Vortex Dehyration System
Can crush/separate to micron size rock and concrete, can dry/powderize animal waste, and can desalinate seawater if you have hot inputs

Fins Formed on Auto Tire to Reduce Air Resistance -- Tech-On!
Weird ribbing on the inner side of the tire creates a vortex in the wheel well, ostensibly keeping air from spilling out of the wheel well and ruining the aerodynamics of the overall car body, so it's a net gain despite the increased air resistance within the wheel well.

Atmospheric Vortex Engine
A heat engine of sorts, using a captive tornado rather than a solid walled chimney. Apparently getting some light VC funding now, but this guy has been running on fumes for years. I wonder what caused the sudden investment now?

Encoding many channels on the same frequency through radio vorticity: first experimental test
New trick of adding vortex twist rather than traditional polarization to a signal to boost encoding for a single frequency. The requirement for what appears to be a directional helicoidal parabolic antenna ( does this mean the antenna needs to be a few wavelengths in depth?) means no love for mobile omnidirectional antennas though.

CAITIN-Advanced Vortical Cooling Technology
Interesting concept for a supersonic vortex refrigerator. I'm not clear how this works, since it would seem to at the least still require a circulation pump, which functionally wouldn't be all that different from a conventional compressor...

Oceans of plastic
Okay, the idea is attractive, but collecting all the microscopic trash plastic particles without killing off huge amounts of local life will be hard. Any driftnet approach will kill all animals collected by design unfortunately.

Caltech Researchers Find Schooling Fish Offer New Ideas For Wind Farming
Interesting idea for using constructive interference from VAWT wind turbine shed vortexes to boost apparent wind for other turbines in the array, much the same way as schools of fish and perhaps flocks of birds scavenge the vortexes being shed by the lead animal to reduce their own drag and increase lift. Only problem is that you have to tune the turbine array layout to the predominant wind speed and direction, so off-spec wind could potentially hurt performance. Winglets on individual rotors may be more universal. But many places have fairly predictable wind patterns, so the layout trick still has merit.
