Advantages of 5-blade wind turbines over 3-blade wind turbines
1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions. For areas with average wind speeds of 11 MPH (5m/s). If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%.
2) 5-blade wind turbines will dramatically improve the reliability and safety in high speed wind conditions. The blade rotation speed of a 5-blade turbine is 60% of the rotational speed for a 3-blade wind turbine. 5-blade wind turbines will greatly reduce chance of overspeed control malfunction. This will ensure operational reliability from a long term perspective.
3) The lower blade rotation speed of 5-blade wind turbine will lower wind turbine noise and make 5-blade wind turbines more community friendly than 3-blade wind turbines.

Ambient Weather WS-1090 Wireless Home Weather Station w/ Data Logging & Atomic Time
The Ambient WS-1090 is a compact, easy to install complete wireless (915 MHz) home weather station with impressive reliability at a very low cost. The WS-1090 weather station measures wind speed, wind direction, temperature and humidity (both inside and outside), rainfall and barometric pressure, and calculates dew point and wind chill. The weather station's touch screen console displays a wide range of parameters in an easy-to-read format on a large LCD. The attractively thin console can be placed on a desktop or mounted to a wall. The console archives 4080 historical records and can be reviewed with a touch of the back lit console. Includes a USB port and EasyWeather PC software (free PC web publishing software available, including Wunderground hosting services). The sensor suite is integrated, with 8 foot interconnecting cables between the anemometer, rain gauge and wireless thermo-hygrometer-transmitter. Specifications: Outdoor temperature range: -40°F to +149°F Indoor te | ||
