Any mechanical engineers here? Why can't we make an elevator to space. We built the Burj Khalifa (tall building) and we also built really good rocketships.

Why can't we build an elevator to space?

What if we used steel rebar reinforced with concrete?

a space elevator is like a thousand burj khalifas anon
give it time

why do you think ideas from your sci-fi books are feasible? There will never be a space elevator and space exploration is a cult

Sci Fi is just /sci/ + fi

If we can engineer the technology we should be able to build it.

I swear to god /sci/ is becoming a shittier board with each passing day.

Unironically get off of this board.

In short, we’re closer than people think; the main problem is stranding together a large number of CNTs into a tether and ensuring high tensile strength. Once those issues are sorted out, we’re pretty much skyward bound.

Dangerously Based.

Are CNT used in any material engineering applications or is it still just in R&D?

Because to make an elevator you need an upper floor to reach but soo far we don't have any building tall enough, so we can't make the elevator yet.

Arthur said you can build a tall structure beyond the material limits by shooting a stream of high speed liquid upstream. This would straighten the structure like a hose filled with pressurized water

Same idea for building a ring around the earth you can use to speed up spaceships to escape velocity

with existing materials we could build a space elevator on the moon

as far as i am aware CNTs currently cannot be produced with their theoretical capabilities, as in their actual tensile strength is a lot lower than would be needed for a space elevator. also the longedt CNT ever produced is like a meter long

Image the space elevator whipping a large part of earth as it falls down.

in height, but it works a little differently because it doesn't need to support it's own weight under compression which is impossible past a certain (low) height, it just needs to stay together under tension which is theoretically doable but practically infeasible.

tethers are more realistic until we master material sciences and fabrication of their products
