10,000 kW Electrical Power Generation in Your Backyard
Posted by: mpg in Environment, Home & Garden
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.

10,000 kW? Over what period of time? Or is it continuous power at a certain wind velocity?

Costs twice as much as a horiz. axis unit, with the SAME output?? I don’t think so! I’ll buy a horiz. axis unit and just put Christmas lights on it.

LED lights I imagine.

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.

Since the horizontal axis turbines change direction automatically when the wind switches, this vertical axis system’s lack of directionality is therefore not much of a technical advantage.
However it is a very beautiful and elegant design. If it is quieter than conventional units, this is an important innovation.
I hope they sell plans or kits or license the design to bring the costs down quickly and facilitate adoption.

Correction - it COULD BE a technical advantage if they were to translate the design simplicity of the system’s nondirectionality into a cost savings over a horizontal axis system of similar output. But so far, the opposite remains true.

it is absurd actually. 1.4Mw per day is about 10 of the highest efficiancy solar panels. Anyone who really knows about living off grid will tell you, YOU DON’T WANT TO LIVE IN A PLACE that you can live off of wind power. When the current advances in Solar bring the efficiancies up to about 35-45% (non silicon based thin film technology and the introduction of nano science into the mix, have great potential).

Man that is so awesome. Check out my awesome electronics review blog at http://electronix-review.blogspot.com. Also if you are a southpark fan I have a blog with all the southpark episodes free to view! http://allabout-sp.blogspot.com THanks!

Don’t worry about birds: More birds die per year by colliding with airplanes than they do by getting chopped up by wind turbines. Plus, if the thing’s constantly rotating at any speed, no bird is going to roost there.

That thing looks weird. Looks more like an antenna than a wind turbine to me.
