In part by circulating cooler water to the surface, this system seeks to reduce evaporation in large bodies of water, such as reservoirs.

Making quieter windmills

Tuesday, December 2nd, 2008

When the greater majority of windmills are located at remote and often desolate locations, noise is hardly an issue.  When installation of windmills is contemplated for suburban and even urban locations, however, noise becomes an important consideration.

Today the United States Patent Office issued yet another windmill related patent to General Electric Corporation.  In this patent, a wind turbine is proposed which has a rigid “acoustic flap”, which extends outwardly from the trailing edge of the blade body.  The distal end of the acoustic flap is smooth and continuous, and results in a reduction of the acoustic noise generated by the blade in use.
