From what I've read a straight diesel. Can't see a diesel-fuelled turbine justifying a tech demo program (fill it up and fly away).

Not true. Dave Jackson probably has better insight, but there are several more powerful designs in development, incl. 450shp & 600shp units. You'd have thought that 21st century diesel tech would be able to at least challenge the 1960s technology in the RR300 (C20), but who knows. DARPA was planning to go diesel on the A160 Hummingbird at one time, but this effort seems to have stalled, with a switch to a P&W donk.
Since Westland is also involved in that Clean Sky effort, I look forward to seeing a diesel-powered EH101 with BERP IVs before too long.
