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.

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.
