Faradaically selective membrane for liquid metal displacement batteries | Nature Energy
Sadoway has a new variant of the liquid metal battery, a liquid displacement metal mesh battery. Some sort of porous membrane in the center?

AMW - One Stroke for mankind
This is a pretty strange engine design. The problem point will probably be sealing between the blade "piston", the crankshaft disc slots holding the blade, and the duct walls. Which might be mitigated by keeping the ducts at most a half cylinder in depth where the blade dips out most from the crankshaft disc.

Guided Rotor Compressor
Very similar to a wankel rotor, but apparently not the same, and uses rollers at the apex seals. Hrm, I wonder why wankel rotors don't use cylindrical roller seals for the apex seals?

They're claiming possible 120:1 pressure ratio single stage compression due to key heat transfer method with a water cooling jacket?!? Something about the hybrid rotor combining aspects of centrifugal and reciprocating compressors. Some kind of sliding block to emulate a piston on the rotor itself?

Hydraulic series hybrid with regenerative braking via the pressure accumulator, as an alternative to electric series hybrid vehicle systems. Applications for wind turbines as a replacement transmission (though what about remote transmissions to put the generator on the ground to reduce weight aloft?)
