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

The big news is – Google decides to go green. In an attempt to rescue the USA from the energy crisis before 2030, the largest search engine in the world has decided to pursue a new energy plan. Experts believe that the company is being a little too modest calling their effort as too small, when now they are supporting and 's green technology like wind power, solar energy, geothermal energy etc like never before.
Green activists have taken up cudgels against Starbucks now. The coffee-giant that boasted of Eco-friendly credentials came under the scanner when investigations by Sun revealed that everyday 23.4m liters of water goes down the drains of 10,000 outlets worldwide due to a company policy that tells the employees to keep the tap running non-stop. Facts show that this much water is enough for the 2 million population of the drough-ridden Namibia to survive for a day.
You can turn pee into water with a special kind of machine. As insane as it sounds, the trick has been performed by inventor Dean Kamen. Already a big name in the world of water filtration, Kamen has again gathered a lot of attention thanks to the Slingshot machine he has created.
We keep hearing about Eco-friendly vehicles dominating the roads across the world. But Mochi Craft has thought about the remaining 71%, which is water. A branch of Ferrety Group, this organization sailed in world’s first Eco-vessel.
A hybrid yatch and this was launch at 48th Salone Nautico Internazaionale and this green tag come from hybrid force scheme that is wholly designed by Ferrety. And I think I want to say this is a twin MAN diesel inboards are friendly to a 15-inch, touch screen monitoring system; thus allowing the helmsman to be able to switch among three different propulsion modes with the swipe of a finger: diesel, diesel-electric, or just electric.
An amazing start indeed, because once such eco-friendly hybrid yatch sail across the blue water the ever-increasing pollution level will come down. Plus with its diesel-engine combination, the 75-feet water bus leave’s ten kilograms of carbon dioxide for each nautical mile. There is also a battery pack that too can power the boat. And in this diesel-electric mode, the vessel emits less than half a kilogram each nautical mile. The RINA Green Star certifies that the Long Range 23, priced at a huge three million euros comes with both enhanced hydrodynamic capability and static stability, really very cool product.
