I only know what I read in the wiki piece, but they mentioned some version of that. I imagine goat teats transformed into web-slingers, but apparently the field is hot enough everyone is keeping their research under wraps...and we're still only talking maybe one order of magnitude stronger than steel. Carbon fibers are a perennial favorite among beanstalk proponents as well, but I know arguably less about that material.

I heard this and am saddened by it.

Sorry, but I'm just blown away. Too cool

They won't, not for a long time. They don't need to and it would only make it more difficult to do what Elon made SpaceX for in the first place - moving to Mars.

This will be interesting.
