Quiet Revolution’s QR5 addresses wind turbine issues
With the benefits of Windmills come common concerns like the whooshing sound that regular turbines produce, as well as their divisive visual aesthetics. Keeping in mind the volatility of the speed of wind in the urban environment, the QR (Quiet Revolution) has been designed. A new type of wind turbine intended to address both of these issues, Quiet Revolution’s QR5 Vertical Axis Wind Turbine, or VAWT for shawt, is smaller, quieter, and way better looking than your typical windmill, plus it should produce the equivalent of its £25,000 price tag in clean energy within 15 years or less. The elegant helical (twisted) design of QR ensures a robust performance even in turbulent winds. It is also responsible for virtually eliminating noise and vibration.
At five meters high and three meters in diameter, it is compact and easy to integrate, and with just one moving part, maintenance can be limited to an annual inspection.Though the energy output will vary according to the wind speed but is likely to be between 6,000 and 10,000 kWhrs on a typical site. And if that wasn’t all, according the usage of such windmills will also lead to reduction in CO2 emissions. Via

Though this is a step ahead towards optimum utilization of natural resources, it has its respective loop-holes. Automatic switching may lead in wastage of accumulated energy when not required. Besides this, it also requires a battery to store solar energy to reserve all the power for illuminating the nights followed by cloudy days. Also such a solar guzzling shade can be utilized to power up few household gadgets. Like a flower opens to the sun, this device opens at daylight and closes at dusk. This is eco product and showing best unique conceptual high advance future and this eco product is more expensive and generally utilize on home decoration, but that is representing more advance future for another related product, I like this looking good product.
After an array of solar windows flourished in the solar market, new transparent photovoltaic-glass windows from Rainbow Solar are here to make their mark. In a recent study done by the NTUST (National Taiwan University of Science and Technology), the windows have proven their efficiency through energy savings of about 50%. Now, that seems a practical option!
