Tesla Turbine Concept
After extensive researches on the current wind technologies
our conclusion was that these technologies face overwhelming problems
for their installation in urban areas.
Extending our researches to find efficient turbines,
a long forgotten remarkable technology caught our attention: the
bladeless steam turbine produced in 1913 by Nikola Tesla. Rather
than using blades and friction, the Tesla Turbine uses parallel,
closely spaced disks that are set in rotation by the adherence of
the fluid on the disks surface, steam or oil in Tesla experiments.
In the Tesla design, the disks were enclosed in a volute casing
and the fluid was projected with very high pressure on the tangent
of the disks. The Tesla turbine is recognized for its high efficiency
and its robustness.
