The electrical energy generating system of the present invention comprises a piece of alignment Buckypaper, an energy generator, a thin deposition and two contacts. The alignment Buckypaper is a thin sheet made from an aggregate of carbon nanotubes. The thin deposition is formed on at least one surface of the alignment Buckypaper by electrolysis to form a semimetal material. A contact is connected with the upper surface of the alignment Buckypaper and the other contact is connected with the lower surface of the alignment Buckypaper. In use, the energy generated by the generator is inputted to the alignment Buckypaper. The energy then ionizes the molecules contained in the alignment Buckypaper. The positive charges move to the upper contact and the negative charges move to the lower contact. Such electrical energy may then be fed to a load connected with the two contacts to do work on the load.
