Why can't we make a space elevator using Quantum Levitation?

In summary, the idea of creating a space elevator using separate rings that are stacked and quantum locked over each other is being discussed. This would allow for the ladder to freely move and change shape while still remaining intact. The transportation of objects would be done by placing them in a magnetic capsule and using superconductivity to move them up the ladder. However, there are concerns about the weight and stability of such a structure. The terms "quantum locked" and "quantum levitation" are being used to describe the technology, and further research and understanding is needed to determine the potential of using this technology for space elevators.

Why can't we make a space elevator out of separate rings that are stacked over each other through Quantum Levitation?
You know, have hollow rings that are quantum locked over each other, like in this video That way, the ladder freely moves around and changes shape, but would still be "intact". Transporting something would be done by putting it in a magnetic capsule, and then using super conductivity to get it all the way up the ladder? I have zero experience in anything space so bear with me..

Look how easily you can remove the superconductor from the magnet. I don't think an elevator would hold together.

What does "quantum locked" and "quantum levitation" mean? And if you mean magnetic levitation, possibly involving the Meissner effect, what makes you think this supports an arbitrary amount of weight?

Hello! Found this thread through interest and some research into the matter.

Isn't it possible to increase the energy output into magnets, and thus you would "push"/"lift" the object upwards? (I personally have no idea, this is merely a hypothetical theory)

There is distance between the superconducting object and the magnetic platform after all... so it is a question of proportions, is it not? How big would you have to build a magnetic platform to be capable of "lifting" something out into space, using this technology? Furthermore, is the superconducting object "weightless" in the state of quantum trapping/locking?

If, for instance, we say that we have a superconducting object hovering above 1 square meters of a magnetic platform, and there's 100 square meters underground/under a door/surface/gate. Would the magnetic force be greater if one would open the gate 1 square meter? Or 2 square meters? Would it cause the superconducting object to rise, or would it stay "locked" in position?

EDIT: I would suggest checking out more information about the matter on TEDTalks with Boaz Almog.

1. Why can't we make a space elevator using Quantum Levitation?

The concept of a space elevator is still in its early stages and there are many challenges that need to be overcome before it can become a reality. Quantum levitation, while a promising technology, has certain limitations that make it unsuitable for a space elevator.

2. What are the limitations of Quantum Levitation for a space elevator?

One major limitation is that quantum levitation relies on superconducting materials, which require extremely low temperatures to function. These temperatures cannot be maintained in the Earth's atmosphere, let alone in space where there is no air to dissipate heat. This makes it impractical for a space elevator, which would need to operate at room temperature.

3. Can't we just use a vacuum chamber to maintain the low temperatures required for quantum levitation?

While a vacuum chamber can help maintain low temperatures, it would be extremely difficult and expensive to build and maintain a vacuum chamber that is several kilometers long (the estimated length of a space elevator). Additionally, the vacuum would need to be maintained in the entire length of the elevator, which is not feasible.

4. Are there any other challenges to using quantum levitation for a space elevator?

Yes, there are several other challenges such as the need for a constant power source to maintain the superconducting state, the possibility of materials degrading over time, and the need for a strong and stable base for the elevator to rest on. These challenges make it currently impossible to use quantum levitation for a space elevator.

5. Is there any research being done to overcome these challenges and make a space elevator using quantum levitation a reality?

Yes, there is ongoing research and experimentation being conducted to address these challenges and find alternative solutions. However, it is a complex and long-term process, and it may still be many years before a functioning space elevator can be built using quantum levitation technology.
