It's being built to test the EmDrive, but it might be useful for testing the   
   Mach Thruster too:   
      
      
   "The resolution lies in designing a tool that can measure these minuscule    
   amounts of thrust. So a team of physicists at Germany’s Technische   
   Universität    
   Dresden set out to create a device that would fill this need. Led by physicist    
   Martin Tajmar, the SpaceDrive project aims to create an instrument so   
   sensitive    
   and immune to interference that it would put an end to the debate once and for    
   all. In October, Tajmar and his team presented their second set of   
   experimental    
   EmDrive measurements at the International Astronautical Congress, and their    
   results will be published in Acta Astronautica this August. Based on the   
   results    
   of these experiments, Tajmar says a resolution to the EmDrive saga may only be   
   a    
   few months away."
