Reading Mr Musk's "Time to settle this, - how were these built"?
with the photo of pyramid in there.
First, it came as your challenge Mr Musk,
because the very first thing I suggested was I believe a fixator,
in cubes, to build a spaceship in zero gravity. A "courtyard",
if you remember.
Then I inserted these cubes inside a rocket.
Then the issue came when the material to build these rockets in orbit
required cost effective way to send materials to orbit.
Then I suggested the space 'elevator', which did not work out.
I believe I suggested something in orbit to hold the lines as its own gravity.
But you relayed the Earth's gravitational pull is too strong for this.
There then were the 'pods' that carried metal powder into orbit,
alongside laser sintering printers for these metal powder.
Then I came up with side turbines attached to it. And eventually,
scratched the idea altogether. As it kept failing.
The things that triggered me to design the space escalator,
or the "pyramid" were few things. First, I was designing the
"Greenscreen pillars" which were long lines of cubicals.
At that time it wasn't greenscreen, it was just pillars protruding
and retracting. This was to create an ever-changing house/interior.
At will. Eventually the greenscreen was suggested digital.
And that idea, playing with sketchup, and having thinking of this
game, "tactics ogre" which is an isometric game in cubes,
alongside on youtube, "stairway to heaven" with an literal image of
stairway to heaven. Triggered me to design it, however, automated
by machines.
You can see since from the very beginning, my design in ship, pillars,
courtyard, it is all in CUBES. And so is the space escalator,
first stacked one by one, one at first, two the next, 3 on the next line,
etc. Only to be cut diagonally with a machine. Then the machine had
to follow a track, with a round, flat saw. The diagonal half a cut of
that cube would be discarded, or sent back down. But now the stability
was the issue. Hence the interlocking feature to stabilize the cube
as it drops from the side were created, incrementally lowering down
to the sides of the height. Stabilizing the structure as the slope
increases in height. When all that was designed, (I believe I was
in a competition with you, to better design from the draft I made)
which at the time, the tracks for it were going along the sidelines)
Of which I simplified the stability of it by not going against gravity,
and creating tracks only on the slope. Etc.
So don't ask the origins. It was all designed by me.
