A new mechanism for superconductivity, based on the pairing of spatially separated electrons and holes that arises from their Coulomb attraction, is proposed. A gap in the single-particle excitation spectrum is found. The roles of interband transitions, the electron-phonon interaction, scattering by impurities, spin-orbit interaction, etc. are analyzed. The critical current is calculated. Possible experiments are discussed.
