[1908.09339] The Spaceline: a practical space elevator alternative achievable with current technology
Oddball lunar space elevator design, optimizing for upper tether length to top out at GEO height. They suggest a hybrid tether design, with constant width tape from both ends up to a certain point, then a center section that gets wider.

Olds Elevator - Vertical Conveyor Technology: new Solutions in Material Handling
So this is the inverse of an achimedes screw, where the auger/screw is stationary, and the casing is turned, which makes some things easier mechanically

Okay, this seems like an actual improvement over Amazon's Kiva whole shelf moving UGV's. Using the drones as both UGV's carrying single trays as well as elevator pickers to pull from dense/high tray stacks means you can multiplex tray picking from the stacks, rather than the typical separate elevator picker bot permanently mounted on the shelves.

The implication is a mars (Deimos) tether anchored off equator (13 degrees) has sufficient catenary curve to passively avoid phobos. Notably this is for a zip line down to the surface.

The Great Reduction of a Carbon Nanotube’s Mechanical Performance by a Few Topol...
Single atom displacement drops carbon nanotubes to 40GPa, multiple defects make it much worse. So unless you have a perfect set of tubes/fibers, there will be no earth space elevator using CNT's.

KONE UltraRope - The benchmark in high-rise technology and innovation
New carbon fiber elevator cables with a high friction coating. While they do cut down on weight/power for normal elevators, they really shine in the super height elevator class (500m+).

Odd vertical farming layout hardware. Basically uses a continuous chain loop/ferris wheel to carry troughs up a vertical distance. So at first glance, probably not hydroponic compatible. Also, seems to focus on leafy plants, and the troughs may be shaded for half a transit on the loop. Still interesting. Apparently in commercial use in Singapore.

The Future of Space Exploration on Display in NYC - American Museum of Natural History - Popular Mechanics
Kinda strange looking exhibit. Is this supposed to be the surface anchor, because it sure doesn't look like normal climbers to me? Maybe a lunar polar station anchor, since it's tilted?

Interesting concept for lunar sample return. But the architecture (EML1 centered lunar space elevator) has interesting implications for other purposes. Since it hangs "down" from L1 to earth, it's about halfway between GEO and L1. This means a notional SPS hardware delivery system that might take advantage of a two stage delivery (impulsive tug to L1, SEP tug from L1 to GEO) can be changed to not needing a SEP tug (drop off at the CW and do a small burn when approaching GEO), and possibly integrate with the impulsive stage ops. Say, burn to L1, grab and ride the tether then let go, do a light burn to place payload at GEO, then burn for aerobraking drop to LEO. This cuts deltaV down a fair bit. But, this requires a solid lunar surface anchor as you are now pulling up on the elevator every time you try to drop a load to GEO. I suppose you plant the anchor for the balanced cable, then use bulldozers to keep loading regolith on top of the anchor to weigh it down.

Now you and 79 of your closest friends can ride the same elevator! (Interesting parallel to the jet business, now going wide, which means the next big step is a large capacity double deck elevator...)

Oh this hurts my head. Basically, exploiting non traditional phenomena could allow a space elevator using unpowered climbers, the achilles heel of traditional linear space elevators.
