The windmill was used by the early inhabitants of Chellburg Farm to pump ground water from a well. The windmill and pump are both still functional and offer great potential to capture resources with wind and mechanical power. The Nelson Home has a pump shack and a windmill, believed to be exactly like the Chellburg windmill. However, the Nelson windmill is not functional and the pump shack was filled with litter. With some modifications the windmill could be made to harness wind energy for electricity or to power a water system.
