Tesla Turbine -- Bladeless Boundary Disc

Rather than using blades and friction, the Tesla Turbine uses parallel, closely spaced disks that tap viscosity.  Aerodynamic skin adhesion effect resists fluid or gas flow between plates, resulting in energy transfer to the shaft.  Technology works but is yet to break into marketplace.

Discussion Lists

  • Members > TeslaTurbines
    (CAUTION: could be a porn list.  Another list by a similar name was taken over by pornsters.)
    "Dedicated to the work and inventions of Nikola Tesla, the turbine site discusses specifically the turbine and uses of this prime mover. Other topics of discussion related to science and physics may also be posted. The overall goal of this site is to explore ALL areas of science and physics. Inventions of Nikola Tesla include alternating current, robotics, turbines, dynamos, pyromagnetics, Tesla coils, oscillating generators, and electric motors.
  • Germano > TheTeslaTurbineList
    To promote the technology of Nikola Tesla, with particular emphasis on the Tesla Bladeless Boundary Disk Turbine and Pump. This list will also be used for forwarding any and all technical developements on the turbine and pump and the date of their hopeful commercial release to the list members.


  • The Tesla Bladeless Turbine and Related Turbo Machinery by Gary L. Peterson.
  • Tesla's Engine: An New Dimension for Power - by Jeffery A. Hayes (Editor) - UA scrapbook reprinting of what appears to be everything the editor could find written about Tesla Turbines. Great collection of reprints of Tesla turbine patent applications and circa 1911 newspaper and magazine articles.  Lacking in clear presentation of higher-level engineering technical information.

Chrisitan Allan holding a Howard Johnson Magnetic Motor prototype; Jan. 2004


ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, (3) the group has the ability to make a success of the endeavor.
All truth passes through three stages:
   First, it is ridiculed;
   Second, it is violently opposed; and
   Third, it is accepted as self-evident.

-- Arthur Schopenhauer (1788-1860)
