The device supposedly produces a repulsion beam that works against matter. According to reports, the Russian experimenter produced a beam that repelled objects hundreds of meters away.
Unfortunately, mainstream physics views these experiments, and their underlying theory as pure bunk.
That being said, did Boeing consult with top physics departments in the country to examine the reliability of Podkletnov's claims? I'd hate to think that the Boeing managers (whose physics level probably doesn't rise above Resnick and Halliday) are being taken in by charletans, speculators in high temperature superconductors, and their camp followers.
