Airstream is extremely quiet and makes a small amount of operating sound similar to the level of a small office. It generally cannot be heard over typical background noise such as the sound of the wind. Airstream does not interfere with TV reception.
Is Airstream dangerous to birds?
While no formal studies have been done, anecdotal evidence indicates that birds occasionally collide with small wind generators as they do with any other type of structure. However, such events are very rare.
Should my neighbors be concerned about safety if I get a Airstream?
No. Airstream's design and testing was done to internationally accepted standards for small wind safety and reliability. Your neighbors who may have some concerns about safety may appreciate the following information:
Tower stability: Thousands of small wind generators are installed every year and their safety track record is excellent. Trees are much more likely to fall than a properly installed Airstream, but no setbacks or minimum property sizes are required for trees.
Safety of utility repair personnel during a power outage: In accordance to IEEE and UL, Airstream will automatically shut down in the event of a power outage, and will not energize a dead power line. This is necessary to protect the utility line repair person.
Will a Airstream damage neighboring property values?
No. With thousands of small wind generators installed today there has never been any evidence to support this claim.
Will my local government allow me to install a Airstream?
YES.
Will I have to change any of the wiring in my house?
No. Airstream can easily be installed at any existing home without the need to change any wiring or appliances.
What about towers?
Towers as short as 10 feet are available with Airstream. However in some circumstances, a taller tower may be necessary to raise the generator above turbulence created by obstacles on the ground and/or trees. Wind speed increases with height above ground, and increasing speed increases the amount of energy your generator will produce. Relatively small investments in increased tower height can yield high rates of return in energy production.
A rule of thumb for proper and efficient operation of a Airstream suggests that the generator should be 20 feet (6 meters) above the top of anything within 150 feet (about 50 meters).
