ABSTRACT:
A frost-resistant windmill is disclosed to provide supplemental power supply for use preferably in large cities. The frame of the windmill carrying a plurality of blades is made hollow defining a serpentine internal air pathway adapted for introduction of warm air from an external source to prevent freezing when used during winter months. A centrifugal speed adjustment system is provided to reduce rotation speed fluctuations of the load drive shaft when strong wind gusts are encountered. A speed adjustment weight is connected to the drive wheel through a cable such that the position of the drive wheel along the radius of the windmill is defined by an equilibrium between the pull force on the cable and the compression force of the spring urging the drive wheel towards the periphery the windmill.
