So as an augmentation to other sources of lift, it seems like a credible concept to me.

That's where my thoughts were going as I read this great thread, I was also thinking about many or a number at least of smaller balloons, another poster mentioned attaching wooden frames to blocks then rolling them I'm sure I've seen this method on ytube, tbh they're all good calls, lol!

One thing about the Egyptians is their irrigation and flood control knowledge, many hundreds or even thousands of years of manipulating water like that will give a civilisation the power to move or lift heavy objects.
