Electrical Power Generation in Your Backyard
10,000 kW Electrical Power Generation
in Your Backyard
Want to get off the grid? the Electric grid that is. The QR5, from U.K.-based Quietrevolution, is a residential-scale wind turbine that generates enough electricity to power a standard U.S. home or a small office. It also looks like a piece of wind-powered sculpture. Unlike the shape of a conventional windmill propeller, it’s a Vertical-axis wind turbine. Beneath the skin is what Quietrevolution calls the world’s most efficient turbine for capturing air currents near buildings and other structures, with carbon-fiber blades shaped to grab gusty city winds without making much noise. But make sure your checkbook is fully charged: At $48,000, the QR5 costs twice as much as a traditional propeller-style unit that generates the same output. It’ll take 18 years to pay back your cost.

It’s average output, according to their website, its 10,000 kWh, which is Kilo Watt Hours (not kilowatts). If you supply 1 kilowatt for an hour, its 1 kWh, a measure of energy (not power).
They say 10,000 kWh takes 1 year to produce. There are about 8760 hours in a year, so that’d be 10000 kWh / 8760 hours = 1.14 kW average power output. Thats pretty small for a structure of that size.
I wouldn’t be surprised if the annual energy production could be three or four times as high if it were installed in a consistently windy spot, though. They do need to bring the cost down, though.
As for the horizontal wind generators, well, they are less compact and work best in directional wind, whereas the vertical doesn’t have to be pointed into the wind. That means you can install it at odd locations like the base of mountains, where the winds can be strong, but inconsistent in direction.
