The windsock horizontal axes windmill is much like a conventional horizontal axes windmill with two unique differences. The propeller is replaced with a cone shaped turbine that runs slower with less noise very much like a squirrel cage type vertical axes windmill. The cone shaped turbine can also be seen so birds don't fly into it. The windsock turbine used underwater has the same advantages and also has the advantage of deflecting seaweed and other garbage pass the turbine because of the cone shape with the point facing the oncoming water. The windsock acts like a weedless, environmentally friendly prop in the water.
