   I've helped build some pretty exotic lab prototype vehicles that need a   
   full-time mechanic to keep them running, the same as race cars and fighter   
   planes.   
      
   They were "real" and functioned as intended but were nowhere near practical   
   or ready to sell to the public, which is the true goal that developmental   
   prototypes should lead to. Otherwise they are just engineers playing at   
   their hobby and trying to sucker you into paying for it, the way the   
   entertainment industry does.   
      
   Even GM can build a failure, as with the Wankel engine. The problems that   
   kill them are never mentioned in the press releases. Research the   
   thermodynamic efficiency of a steam locomotive, for a good example.
