Carbon sucker

This could solve few problems

To me, this sounds a lot like an advertisement for this guy's business, rather than a viable scientific proposal.  
I would like to have seen some details of the process:

* How much energy does the process require?  
* Where, exactly, is that energy coming from?  ("Renewable electricity" is pretty vague.) 

These 2 points cannot be emphasized enough; I have read that if the United States were to capture every single photon of light from the Sun (hitting US territory) and convert such into renewable energy such would only meet half of the country's energy needs.
