telescoping

Telescoping end points similar to the telescoping air plane ramp are noted in the pdf.

You could make a telescoping sheath for keys that would hide the cuts when not used, and retract when the key is pushed into the keyhole.

My understanding is that the thermal expansion is taken care of near the stations with a telescoping section.

Seems like there's probably a better way of doing this that avoids that--a telescoping down tube with four hinges, perhaps.

Does it have a built-in telescoping ladder - that could actually be quite a lot more useful than the firehose...

You forgot the laser-guided dado cutter, and the telescoping illuminated wet-dry vac with AM/FM radio.

It is impossible to look at it without an uncanny feeling of recognition, telescoping a century into the blink of an eye.

We do this only because of the type of risk telescoping you are doing.

This can be done much easier along the ground, and with the capsules already slowed right down even a 500foot long telescoping tube is feasible.

It'll be telescoping and lined with something to kill the bug.

I used to clip a telescoping pointer on the edge of my CRT.

The paper describes having a telescoping section on each end to accommodate thermal expansion, but the previous commenter is stating that it is likely this telescoping method will not be sufficient, as the variation in length of the structure will cause significant bending of the pylons themselves.

You might stack up a couple of reams, which is a lot lower than the stacks shown, and it might be possible to add some kind of collapsible/telescoping "corner plates" that would help keep the stack from shifting.

"By building a system on pylons, _where_the_tube_is_not_rigidly_fixed_at_any_point" [...] "A telescoping tube, similar to the boxy ones used to access airplanes at airports would be needed at the end stations to address the cumulative length change of the tube" So, the tube is lying loose on the pylons, and he assumes it will keep its shape while expanding.

From what I cited: "A telescoping tube, similar to the boxy ones used to access airplanes at airports would be needed at the end stations to address the cumulative length change of the tube" I guess that's because accordion-like flexible sections and carriages moving at 1000 km/h on a tiny air cushion don't go well together, or because such sections, being a lot leakier then welds, would let too much air in.

Except for that "reasonable restrictions" are rather like abortion regulations; they're obviously driven by ideologues with no technical expertise, specifically to make the exercise of a right more burdensome, like "waiting periods" for existing gun owners, restricting or permitting models by name, or regulating cosmetic features (oh no, a scary telescoping stock!).
