There was an article about something that sounds similar in Popular Science last year. I found a copy of the article here:

They claim the process is efficient enough that the fuel generated by it can be used to power the plasma torch with plenty left over.

I hope it's self-sustaining, because it wouldn't be nearly as useful if they need separate electrical power from coal to run the thing. There are already other processes to convert coal to crude oil, this plasma machine just adds an extra step.
