Re: A new type of material for building space ships and space elevators! ¶
Even graphene. A few miles of it pushing into the same spot isn't clever, so will need to spread that force over a wide surface area. To avoid it toppling, this is also likely to require to be set deep into the ground. Really deep, at least 1/3 it's total length. To resist torsional sway, it'll need to sculpted to allow the wind to pass - especially as the wind at different heights can be different directions. It's also going to require to be rediculously thick at the base, tapering thinner upper - adding to total weight.
Resonance of a structure that long alone would be problematic and represent a engineering problem I'd not like ot solve. Earthquakes would be almost impossible to counter.
As a material graphene has many potential uses, and can enhance multiple existing technologies - but I don't see it buliding a space elevator any time soon - building something that long, and keeping it straight is too much of a headache.
