the actual rotating valve (circular driving wheel by hand, i've drawn earlier),

that is metaphorical. It need not actually be attached outside

the cube. Inner mechanisms that lock each other and presses

them together is the way, minding however the pressure

of the water. Alongside designs that is meant to interlock them

by their crevice/lining.

 

relayers, please do not relay Sean Kernan's writings to me.

 

do understand what this guy's done.

 

 

 

you would think, the origins. the people who started all this

 

would at least be caught.

 

 

 

 

They must be.

 

 

then mr Musk, that 3000 meters must be calculated of stability.

if a pillar, cylindrical, to this incredible height,

 

what material? what thickness, what shape?

 

and it may end up,

 

 

the cylindrical slice above larger cylindrical.

this design may need to be inside that hollow space.

 

so same design, within the cube design.

 

 

but of different material.

and different method of construction.

 

 

so it may require a lot of space.

 

 

but not as much as a city. xD

 

that would be almost failproof way i believe.......
