The new 'Architecture Wind' system is highly efficient, features a bird shield, and looks stylish atop urban roofs.  (Source: Aerovironment)

While some wind power may just blow, Aerovironment looks to be sleek and stylish

Wind power is an oft maligned source of alternative energy.  One common complaint aired is that it’s not cost/resource effective.  On a similar track, people often accuse it of producing too little power to be helpful.  Finally, some accuse it of being too obtrusive.  Even some environmentalists knock wind power for allegedly killing birds that fly into the slowly spinning metal turbine blade.

While it can't change such opinions overnight, Aerovironment is looking to slowly warm people to wind power by providing direct solutions to the frequent criticisms. And in the process, it hopes to transform the face of modern cities around the world.

Aerovironment produces building-mounted turbines, smaller than those typically seen on wind farms.  By mounting the turbine structure to the tops of buildings, the benefits are twofold.  First, the cost in resources of building a pole to support the turbine is eliminated.  Secondly, the turbines can be elevated much higher, exposing them to stronger winds.

The nearly silent turbines snap onto the parapet of urban structures, forming a design that Aerovironment calls ‘Architectural Wind’.  The rows of turbines not only catch cross currents, but also the frequent currents that develop up the side of buildings.  The result is a 30 percent increase in energy production and even better, a great savings in hassle, in that the turbines are quick to snap in.

While the system is extremely well designed and efficient, many will be drawn to its style.  The system's curvy design looks more like a modern art sculpture than a cutting edge alternative energy design.  This in turn adds to the urban appeal.  Part of the structure even serves another utilitarian use -- the large metal plate over the turbine acts as a bird shield, in an effort to minimize avian casualties.

Aerovironment describes their product stating, "Architectural Wind is designed to install easily onto the building parapet, operating in plain sight as an attractive complement to the building’s architecture. Additionally, based on its proprietary system design, Architectural Wind turbines rotate at low wind speeds, resulting in a form of ‘kinetic architecture’ that communicates clearly the generation of clean energy. Working alone or in tandem with other renewable energy technologies, Architectural Wind is designed to offer an attractive ROI and cost per kW of installed capacity."

A module weighs 200 lbs, allowing relatively easy installation, but also ensuring that it won't blow away.  They measure 4 feet tall by 4 feet wide.  Installations start at 6 kW of power production and can be scaled up to produce much more.  Almost any rooftop is suitable to the nonintrusive installation.  The product is in development, but the company hopes to mass produce the new turbines on a large scale, making them relatively affordable, and ensuring the systems turn a profit in energy costs.

While wind farms leave some with little to be excited about, Aerovironment's new approach seems an intriguing fit to bring wind power to an urban atmosphere and start cutting costs.

However, with food prices rising every day due to the silly ethanol-subsidies, the inclusion of a bird-shield is ludicrous.

I know your being sarcastic, but the "bird shield" is mainly there to catch thermal flow up the side of the building and give it a decent velocity component across the fan blade.

oh absolutely - it would serve to increase volume considerably which I am sure is the primary intention.

I suppose they could put a bird feeder in front of the fan and a jumbo sized bucket in the back. ;) Once they are on the feeder there would be no escape. If they try to fly away they'll bump their heads and... oh... That's the sound of more fresh food on the way!

I think that would be a fair compromise. I'm hungry darn it.

THWAK! Bird soup.

I dont think it will be long before they have to include some sort of cage to prevent birds from getting blended flying into them.
