The guy is a mechanical genius! Too bad he didn't get an engineering education, instead of training in carpentry. (OTOH, his carpentry skills obviously serve him well in his present endeavours...)
Once you've seen it, his technique of "walking" a stone using two fulcrums is obvious. (...once you've seen it, that is...) IIRC, he's moving up to 19,600 lbs stones -- so far...
The movie I got a big kick from was seeing him effortlessly roll that 300-lb square-section counterweight along the top of the big stone using his "round road" (actually a sinusoidal track...)
If he doesn't have the right answers as to how the pyramids,etc. were built, he certainly has workable answers!
Thanks for the link!!
This might be old to you, but a few months back I saw a show on History Channel. It showed how the Egyptians may have used kites to move their blocks and erect the oblisks at such great distances. The eventual conclusion was that a similar principle could have been used on the megaliths.
All one needs is a few people to keep the kites from running wild and enough rope with a support system to place the blocks with precision.
