   Since the subject of turbopump alternatives comes up fairly regularly   
   the following recent (and interesting) paper might be of interest:   
      
   Knight, Andrew, "Designing and Testing a Lighter, Simpler, Less-   
   Expensive Liquid Propellant Pump", Journal of Propulsion and Power,   
   Vol. 20, No. 1, Jan-Feb, 2004.   
      
   The pump he describes seems remarkably similar, in appearance at   
   least, to the Comprex supercharger.   
      
   The author, Andrew Knight, identifies himself as the proprietor of   
   Andrew Knight Space Propulsion. A Google search didn't turn up any   
   additional information.   
      
   If you can't find a copy of the paper you can look up his patent #   
   6,499,288 online.   
      
   Does anyone have any additional information or opinions about Mr.   
   Knight and his pump?
