The second, SolarRetrievers,[79] raised an additional $30,000 from UMBC Residential Life, Facilities Management, and The Commons to purchase 4 EnerFusion Solar Power-Dok solar tables. These tables promote the idea of sustainable energy by directly demonstrating how solar panels are used to charge a battery and power devices in areas that normally would not have electricity readily available. The tables are located in the courtyard between Harbor and Chesapeake Hall, The Commons terrace, and two are on the terrace outside of the Retriever Activities Center.
