Now this is really interesting, Vacuum as an energy source. Just think of not only the application of it here on Earth, but also for space travel. 
Don't know if this is bunk or not but here's the papers on it
Professor Turtur's basic explanation of his theory here
Professor Turtur's paper here
Here are his publications, he does look legit and not a whack job.
