Media - News - UK team trials new ultra-endurance air vehicle - University of the Highlands and Islands
Similar to Slocum gliders, but use buoyancy in air. But considering the medium, won't you need bigger wings? I seem to remember a passenger craft concept that was similar, with a catamaran body, a large wing, and a centered over-wing engine cluster, called GravityPlane.

OSA | Evaluation of 3D printed optofluidic smart glass prototypes
So if you fill a plastic clear retroreflector with the same index of refraction liquid, the whole thing becomes clear instead of operating as a retroreflector, effectively becoming variable transparency smartglass

Fully Integrated Hybrid Silicon Two Dimensional Beam Scanner | Bowers
The underlying tech behind Strobe Inc.'s (now GM/Cruise) fancy pants chip LIDAR. Uses optical phased array for one dimensional scanning, and frequency variation through a prism lens to achieve scanning in the other dimension, rather than a full 2D optical phased array (so easier to make?)

MarineBiomass – The official home of Marine Bio Energy
Uh using variable depth buoy/submarine setups seems a bit overkill, could achieve most of the same result with a long pipe for a local deep ocean upwelling to bring the necessary nutrients to the surface. But open ocean kelp farming is an interesting concept itself.

Locally and Dynamically Controllable Surface Topography Through the Use of Particle-Enhanced Soft Composites - Guttag - 2015 - Advanced Functional Materials - Wiley Online Library
So unstretched/uncompressed elastomer has smooth and flat surface, but by compressing or stretching it, embedded hard particles cause surface deformation. Useful for things like tactile interfaces, surface drag reduction, anything that involves surface features. The tactile interface usage will probably be used for adult toys though...

Bioinspired fibers change color when stretched — Harvard School of Engineering and Applied Sciences
Interesting photonic fiber research, which resembles dichroic materials, but because it is stretchable, allows active changing of the color by adjusting the bandgap. Possible uses in smart cloth showing deformation damage, or as a possible active camouflage textile system.

The Superjet: Engineers at GE Aviation Are Building the Ultimate Jet Engine | GE Reports
Thing is, the tech path for this leads to a similar family of engines, like the J58 that powers the SR-71 (two path engine with outer duct not behind a compressor and used as a ramjet), and SERJ (technically a two path where you have part of the compressor flow go to a combustor and turbine segment, while the rest flows to a ramjet combustor only). Probably the basic difference between ADVENT and SERJ is a lack of subsonic ramjet combustor and an air bleed path.
