New self-assembly nanotubes turn the impossible possible.
The Moiré pattern allows nanotubes to undergo a self-assembly process. Self-assembling nanostructures are a fundamental thing in nanoscale systems. That makes it possible to create extremely long nanotubes. Those nanotubes can be the fundamental materials in lightweight and strong structures, from extremely tall buildings to very strong aviation materials.
Nanoscale technology means that. The structure is planned and created at the atomic level. The nanoscale structures are like LEGOs, and they can form larger structures. Nanotube technology makes it possible. To create lightweight and strong structures. In nanotube-based nanostructures, the nanotube bundle is bound together using a graphene layer. That makes the structure strong and lightweight. Those nanotube structures make it possible to create very tall buildings.

Artist’s impression of a space elevator
"A space elevator is conceived as a cable fixed to the equator and reaching into space. A counterweight at the upper end keeps the center of mass well above geostationary orbit level. This produces enough upward centrifugal force from Earth's rotation to fully counter the downward gravity, keeping the cable upright and taut. Climbers carry cargo up and down the cable." (Wikipedia, Space elevator)

The space sling is one of the versions of the centrifugal launch systems. Or spin launchers. The idea is similar to space elevators. That benefits Earth's rotation. For transport satellites to the orbiter or even to the solar system. The idea is that the probe is connected to a satellite using a very long cable. On the other side is the counterbalance. When the system launches a satellite, the space sling slings that cable. Where the probe is connected like a sling. When the satellite is separated, the system must also separate the counterbalance that is on the other cable. Or it must roll that cable inside.
When we think about mega-projects like space elevators, we always think about the mast-shaped structure. That some kind of asteroid keeps up. By benefiting from the centripetal force. The structure can also involve a pressure statue. If the system allows the airflow inside that tower. The air pressure pushes it up. And pressure keeps it in its form.
Another way to make that tower is to use the same technology. Used in the Burj Khalifa tower in Dubai. The building requires a large area base, which could be hundreds of kilometers. If the building’s area is large enough, it can be so high that it can reach even the edge of space. The building could be the mega-pyramid that has ever been seen before.
And anyway, if we think about a kilometer-high launch tower, the rocket will launch through the low-pressure channel, which can save fuel. The rocket will be put in a launch position in the launch tube. Then the hatch at the top of the channel will open. And low pressure pulls the rocket through that channel. But those things are future visions. About systems that can revolutionize space technology.
