Can this be true?

Is this now another dream or can it be real?

I dunno (IANAPC), but the original paper was published in September 2011 and doesn't seem to have aroused much excitement amongst the scientific community.

The proposed chemical reactions and the considerations of binding energies look correct.  The thing to remember is that if something works in the lab, there’s no guarantee that it’s practicable in the real world.  The engineering problems and/or cost of implementing it on a sufficient scale may be prohibitive.

I read the article published in the Journal of Physical Chemistry this morning. The theoretical science behind the paper looks sound with respect to thermodynamics and the fast reaction rate also suggests it would be feasible. I think the part in the zmescience article about generating power is a bit far fetched although it is an exothermic reaction I think more power would be used to create the reacting chemicals(Li3N) and the cleaning of CO2 streams. I still think this looks like a promising way to reduce CO2 emissions. As Mefiante says you would need to prove it can work on large scale, the next step would be to scale up the experiment to use a few kg of reagents.

Here is the full article: https://rapidshare.com/files/1934254364/jp205499e.pdf
