Falcon's Wing and a Prayer

A space elevator is a so far fictitious type of planet-to-space transportation. The main element is a tether anchored to the surface and extending into space. The design would allow vehicles to travel along the cable from the surface of the Earth directly past orbit, without relying on fossil fuels in Rockets.

Unfortunately, there is no natural material known to man that can support its own way for tens of thousands of kilometers between its anchor point and the station on top. 

The material required must have a weight low enough but a strengh high enough to withstand the tension of the massive cable.

Now, spider silk has a tensile strength of roughly 1.3 GPa. The tensile strength of steel is a bit higher—e.g. 1.65 GPa, but spider silk has a much lesser density material, sofor equal weight spider silk is five times stronger than steel.

Unfortunately, it would take hundreds, if not thousands of years to farm enough spider silk in mass to make a single cable.

But fortunately, Professor Randy Lewis of genetics at Utah State University has used genetic editing to develop a goat infused with spider DNA whose milk contains the same proteins as spider silk.

Also, when spiders are fed graphene infused water their silk gets even stronger.

With the resulting super thread, machines can be produced to spin these threads into interwoven cables reinforced via three-dimensional diamond tessellation with hollow pockets filled with lighter-than-air gases of varying pressures depending on the altitude to improve diameter without adding weight.
