infinite-cooling
This is borderline cooling version of a perpetual energy generator, but this is an interesting take on fog net concepts. By lightly ionizing the fog and the capture mesh/net, you can get fog droplets to condense better on the net and exceed normal fog nets (which capture 1-3% of passing droplets).

Soft material for soft actuators | Nature Communications
An ethanol infused 3D printed silicone matrix apparently makes for a pretty good soft actuator that requires low activation energy, but it is effectively thermal based, which makes environmental conditions and position holding a pain

Anomalous water expulsion from carbon-based rods at high humidity : Nature Nanot...
Nanorods, take on water at low humidity, eject at about 50% humidity, then reuptake as humidity rises higher. Weird sponge effect.

Air HES
Slightly insane airborne hydroelectric powerplant. The idea is to use a tethered blimp holding a fog/dew/cloud catching screen to grab water from air/clouds, with the tether doubling as a tube. The hydraulic head is non-trival, and can be shunted through through a water turbine to make power and recover the water for purification. If the generated power is enough, I suppose you could generate hydrogen gas on site for the blimps.

Welcome to Weber Manufacturing (MFG)
Interesting nickel vapor deposition manufacturing tech, for making liners and such. There was a suggestion of using depleted nickel as a liner for molten salt reactors in the core, so their manufacturing tech might fit well with the concept.

Solar Vapor Generation Enabled by Nanoparticles - ACS Nano (ACS Publications)
Really weird solar steam generation using wideband visible light absorbing nanoparticles suspended in water. Apparently, you get local vapor production on the surface of the nanoparticle. Because of the small surface area relative to the energy involved, and the size of the particle being below the wavelength, it causes unusual steam generation. It seems it's possible to create steam without heating the entirety of the liquid volume.

Interesting work on using a MHD on the output of a vapor gas core nuclear reactor to make power for space applications. Potentially reduces the cooling necessary for the overall cycle as it isn't a direct heat engine.

Diode Pumped Alkali Lasers Could Eventually Enable Practical Airplane Based Laser Anti-Missile Systems
I can faintly hear the "Duh, why didn't I think of that!" resonating amongst a mass of laser scientists. Using a hybrid approach can achieve some goals, but I wonder in terms of overall cost of ownership and applied MJ/$ if this is really better than solid state only lasers. Especially with some of the fiber laser stuff that's been happening.
