Apparently one could do similar with existing HSMM-mesh setups for several years now, minus the antenna pointing. Plus there is the grand-daddy of it all, the AT&T long lines network (though that was point to point and really mesh). Notable that this appears to be microwave, judging by the antenna, and not lasercomm.

Appears to be a linear free piston ICE engine, probably for range extender work.

Cancellable biometrics is kinda important from two perspectives. It requires some additional authorization beyond the image itself, and can be effectively revoked by "losing" the original encryption key/PIN. Balancing against this is very long range iris capture and recognition using COTS cameras against potentially uncooperative subjects, which would really help a police state monitoring large areas and transit chokepoints...

ebuggy - a global solution for electric mobility
Battery only EV range extender via a battery trailer. I seems the idea is to rent a trailer from a gas station before entering the autobahn/highway system, and drop it off when you exit. The gas station has the necessary charging infrastructure as well as a small fleet of trailers to cover demand. Assuming the range is insufficient, swapping/mounting trailers seems to take about 2 minutes (plus the driver could add 5 minutes because people suck at backing up trailers). Seems to be a battery carrier trailer, so is not a motor pusher trailer, and contains no generator, so the stranding problem still stands.

Electric Airplane Design Uses Flying Drone Batteries to Boost Range | Autopia |
Interesting concept for "drop tank" batteries for electric aircraft, which can operate like UAV's on their own, with the potential for linkup/docking with fresh batteries in route. I wonder if the reverse could be done, jet engine boosters that can fly back to the launch field for electric craft, to boost climb performance early on? Sorta JATO booster-ish, either as direct thrust (easier) or as auxiliary power for the existing electric drive (harder).

Tacocopter: One-click Taco Delivery in the SF Bay Area
This feels like something out of some cyberpunk novel. Fake website since it is still basically illegal to use UAV's for commercial work due to the FAA, for now, nevermind the difficulty involved. Domino's japan has an iPhone ordering app that grabs GPS coordinates so a pizza can be delivered to your exact location, so this is the next logical step in mobile apps/food delivery as well. If this kind of usage takes off, we are going to need to seriously discuss the issues surrounding collision avoidance and local airspace control, probably beyond something simple like transponders, more like AIS (vehicle ID,location, state vector, perhaps expected flightpath or destination). Also, you just know Dr. Claw must be involved with the Lobstercopter...

Interesting idea here. A medium sized trailer for pure EV's, featuring conventional cargo area, a battery bed to store energy, a small diesel generator, electric motor to power the trailer axle (so the EV doesn't feel the weight of the trailer), and power transfer to keep the host EV' batteries topped up (or direct feeding the EV's motors if the host's controller is intelligent enough) with the potential to do a normal charge of the EV when parked. Since you probably need the cargo capacity if you are going on a long trip, this actually makes some sense. Plus this covers the EV owner's fear of being stranded from charging infrastructure, without having to carry a generator engine onboard all the time like a normal hybrid EV.

Enerfuel Main |
Moderately high temperature proton exchange membrane fuel cell than can use less than clean gas from an onboard liquid fuel reformer for vehicle applications (small size specifically for cars). Basically a range extender in the 3-5KW class. The idea is to run the fuel cell almost continuously all day, based on the assumption that while the fuel cell won't meet average driving power needs, it does fulfill daily total power consumption needs, averaged over 24 hours. So you use less battery than you normally would, but you still run the risk of absolute power loss. Basically, this is range extension for commuters, not true long range extension that could be refueled for immediate go power. Which isn't a bad compromise, and generally puts you into the same camp as pure EV's, but without the onerous 8 hour recharge requirement to get a full day's worth of range.

Sounds like the gas turbine they describe is a Capstone MicroTurbine due to the no lube and no cooling setup, but they don't explicitly say that, since their main engineering is on a series hybrid controller and battery management architecture, which theoretically can accept any input generator power source, and to a lesser extent can be used for retrofits of existing vehicles by slapping in a generator where the transmission is now.

Revolutionary Communications System Promises New Generation of Untethered, Undersea Vehicles
200m range isn't much, but if you set up a mesh network of these near an underwater platform you could potentially do autonomous survey/monitoring runs. The other thought being dropping a long tether-like cable with these optical modems at 100m intervals with a small ROV at the bottom to drag around the end of the cable, operating like a mobile accesspoint for other ROV's and UUV's/AUV's. The military application would be a sonar buoy accesspoint connecting to a sonar module that drops below local thermoclines to see under them.
