Interesting engine that works on expansion of liquid nitrogen as the working fluid in a piston engine (similar to compressed air engines), but the real savings is for refrigerated goods delivery vehicles, that can use the cold exhaust for cooling cargo. Wonder how well it pairs with hybrid electric drivetrains, or functioning as a range extender?

Airbus Group and Siemens Sign Long-Term Cooperation Agreement in the Field of Hybrid Electric Propulsion Systems - Siemens Global Website
Siemens has been doing aircraft propulsion electric motors recently, guess they felt it was better to cooperate with the Airbus E-Fan group rather than compete. Wonder how the turboelectric work will shake out though?

Interesting comment on a novel dual injector hybrid rocket. I wonder for a practical rocket, the lower injector could use something similar to a reverse vortex combustion chamber, where the HTP is swirled up from the throat, providing some cooling to the throat area?

Interesting brushless DC motor design for underwater propulsors. On the face of it, I guess what they did was coat a conventional BLDC motor internals with some sort of waterproof coating, and fiddled with the shaft bearing seals. How well will it stand up to saltwater though?

Apparently did some research work for NASA recently that found a N+2 design for a non-superconducting turboelectric propulsion that actually closed and was usable, roughly on par with an existing 737. Uses strut braced midspan turbogenerators feeding power to the inboard wing span, which is stuffed with wing internal embedded electric propulsors. Though the design used tech that while it exists today, exists outside of the aerospace realm so requires further development. They also have a superconducting N+3 design too.

EcoSpeed, Worlds Best Electric Assist
Electric drive chain motors for bikes/trikes, very high power. Not a hub motor, so the motor design isn't pancake style, which has it's merits/demerits. Commonly used as a "mid-drive", which allows the motor to utilize existing bicycle gearing, but also means it can't regeneratively brake like a BionX.

If you avoid rotating the cylinder/piston path and only rotate the nutator (using a sine wave swashplate and cam rollers on the rods), you could potentially do an opposed piston layout and have the opposite piston drive a lock synced counter-rotating shaft to reduce vibration.
