I agree with Nigel.

The major breakthrough, if it works, is Gordon`s idea of using the lever principle to `row` the stones across the landscape.

If you can do that, with comparative ease and a far fewer workforce than other attempts, then that should be demonstrated first, but you`d have to do it with the 40 ton stone.

The trilithon project is a far bigger task, with all of the details far from being worked out yet. While we`re working on the theory of erecting the stones, we should also be thinking about a basic demonstration of simply moving large stones over a distance.
