Tesla Turbine design by Phoenix Navigation (http://phoenixnavigation.com/shows/engine/ttsld01.htm).

Directory of Tesla Turbine technologies.

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. The technology has been proven to work but is yet to break into marketplace in a cost-effective version.

• PowerPedia: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.

• Tesla Turbine: Engine of the 21st Century? (http://pesn.com/Radio/Free_Energy_Now/shows/2007/04/14/9700225_KenReili_TeslaTurbine/) - The Tesla Turbine could far surpass the efficiency of the internal combustion engine. Recuperative hydraulics can be used for low-speed, high-torque needs. (PESN; Apr. 14, 2007)
  

• Tesla's Turbine (http://www.saipantribune.com/newsstory.aspx?cat=9&newsID=47147) - Today, Tesla turbines can be used in a number of practical settings. Co-generation of electric power uses waste heat from conventional diesel generators to provide additional energy from the same fuel, which makes the entire process more efficient. They can also be used for generating electric power from hydro, thermal solar, and ocean-waves. (Saipan Tribune; May 13, 2005)

Builders

• Global Energy Technologies, Inc. (http://www.frank.germano.com/theturbine.htm) - Frank Germano replicated the Tesla Turbine and has had a turbine in continuous operation without component failure since October of 2000. An engineering report posted on his site says that the "Charlie" replication of his company is documented as achieving a 42.2% efficiency at 13,000 rpm, with 14.8 horse power output. Note: See Contacts below.

• Centripetal Dynamics (http://www.centripetal-dynamics.com/projects_ert.htm) - The TurboFlux™ PGS consists of a series of flat disks mounted on a shaft and rotating within a casing. The steam [or gaseous products of combustion] enters with high velocity at the periphery of the disks, flowing between them before escaping through exhaust ports. Fluiditic properties of adhesion and viscosity literally pull the turbine rotor around.

• Sustainable Energy Developments (http://www.sustainableenergydev.com/) - Developing grid independent power systems with Expanding Gas Turbines (http://www.australiangoldholdings.com/web07/assets_resource.html) – a Bladeless, Bearingless, Ejector Style turbine with 50% to 80% greater efficiencies than traditional turbines. The ability to use low grade ‘wet’ steam and renewable power such as solar thermal, will enable it to produce power at a price comparative to the grid. Demo Model August, 2007. Commercialisation March 2008.

• Build a 15,000 rpm Tesla Turbine using hard drive platters (http://www.instructables.com/id/E5R0LEN6OFEP287CZL/) - To build a turbine like this (http://staff.washington.edu/sbtroy/turbine/turbine.html), you need some dead hard drives, some stock material (aluminum, acrylic), a milling machine with a rotary table, and a lathe with a 4 jaw chuck. I run my turbine on compressed air (40 psi), and it easily reaches speeds of 10-15,000 rpm. While the speed is high, the torque is low, and it can be stopped with your bare hand.
  

• Gyroscopes Online (http://www.gyroscope.com/d.asp?product=TESLATURBINE) - This affordable production tesla turbine has been designed for educational use and also to promote Tesla turbine technology. It runs from air pressure and generates electricity from a 3 phase AC motor/generator. It has a see through design that enables visual inspection and easy explanation of the technology and forces.

No. 1,061,142 and 1,061,206. For this reason, these turbines are sometimes referred to as Tesla Turbines, but are alternatively known as Prandtl layer turbines, boundary layer turbines, cohesion-type turbines, and bladeless turbines.

Theory

• Uneven surfaces conserve fuel (http://www.physorg.com/news11095.html) - Tiny regular bumps on a surface, such as the wing of an airplane, can substantially reduce total air resistance, and thereby the consumption of fuel according to wind tunnel tests at the Royal Institute of Technology in Stockholm, Sweden. Note: This is a corollary principle to why a Tesla turbine works. (PhysOrg; Feb. 22, 2006)
