Now this is interesting, using 2 cam rotors to move two pistons per cylinder in a rotary OPOC config. Sorta uniflow as well?

QUADRUM - SteamMotor Mini Power Plant: Combined electricity and heat production (CHP = Combined Heat and Power)
similar to liquid piston, being a reverse wankel, but rather than LP's lozenge piston, this one uses a square, which ends up forcing the seals to be on the piston like a wankel, which negates the reverse wankel's primary advantage of tip seals on the cylinder wall (allowing cooling/lube)

Cyclone Power
External burner/heater for stirling piston hot side, so can basically burn anything that won't clog the hot side heat exchanger. Was going to be demoed on EATER, some kind of land foraging robot that uses available biofuels (grass/sticks it can pick up) to self-power

interesting rotary expander piston engine, but those vanes have to take on a lot of force. A gerotor seem like an easier way.

Nuclear piston engine, using gaseous "fuel" and hydrogen gas moderator, with neutron reflector piston and cylinder. Uses piston top-dead-center compression effects and a "spark" (external neutron source, like an ADSR particle accelerator neutron spallation target, or some sort of cylinder wall embedded neutron source). Wonder if LiquidPiston reverse wankel would also work well here. Negative void coefficient is nice too.

There's a pic in a Popular Mechanics June 1998 article showing the nuclear piston engine using a steam working fluid/moderator with nuclear fuel in the cylinder/piston. Same guy went on to CAESAR reactor work which is similar, using fine tuned light water steam pressure for neutron economy control.

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?

Appears to be a linear free piston ICE engine, probably for range extender work. Uses a piston rod linkage to connect the free piston to external rods that mount the generator stator coils, so the generator portion isn't in the hot cylinder/piston (though that means a a sliding seal for the piston rod to exit the head)
