There had always existed a bottleneck which affected my concepts, as well as, all others. It was the need to deliver 1 stone every 3 minutes, for a 20 year build. I struggled with it for years.
This newer concept blows that right out of the water. Suddenly, that part is minor when compared to quarrying the stones, and delivering them to the base.
12 lifts, delivering 2 stones every 2-3 minutes. That now becomes 12 - 24 stones 2-3 minute, depending on the build height. Wow. Maybe it never took 20 years to build a Pyramid?
