Diamond Nanothreads Could Support Space Elevator

Diamonds burn when heated and an adequate supply of oxygen is available. I imagine a single diamond thread in the atmosphere might be vulnerable if heated given a relatively large surface area relative to the cross section.
What about Q-Carbon that is stronger than diamond?

Interesting - thanks - a new allotrope of carbon that's apparently ferromagnetic. It would be interesting to know what its Curie point is. I have no idea whether it burns more or less easily than diamond although I would suspect less easily if its bonds are inherently stronger.
Lunar elevators are possible with current tech.
There are lots of interesting materials being looked at.
I was reading something about stainless magnesium recently.. In other news, a blend of "hafnium, nitrogen, and carbon (HfN0.38C0.51) would have a melting point of 4,400 kelvin = 7,460 F."
I wonder about Borazon's usefulness: https://en.wikipedia.org/wiki/Borazon
Borazon is used in industrial applications to shape tools, as it can withstand temperatures greater than 2000 °C (3632 °F), much higher than that of a pure diamond at 871 °C (1600 °F)
Then, too...I suspect that something as un-interesting as this pipe bending machine may wind up being of more use to space than nanotubes:

This might make something like larger pressure-feds more possible.

First question is would there be a load placed on the cables of the space elevator seeing as how the elevator itself would be in orbit?
Secondly the cable itself wouldn't be long lengths of cable but shorter lengths connected together maybe 1,000 feet then a connector and then another 1,000 feet. Shorter cabling would actually create a stronger tensile capacity for the entire cable itself.

Oh boy.
LOL. Sounds like my wife after the dog shit on the floor.
Here is what a drag line cable looks like.

The Space Elevator Cabling wouldn't be simple twisting of cables. The Space Elevator Cabling would need to have electrical and grounding cables part of the main cable as well.
You would have to have some type of system that would reduce the force on each cable as the elevator in orbit was basically pulled the Earth as the Earth made its daily rotation. Or will there be thrusters on the space elevator to help maintain its orbit?

If you look at the drag line in the link above the same type of system would be used where pulleys would tighten a section of cabling to allow another section of cabling to relax to reduce wear and tear.
The space Elevator is like fishing for a 25 pound walleye. Using just one strand of fishing line causes all of the exertion from fighting the fish to be place on the same line. But if you have two or three smaller strands the exertion is spread out over all three fishing lines that reduces the stress placed on a single strand of fishing line.
You also have to think about the cable being in space as well. Metals contain small amounts of water that cause corrosion. In space the water would freeze cause the metal cable to become extremely brittle and break.

Diamonds burn when in the presence of pure oxygen. The atmosphere is not comprised of pure oxygen nor is there going to be an amount of heat present in the temperature range of 3,480 degrees to cause the diamond to burn.
The diamond nanothread cable could be used to secure the space elevator to the surface of Earth but at some point would be connected to normal cabling like the cable linked above once the metal cabling was below the height of water freezing in the atmosphere. The only method of keeping the water from freezing would be to have a strand of cabling that was heated running through the main cable to keep the water in the metal of the cable from freezing which would allow the metal cabling to reach further to the space elevator where the diamond nanothread cable would only be used for orbital connections.

Semantics and general catch phrases is not how a complete and sensible thought is conveyed either.
Atomic oxygen is still going to attack anything that extends through our atmosphere--not to mention icing loads, convection from the ITCZ, lightning strikes--maybe even grounding some of the global electrical circuit.
A lunar elevator has none of those risks, is do-able with current levels of tech--and has no risk to Earth-orbiting satellites.
Learn the ropes there--before you deploy here.
LDEF proved that objects do wear in space.
