There is an annual International Space Elevator Consortium (ISEC) where engineers, scientists, and entrepreneurs got together to talk about the possibility of having a space elevator.
The previous conferences almost always talked about the space elevator itself, how they can create it, why they need to, and everything else that they need to know.
However, this time, a first in all the ISECs, and all over the world, that a whole day was dedicated to talking about the strength properties of carbon nanotubes (CNTs). One scientist said,
“If we could learn to make materials based on diamond nanothreads or on carbon nanotubes perfect enough and long enough, science tells us they almost certainly have the strength necessary for a space elevator,”
The first day talked about the strength of the material and how it will be a game-changer in the space elevator scene.
Some are against the thought of creating a space elevator, they say that it will cost too much, but a study actually addresses that and claimed that having a space elevator can lessen the cost of transporting loads from Earth to space to up to 90%. The current price to which we transport load to space is $25,000 per kilogram and a space elevator can bring it down to only $220 per kilogram.
So the case is that even if it costs too much, the big dip in the cost of transport will be economical in the long run.
