Aster Thermoacoustics
Interesting work on both thermoacoustic heat sources and matched bidirectional turbines for electrical power generation. Thermoacoustic electrical generators previously used linear alternators, but those prefer faster cycles, which is opposite what the thermoacoustic wants (parts sizing goes up unfavorably when scaling), and slower long stroke linear alternators also have issues (long piston stroke, sealing issues). Using a rectifying bidirectional turbine may be a convenient workaround.

Interesting, for marine propulsion applications that use a gas turbine (selected for compactness/high power), exhaust gas waste energy recovery would be better served by a higher efficiency HRSG steam turbine, but the balance of plant of a steam turbine is so large that a supercritical organic rankine cycle, despite the lower efficiency, wins due to compactness pairing with the compact gas turbine.

So, using lasers to fuse deuterium over a pusher plate/bell nozzle,which is lined with uranium to heat up from neutron capture, which heats coolant, which runs to a turbogenerator, which powers the laser. So sorta pulse like, sorta orion-lite? It's not your typical fusion-fission hybrid setup. The implication is that this could be used as a nuclear jet engine the atmosphere (ejector ramjet entrainment maybe)?!?
