The result is a turbine that’s 50 percent less expensive than a bladed one, nearly silent, and, as one of the turbine’s engineers put it, “looks like asparagus” And while each Vortex turbine is also 30 percent less efficient at capturing energy, wind farms can double the number of turbines that occupy a given area if they go bladeless.
I doubt this style of wind turbine kills raptors and other birds flying in the area too.
