RESA Launch the Echo Whisper, an ultra low noise Wind Turbine
Renewable Energy Solutions Australia (RESA) have completed the commercial installation of the Echo Whisper in Tullamarine, Victoria, Australia after two years of development and testing.
The echo whisper features a unique 30-blade design which provides more surface area to catch the wind than your traditional turbine. This increases the efficiency of the turbine allowing as much as 30% more energy to be generated at lower rotational speeds, which partly reduces the noise produced.
The cowl along the blade tips reduce turbulence at these tips meaning that less power is lost and blade tip noise is reduced as a result.
This highly efficient turbine can operate at wind speeds as low as 1.7 m/s (3.8mph) which is approximately half that of a typical 3 blade turbine and comes in 20Kw and 5Kw models.
