This is another one. NASA should forego the Holy Grail of diesel level fuel
consumption
and just get a bunch of them in the air.

Abstract: 
      The original goal in this program was to combine some of the better features of
reciprocating and gas-turbine engines; thus, obtaining a superior powerplant
      for light aircraft and a host of related uses. Based on a series of engine and
aircraft/mission studies conducted in the early 1980's, the rotary (Wankel)
      engine was perceived to have many of the desired features and was judged to be
capable of considerable further development. At the time, existing automotive
      rotary engines had demonstratably high power outputs in a compact,
smooth-running, and reliable package but were less fuel efficient than comparable
      reciprocating engines. Accordingly, the basic thrust of the NASA Rotary Engine
Technology Enablement Program was (and is) to bring the rotary's efficiency up
      to the level of a comparably sized diesel, without sacrificing its other
desirable features.
