The Peerless turbine is a work of art whose primary inventor is a lifelong kinetic artist who has
created massive public art commissions that interact with the wind for over 40 years. In Peerless
Wind Systems, Robert Perless works hand-in-hand with engineers who are deeply experienced in turbine
evaluation. One reason why the Peerless Wind Systems helix turbine is more than just a pretty face.
Unlike ordinary helix turbines, because of its 270° arc, the rotating motion of the PWS
turbine is almost mesmerizing to watch. As it creates power it also creates a beautiful environment.
Its nearly silent operation ensures low impact to the site area. Regenerative braking controls
to continue operation in high wind conditions. PWS turbines were tested in real time during Hurricane
Sandy in CT at sustained winds of over 70 mph. Survival speed is 110 mph.
But the beauty of the Peerless helix turbine is more than skin deep. It is also almost completely
silent and self-starting with a cut-in speed as low as 2 mph (our largest competitor has cut-in speeds
of 8 mph.) Even in environments such as NYC, where summer winds can drop down as low as 2 or 3 mph, the
PWS turbine will continues to operate, although there is not very much energy to convert to electricity
at the lowest wind speeds.
While the PWS turbine efficiently processes airflow, it produces substantially no vibrational
effects. The vibrational effects generated during operation of many turbines may be translated throughout
the structure of the building, resulting in shaking or even structural cracking. Vibrational effects also
produce a great amount of wear upon the turbine itself. Another problem with small-scale turbines is that
they process turbulent airflow inefficiently. That is a particular problem in urban environments in which
surrounding buildings disrupt airflow, thus increasing turbulence.
While other helical turbines on the market have few design innovations that distinguish them from
the original patent filed by Alexander Gorlov in behalf of Northeastern University in the 1990's, the
Peerless Wind System turbines represent a true design innovation.
