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...

Scalewings – Willkommen in der Welt von ScaleWings
Trying to build a hybrid engine block for airplanes, consisting of an electric motor/generator and two independent reciprocating engines (looks like V type). In theory, with a shared shaft, you can knock out one motor and two others should still cover you.

DLR Portal - News - DLR researchers unveil a new kind of range extender for electric cars
Using a gas piston to keep the linear generator rod from smashing through the cylinder end works, but it seems more like they are using the linear generator as a braking motion limiter (reverse generator to motor mode) to keep from overwhelming the gas piston.

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.

SkySails GmbH - SkySails Power System
Interesting. A pull/retrieve power stroke based, figure 8 racetrack pattern autonomous flight pull stroke, offshore floating buoy based parafoil wing kite power generator system. System will need a rather large energy accumulator/battery/flywheel/capacitor to even out the energy output from an array of these though. Could do that at the array level, or at the individual buoys. Buoy based does not favor all electric flywheels (maybe CVT clutch coupled mechanical flywheels), clutched air compressor based systems would also work, capacitors probably would be undesirable though. That water pump spherical anchor may be favorable if using a TLP platform style pipe tendon for moorings

DLR Blogs - Energie-Frage der Woche: Mit welcher Technik lässt sich Energie überhaupt speichern?
So this dude Mathias Popp is applying for (or has) a patent for an above-ground pumped hydro reservoir design using an earthen ringwall island in the middle of a converted open pit mine lake. Apparently there is a trend to convert disused open pit mines to lakes anyways, and considering the mine itself is considered already fowled and "brownfield", it shouldn't be that hard to make the center island ring.

Willkommen bei Solar Fuel
This is the company doing collaborative research with the Faunhofer institute to make small scale combined water electrolysis/syngas to methane production systems for renewable energy storage and synthetic fuel production. Arguably carbon neutral fuel to boot, since the syngas is made via hydrogen liberated from solar powered electrolysis, and CO2 provided from other sources (such as a carbon capture system at a combustion powerplant).

Achtung, YouTube: Germany Proposes Federal ID Checks for Online Video Sites
Seems government officials may be angling to follow the South Korean model in an attempt to perform public safety and law enforcement functions on the internet regarding viral video, but going a step further to go after the mobbing viewers as well, rather than just going after the uploader, who is arguably the only responsible person to nail to a wall. Logging the viewers kills freedom of speech and freedom of association by design. Though some people have said this wouldn't work with existing data privacy laws in germany and the EU, so who knows, though even odds they'd just slip something in like the new EU logging regulations to make it all legal...
