      The Tesla turbine is a device of many possibilities. It will run on
      steam, air pressure, hydro power, or direct combustion. The turbine can
      be used as an engine, a pump, a vacuum, or a compressor. The turbine has
      only one moving part and will tolerate particulate that would destroy a
      normal turbine. A Tesla turbine with 10 inch diameter rotors 4 inches in
      width, can generate 110 hp. An 18 inch turbine, four inches wide can
      generate 250 hp and under some conditions 650 hp. The average car engine
      is right around 200 hp.
      Seemingly complex the turbine is a simple machine. It consists of flat
      circular plates attached to a shaft. Spacers between the plates provide
      an opening for steam or other working fluid to move between the plates.
      The flat plates (rotors) have a central exhaust opening as does the
      containment housing. The rotor section and shaft turn inside a circular
      containment housing. Working fluid (in some cases steam) enters the
      containment housing at a tangent to the rotor section and exits at the
      center opening along the shaft. The turbine utilizes a unique method of
      propulsion. Working fluid entering the rotor section ADHERES to the
      rotors and DRAGS them.
      Adhesion is caused by the tendency of a fluid to stick to a smooth
      surface. Drag is produced when steam enters the narrow gap between the
      rotors and cannot pass through easily due to the steam adhered to the
      rotors. The steam adhered to the sides produces a boundary layer similar
      to the ones noted on airplanes. That is why the turbine is frequently
      referred to as a boundary layer device.
      Tests of the turbine are inconclusive. The preceding is an incorrect
      statement. Much of the test results for the turbine are due to incorrect
      construction. Over the years several people have built their own version
      of the turbine only to have it fail for one reason or another. From my
      research this occurs because they fail to follow the general principals
      of turbine construction. My next post will outline some of the general
      principals that allow the turbine to function properly, as well as some
      of the mistakes that can be made in construction.
