Do you have a rough idea of how much such a cylinder weights? It has a volume of about 3200 cubic meters. Soil has a density of somewhere between 2 and 3.3 metric tons per cubic meter depending on the type of soil. So you’re talking about handling and lifting blocks of anywhere between 6 000 and 10 000 tons apiece. And that still assumes that the cylinder is made of solid rock that doesn’t break apart.
