OT: Slinky Question

Only if you match the escalator speed dynamically to the slinky, and dynamically adjust the stair tread depth to stop the slinky slowly edging further out or in and stalling, plus add air jets each side to stop it bumping into side walls. So... its possible.

What happens when the escalator reaches the end???

Just make the slinky large enough in diameter, and large enough in coil count to make the standard escalator tread "just right" in size and depth. That way, the lateral movement wont matter either. It will always fall onto the next tread down.

Hmm. What about an actively steered slinky? A small plate at the end, with a weight that can be moved around it.

A Phased array slinky?

A remotely controlled, gyro stabilized, rad hard, rugged slinky.

What will they think of next?

In any event, slinky technology will have to be stretched beyond its present limits and such issues addressed one step at a time.

Certainly here on the London Underground they make the escalators long enough that they last all day. They do a fast rewind at night so they are all loaded up again at the right end of the escalator. I haven't done the maths to work out how much track they need to store for a day's operation, but it must be quite a lot. They must have really big pits under the escalators for storage.

I have never been on an escalator that reached the end while it was still supposed to be working, but I imagine it must happen sometimes, like when there are delays on the rail network. I suppose there must be some kind of stop, otherwise the loose end would pop out of the track, and it would be really hard to thread back in again.

No. But this newsgroup thread will!
