We normally think of early wind power as a means of pumping water, but in the 1920's and 1930's people often built home made "Wind Chargers". These were early devices to bring a little electricity to a home before electricity was available from the utility companies. They systems typically worked like this. A home made wind mill was connected to a car generator. As the wind blew, the generator turned, and charged a battery. The system typically had two batteries . . . one inside being used, and one outside being charged. The batteries would be swapped about once a day. The car battery would be enough to run a radio, and provide a little night time light. A pretty crude system, but much better than no electricity at all.
