Professor Alexander H. Slocum ’82 presents his research on energy storage to United States President Barack Obama. Slocum explains a system for harnessing excess wind energy. When the wind is not blowing, water flowing into the storage area through a turbine produces electricity. When the wind is blowing, excess power is used to pump water out of the storage area.
