Product Description
The Quietrevolution Qr6 is a vertical axis wind turbine designed specifically for urban environments. The design eliminates downtime from changing wind direction due to vertical axis design, possesses an aerodynamic helical blade design to minimize vibration, and has quiet operation to allow for installation in public places. The Qr6 vertical axis wind turbine is designed and manufactured in the United Kingdom.

Description of control system
A turbine controller, inverter, OFGEM approved electricity meter, and protection relay for grid connection are all provided as part of the Control Electronics Panel. Auto-shutdown sensors are also incorporated into the design to detect any uncharacteristic movement or impact to the turbine.
Design Specifications
Components and Operation • Blades: Carbon fiber • Generator: Direct drive, mechanically integrated, weather sealed permanent magnet generator • Power control: Peak power tracking, optimizes turbine output for all sites and windspeeds • Roof mounting: 6m mast • Tower mounting: 15m or 18m ground mounted • Remote monitoring: Event log can be accessed via PC. Remote monitoring stores operation, average wind speeds and kW hours of electricity generated • Dimensions:
- 5.5m height, 3.1m diameter, and 16m2 swept area.
- With the mast, the height is either 6m or 18m.
Technical Support
Provided by Quietrevolution.

Lifecycle
Has a design life of 30 years +.
Manufacturer Specified Performance Parameters
QuietRevolution outlines is goals here, included producing energy on the site of consumption and reducing the carbon footprint of urban centers.
Vetted Performance Status
Unknown
Safety
Auto- shutdown sensors incorporated into the design to detect any uncharacteristic movement of or impact to the turbine.
Complementary Technical Systems
The generator is a through bore permanent magnet motor/generator unit directly coupled to the rotor. It is used both as a generator and as a motor to the spin the rotor up in response to initial or sharp increases in wind speed. A three-phase grid connection is required. Please contact Quiet Revolution if there are requirements for single phase or off grid/battery version.

Leaving a brief overview of the clean-up.
-Seemed like details about the QR5 (the previous model) were widely available with multiple sections and subsection on their website, unlike QR6 which is very covertly presented.
– I have removed most of the links from the QR5 product report as all those URLs lead to a broken/expired page. However, I have retained certain aforementioned contents which should be applicable for both QR5 and QR6 (even though links for qr6 arent available). For example: Target Users, user provisional model, product IP, etc.
– While Wikipedia suggests this product has been DISCONTINUED! We might need to contact the manufacturer to verify or update the majority of the design and manufacturing specifications/links.
Amartya – I’ve touched up a few of items here. Couple thoughts:
1. Can we add an additional photo? The primary one is perfect, but another (perhaps in an urban environment) would be helpful.
2. Add links to each of the products int he competitive landscape.
3. Target Users: Is/are there better terms to use? (Public/Insitutional/Commercial)… and can we link an article that states this?
