When considering different wind turbines, it’s important to understand the differences in technologies. Horizontal Axis Wind Turbine (HAWT) technology — traditional, propeller-style turbines — is the most common wind power approach installed today. WindTamer turbines use Diffuser Augmented Wind Turbine (DAWT) technology, and improve upon traditional technology.

WindTamer Turbines (DAWT) |
WindTamer Benefits |
| Typically require 120-foot towers | Require a pole that’s 20 feet tall or less | Complies with most zoning laws |
| Require an acre of land | Require 10 square feet; can be installed near buildings and on rooftops | Can be used in residential areas |
| Exposed blades kill thousands of birds | Housed blades; birds perceive the turbine as a solid object | Safe for birds |
| Noisy operation | Silent operation | Neighbor friendly; no trouble with noise ordinances |
| High vibration; cannot be mounted on rooftops | Low vibration; can be mounted on rooftops | New places for wind energy |
| Complicated installation – tower purchased separately from turbine | Streamlined installation that includes tower | Greater convenience |
| Safety risks from thrown blades and ice | Housed blades eliminate risk of thrown blades and ice | Safe operation allows placement closer to general population |
| UV rays and weather shorten the life of generator and rotor blades | Housed blades protected from UV and weather | Lower maintenance costs and less downtime |
