An Australian company called Renewable Energy Solutions Australia Holdings Ltd. (RESA) has created what it says is a super quiet and efficient wind energy turbine.
Suggestively called Eco Whisper, the wind turbine employs 30 smaller ones capped with a specially designed cowl ring that keeps them silent in most meteorological conditions. A cone shape allows the blades to automatically rotate into the direction of the wind, with no need for a heavy tail structure.
Besides being more silent, the blades are more efficient, too. RESA says the turbines increase efficiency by 30 per cent at average wind speeds, and will keep rotating even when winds are very slow.
.20kW horizontal axis wind turbine
.Virtually silent operation
.6.5m blade diameter
.30 blades extending outwards
.Dynamic slew drive
.Solid, lightweight structure
.High performance in all wind conditions
The manufacturer says EcoWhisper is suitable for commercial, manufacturing and industrial sites, airports, ports, mining resource facilities, council sites and industrial development sites. It can also be installed on shopping centres, industrial parks, schools, universities and others. Off grid rural communities could also benefit.
It sounds like an exciting new development in wind turbine design!
