1 connection, 7 balloons, 1,000 kilometers – Loon Blog – Medium
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.

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.

biometrics
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...

Govt aims to triple wind power : Business : DAILY YOMIURI ONLINE (The Daily Yomiuri)
Oh that's sleazy, forcing the wind power generators to basically underwrite half the cost of the transmission system upgrades to send power south from the cold windy northern prefectures that the local utilities and conventional power producers were totally unwilling to put up with the cost of putting in such transmission networks themselves. The interesting takeaway is the planned grid energy storage at major substations to even out wind power production. Sine the wind companies are forced to make their own independent transmission networks, I wonder if they will charge penalty fees on the local utilities to use the network, since they forced the capex onto the wind companies.

Electric Airplane Design Uses Flying Drone Batteries to Boost Range | Autopia | Wired.com
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).

Sandia did a new study for persistent UAV's using unusual configurations for power and propulsion, effectively turning them into low altitude satellites. Which shortens to "Hey, what if we stick an RTG into a medium sized UAV that is really lightweight?" and other neat ideas. RTG sensor blimps might be interesting. Would like to see full report details though...

Company specializing in remote control underground mining vehicles and equipment. Apparently a Dr.Greg Baiden has prototypes for a wireless optical high bandwidth communications system for underground remote mining operations (necessary for the high bandwidth/resolution video feeds to remote control mining vehicles and equipment). Long term aim is to use this with ROV/AUV underwater subs to cut the tether.

Public entity eyed for power supply : Business : DAILY YOMIURI ONLINE (The Daily Yomiuri)
So the government is using the opportunity to pimp slap TEPCO into allowing a power grid ISO. Still kinda daft to have two ISO's for the 50/60Hz split, but understandable since the transfer limit across the divide is so low. Which might change if Son gets his way with his offshore HVDC grid intertie, which having an ISO exist would facilitate.

Official Google Blog: The wind cries transmission
The other shoe drops regarding Google being a power broker. This offshore long distance transmission line network kills two birds with one stone; power leveling wind turbine output by averaging over a large geographic area, and new long distance transmission capacity with little to no NIMBY blockage (because it's very difficult to block what people can't see and is beyond the 12 mile limit) carrying power from southern US power producers (which includes the new nuclear reactors in Georgia). No other major power broker can probably bring online such large north-south transmission capacity using existing rights-of-way, and will likely have to either buy into the project at a disadvantage, or end up getting screwed by Google later in the power spot markets.
