ABSTRACT:
A wind turbine is arranged to provide for a front torroidal plate mounted from and spaced relative to a rear solid plate coaxially securing a deflecting cone coextensively and coaxially between the front and rear plate, with a series of equally spaced arcuate impeller blades mounted adjacent a periphery of the front and rear plates exteriorly of the cone to direct air flow through the turbine plates from the cone structure. The impeller also has a fluidic rotation indicator. The indicator is a set of arcuate liquid chambers which contain two different fluids of different colors and specific gravities. When the impeller is stationary, the two different fluids separate, indicating two colors. However, when the impeller rotates, the two fluids mix and indicate a single third color.
