Efficient frequency spectrum sharing between at least one incumbent communication system and at least one cognitive radio system is provided. The cycle includes a decomposition of a gaseous phase sulfur trioxide to sulfur dioxide and water in a decomposition reactor and an oxidation of gaseous sulfur trioxide with H2O in an electrolyzer to form sulfur trioxide and hydrogen. By this method the Universal Power Strip will increase the electricity from 110-120V to 220-240V and power the 220-240V devices.
