Maybe, but it rather seems to look at the research being done in this area if you mean the u-tube video. The other link has a reply in it the says that sledges have been used.
What do you say about the Florida guy with his Coral castle? Anything on him?
Here is an idea that seems more likely than that the stones of the pyramids were cut and carried into place. (And much more likely than they were levitated by sound!) They were cast like concrete.
Can it be scaled up? I'm thinking no. I believe the forces would scale as the surface area of the object being levitated whereas the weight would scale as the volume. It's the old square versus cube problem.
How do you find out particle size distribution in a powder - be it cement or pharmaceutical tablet. The powder is sprinkled on a table and the powder particles are levitated ultrasonically. Depending on weight / gravitational force and ultrasonic levitation force- you can determine particle distribution. I have seen this kind of an equipment.
