Back in December and March I wrote about the proposal for a new IEA Task on Quiet Wind Turbine Technology. It was approved by the IEA Wind ExCo at ExCo 78 in Brussels on December 1st 2016. The new task has several confirmed participants from leading organisations with others in discussions to join.
The approved proposal can be found here.
Since the last update, John McCann of SEAI has taken on the job of leading this task. If you are interested in participating, please contact him directly. You can find his contact details - listed for Ireland - in the IEA Wind ExCo directory.
