Nearly 30 percent smaller than conventional turbines, the AeroCam features breakthrough turbine technology that easily adapts to changes in wind direction and extremes of wind speed. Thus, the AeroCam can easily handle highly turbulent environments that are problematic for conventional horizontal axis wind turbines.

From 10 KW to 500 KW systems, operational from 4 to 80 MPH. Urban to Distributed and Infill locations.

Their first beta units are expected to begin deployment in November 2008. Commercial installations for buildings is expected to begin in March '09, at which point they expect to be able to produce several hundred per month. Their first target will be industrial, followed two to three years later by residential applications. One of the aspects that makes them able to compete with existing wind farms, is that it is much easier to ship and assemble their units. The largest components can be fit in 20-foot shipping containers.

The scalability and ease of installation enables them to "bring wind closer to the point of use."

Because the turbine does not spin much faster than the wind speed, bird casualties will not be as great as with the traditional horizontal axis bladed systems.

Interview

Download (13 Mb, mp3) - On June 30, 2008, Congress:Founder:Sterling D. Allan conducted a 1-hour, live interview with Steve Else, CEO, as part of the Free Energy Now radio show.

How it Works

The new design is based on principles first established by the French aeronautical engineer There was an error working with the wiki: Code[1] (1888-1979), who invented a wind turbine capable of operating from any direction and under adverse weather conditions. Darrieus machines typically have a vertical axis, whereas the AeroCam design has a horizontal axis with multiple blades, giving it the appearance of a water wheel.

The major innovation in the design, according to BroadStar, is the ability to automatically and interactively adjust the pitch of the aerodynamic blades as the turbine rotates, thereby optimizing its performance.

Costs

BroadStar’s technical achievement delivers a 250kW machine for $250,000 and is the first to break through the $1/watt cost barrier, which is unprecedented in the industry. Previously, the best that could be achieved in the U.S. was $1.38 and in Europe $2 of capital investment for every watt of power capacity installed.

Advantages

Markets

20%+ more power than conventional fixed blade designs

Exceptionally wide operating range ~ 4 – 80+ MPH

Can be deployed where conventional turbines cannot

Slow rotation speed

May be placed in turbulent environments

The patented design features aerodynamic blades that use the natural flow of air to create lift, and an offset cam that allows the blades to continually adjust for optimal pitch throughout a

360-degree rotation of the turbine. As a result, the AeroCam is approximately 30 percent smaller yet generates the same power when compared to conventional horizontal axis wind turbines (HAWTs).

Applications

“The efficient aerodynamic design lends itself to smaller wind turbines, which can operate closer to the ground or on a rooftop. They can handle a wide range of wind velocities, anywhere between 4 and 80 mph. They generate their power at lower rotational speed, so there is less noise and vibration hence less wear and tear. But most importantly the AeroCam can be manufactured at a lower cost than conventional turbines.?

One of the early adaptations will be commercial building roof edges where the wind is concentrated by the building.

Residential applications will probably be three to four years away.

Independent Testing

(As of June 9, 2008)

"We have two units operating in the field. One at West Texas A&M in Canyon, TX and the one we had at the show... which is on its way to WTA&M for field testing. We have components ordered for about 40 more units. We will deploying these units in demonstration projects throughout the country. Our plan is to work into full scale production and full scale market entry over the next 12 to 18 months." Keith Bass.

The company completed CFD analysis in around June of 2008.
