asteroza + ignition   8

Weird design. Uses 5 caseless rounds with their receivers stacked as a brick, such that you eject the brick and heat. Electrically fired, very simple, but you need five barrels but they claim only one (5 bore, "single" barrel)? sorta Metaltorm in concept without tossing the barrels

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.

pulse plasma engine working at 1 atmosphere, sorta PDE, looks interesting but needs high power (remote beaming?), so looking like something for airships for now.
