Sorry mr Musk,

 

but the draw back on this is,

 

it regresses back to the original method of the space escalator.

 

which is building the height of the slope and dropping it down.

 

 

So four slopes comes first before the middle. Which would

need to be calculated.

 

wait i'll think of something...

 

 

 

If it's a slope, it's fixated on that specific angle.

So it can't adjust to the height of the cube/cylinder as it move up.

 

But.

 

If the machine can climb up cubes. (Like stairs) instead of a slope,

 

it can simply add another cube on top of the existing one,

 

in order to meet the incrementally increasing needs of the cube/cylinder

in slices.

 

 

Which isn't that complicated a machine by the way,

 

there are already stair-climbing machines.

 

But if to make tracks on the cubes it would be safer, and

can carry another cube following.

 

 

And at the *End of all of it, after the height is built, one

can turn the stairs into a slope, by attaching half a cube cut diagonally.
