How do you know that they haven't been in the oil sludge business? They haven't made public much of anything that they are up to. You also can't believe that they're getting rich and living off investors from the dilution that they have done so far. If the dilution was in the many billions with a bunch of nonsense pump PR's I wouldn't invest a dime in it. If that starts happening you can bet that I'll bail, but I'm not in the least bit worried about that occurring.
