I think the more interesting question is how did they move the stones. I believe they may have used sound.
I believe you are referring to this link
which you posted in another thread. It claims that 150 kg stones were lifted 250 m in the air (also some horizontal motion but we'll ignore that) in about 3 minutes using 13 drums and 6 trumpets. The energy needed to lift a stone of this size comes from the formula P.E. = mgh:
P.E. = 150 kg * 9.8 m/s^2 * 250 m = 367,500 J
A horn produces about 0.3 watts and I'm guessing a drum is in the same ballpark http://en.wikipedia.org/wiki/Sound_power
19 * 0.3 W = 5.7 W total
5.7 W * 3 minutes = 5.7 W * 180 s = 1026 J.
We'd need about 358 times as many instruments and that's assuming 100% conversion efficiency, which is an unreasonable assumption considering that the instruments are 60 m away from the rock (most will go in other directions besides towards the rock) and that no mechanism has been proposed to explain how the sound energy would preferentially apply force in an upwards direction only.
I noticed the following claim:
Because he had the opinion in the beginning that he was the victim of mass-psychosis he made two films of the incident. The films showed exactly the same things that he had witnessed.
The English Society for which Dr Jarl was working confiscated the two films and declared them classified.
This "my society classified the films" argument falls into the same category as "the dog ate my homework." The homework and the films never existed.
