ABSTRACT:
A windmill driven electric generator is described with an air sealed closed chamber surrounding rotating and stationary parts to prevent condensation problems during times when the windmill is standing still due to a lack of wind. The closed chamber may be provided with a super atmospheric pressure to avoid entry of moisture-laden air. An air drier is used to maintain the closed chamber air dry and at a temperature that is below the dew point. Various embodiments are described.
