Here we have a 10m Commercial Vertical Wind turbine, with 4mm Steel Column, All the generator, wiring is incorporated within the column and the slient running vertical Turbine not only makes it look pleasing to the eye, but safer without long blades spinning.

The Vertical Turbine is a Commercial trade Model, shown here supping an optional street light and power for the ticket machines in a local town centre carpark.

Studies and initial assements show that by installing an eviromently friendly turbine such as this is often cheaper than installing and getting a power supply to the site, as well as maximising your green targets with the most efficent use of engery for a local authority owned project or scheme.
