The search for renewable sources of energy and the technologies to harness them is going on worldwide. One such project underway in the UK is quietrevolution ltd, who is developing a small wind turbine for the urban environment that is quiet, efficient and pleasing to the architectural eye.
Urban, or built-up environments, create wind turbulence which can negatively effect a wind turbine’s performance. The ubiquitous horizontal axis, propeller-type turbines can have their efficiency greatly reduced by changes in wind direction and turbulence. This is a primary reason for opting for a vertical axis wind turbine, a design that doesn’t require physically rotating into the wind every time wind direction changes, wasting valuable energy.
Using real wind data, the designers of the QR5 have shown that it produces 20% – 40% more energy than a conventional, similar-sized, horizontal wind turbine, in a typical urban location — near buildings or where the wind is turbulent.
This technology and design appear to have great potential.

Your product sounds great. I live in Bryant, Indiana USA. Our county, Jay County, is considering putting up a big wind farm with the 200 ft high hugh propellers. I also live near Amish who have windmills for water. I think your wind turbines would be better on individual properties, but the cost is prohibitive for individuals. Is there anyway my home could be an experimental site in the USA?
I am an ecologist and have a number of projects involving the effects of small turbines on bats. Can you tell me if your turbines create a drop in air pressure which appears to be causing problems for bats in America whereby they are dying from barotrauma which essentially means that the lungs are collapsing due the steep fall off in air pressure close to turbines. Research to date appears to be only concerned with large turbines.
Thanks
