sitevisor.us | SiteVisor: Real-time Cyber-attack Alert System
So they're selling Sitevisor abroad now. Still primarily an unused network segment access monitor though (they use the word darknet, but I think that's the japanese interpretation/definition and not referring to tor like hidden networks)

Towards a ‘proton flow battery’: Investigation of a reversible PEM fuel cell with integrated metal-hydride hydrogen storage
Now that's smart, integrating a metal hydride hydrogen sponge as an electrode in a PEM fuel cell to skip a step. Though it turns the setup essentially into a closed cycle battery, fixed to the capacity of the metal hydride electrode's internal storage capacity, hence the "battery" nomenclature.

Interesting biomimicry, using piezoelectric sensors emulating lateral lines to detect disturbed and smooth flow, allowing a robot trout to seek smooth current flows (or even calm eddy spaces behind objects), to reduce drag and propulsion power.

I wouldn't have expect a side suction slot that ends up reversing the flow completely before it reaches the fan (360 degree flow path change) would have improved things.

PVDF microbelts for harvesting energy from respiration - Energy & Environmental Science (RSC Publishing)
Interesting. I suppose one concept is direct implantation to power body internal devices, but then you would have a weird wheezing buzz in your chest when you breath. The other obvious one is mounting in a mouthpiece/respirator to power small sensors/devices in breathing gear, such as SCUBA or firefighter respirators or even regular gas masks

Ecomerit Technologies
Key point is some kind of distributed drivetrain setup, where you have large torque delivered via a huge wheel, and multiple takeoff/off-take drives drawing torque power off the big wheel. Each individual takeoff drive runs a generator of smaller size, so you don't have to deal with the expense of trying to build a larger monolithic unit, in theory.

Primus Power: Smart Grid Storage
Basically, avoid custom tanks for flow battery sites and base it on modular rack boxes (about a residential hot water heater in size), and focus on mass production economies of scale to improve the costs. Otherwise, you tend to keep running into first of a kind types of costs. You loose some efficiencies, but the argument can be made that you can increase total flow by dispersing valves and pumps. Making the whole thing modular has benefits for site expansion and minimum hardware for initial operations.

Small-scale waterwheel hydropower generating buzz across Japan - The Mainichi Daily News
Considering most "rivers" and "brooks" are concrete ditches in japan, it's not that big of a deal to put in a small waterwheel for auxiliary power. I think the trick would be to design in energy storage at the waterwheel to be released during the daytime, if the water wheels are located in more rural areas. Possibly a simpler route to test early distributed grid generation capacity?
