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...

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.

OSA | Computational imaging enables a “see-through” lens-less camera
So if about 1% of light passing through a glass pane can go to the edge, you can sorta recover the image going through the glass. This could effectively turn a display into a camera using an edge camera, rather than directly embedding sensor pixels into the display pixel array.

Supercritical Organic Rankine Cycle waste heate recovery generator for marine ga...
Interesting, for marine propulsion applications that use a gas turbine (selected for compactness/high power), exhaust gas waste energy recovery would be better served by a higher efficiency HRSG steam turbine, but the balance of plant of a steam turbine is so large that a supercritical organic rankine cycle, despite the lower efficiency, wins due to compactness pairing with the compact gas turbine.

Former GamerGate victims are now doing protection/support services for online cyberbullying, from low end stuff up to Anonymous.

GT | News Center :: Harvesting Electricity: Triboelectric Generators Capture Wasted Power
A rubbing type kinetic energy scavenger power generator system it seems, using an electron donor sheet, a electron hole sheet, and some sort of bridging electrode. So apparently they have demoed a 10cm disc shaped 3K RPM version generating 1.5W at 24% efficiency, which seems to be 3x piezoelectric (but how would you do a 3K RPM piezoelectric generator to begin with for comparison anyways? I guess they mean 3K impacts per minute)

Welcome to Rentricity
Smart idea to recover energy lost in water pressure regulator vaults, which convert high pressure water mains to lower pressure water for neighborhood water pipes. Rather than a typical pressure regulator, this uses an inline water turbine to extract energy while reducing pressure. A very "hidden" distributed generation opportunity.
