Bring on the space elevators.

Love this guys videos, always interesting and well written.

Was anyone else bothered by how this just jumped from the tallest existing building to space elevator?

The boys are building a .. ladder to heaven.

This is a guy pretty much just reading wikipedia articles out loud.

Just don't stare too long at the sunset, guys.

Just about everyone's speaking English now (thanks to me and my army) so God clearly has given up in that regard.>> ^honkeytonk73:

NO DONT BUILD IT!!!! Don't you remember what happened after the Tower of BabylonBabel was built? God got real pissed off and made everyone in the world speak different languages. Just imagine what sort of punishment he'll dish with the ultimate of building height offenses!

Quite true. So potentially we are all forsaken and destined for hellfire. Oh well. PARTY ON DUDES!!! WOOHOO!

Sift of the week!

Just realized, he never answered the question.

He said how high we have built so far, and that we could now build a space elevator on the moon out of kevlar, and that we cannot now build one on Earth. I was looking for the answer to the highest thing we now have the technology to build, should we choose to do so.

Yeah, call me a nerd but i was actually wanting to hear a hypothesis...

But now i think about it it's probably a 'how long is a length of string' argument. The tower has to be as long as it's cumulative weight based on gravity at different lengths from sea level. It's weight depends on the materials used and the structures at different points (base, flexible joints, etc)

Every different design for a space elevator probably has a different length and weight?

However i would be interested in how the forces / torque shape up on such a structure.
e.g. G at both ends, stresses at mid point pulling in both directions, flex, wind shear, torque, harmonics. Is it better at the equator than anywhere else?
