NTS X-Wind
Hrm, now this is an interesting oddball power generator setup. Like a kite pulled carousel setup, but removing the need for a central rotor disk to mount the individual kites. With each kite anchored by a suitably heavy train car (that can't be tipped over by kite traction), and probably dumping power to third rail pickups, you can also optimize the track orientation for prevalent winds. The not so good part is the cornering at reduced speeds at the ends of the racetrack loop. I suppose if you had the third rail well anchored, that could provide the resistance to flipping, sorta like roller coaster rails...

Taking urban transport to the NXT level – a new concept from Scania | Scania Group
They had a the interesting idea of moving from a skateboard underbody chassis for an electric vehicle, to dual independent axle modules that resembles those hoverboard toys. Not clear if the modular body houses the main battery pack or not.

InterRegs: Regulation No. 138-01 | ECE - United Nations
European rules for electric vehicles emitting some kind of noise to reveal their presence. There are some rules regarding certain sound requirements including being suitable for increasing/decreasing based on vehicle speed. Guess you can't just stick any old jingle in an EV for the whirring sound...

Rocket recycling – catching rocket stages after launch
Huh, catching a winged first stage booster rocket by the nose, air towing to a landing site, then releasing it again so it can glide to land. Avoids boost-back for recovery (more fuel for main flight), doesn't require a landing site forward in the ground track for the booster either. Catch-and-release, like a big mouth billy bass...

iBorderCtrl? No! |
So the EU is considering a highly invasive border control scheme for Schengen access, likely resulting in an app visitors need to download to their phone. Also an "AI" interview, using the high quality of phone camera to monitor facial flushing/bloodflow/heartbeat detection to do some lie detection during the "interview" with the avatar.

Aster Thermoacoustics
Interesting work on both thermoacoustic heat sources and matched bidirectional turbines for electrical power generation. Thermoacoustic electrical generators previously used linear alternators, but those prefer faster cycles, which is opposite what the thermoacoustic wants (parts sizing goes up unfavorably when scaling), and slower long stroke linear alternators also have issues (long piston stroke, sealing issues). Using a rectifying bidirectional turbine may be a convenient workaround.

Exotec Solutions
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.
