would the energy requirement be,per unit of energy,to take a diffuse feedstock,and convert to to a condensed,compact fuel?
It seems to defy (energy and economics wise) the second law of thermodynamics.
