Abstract

An accretion disk surrounding a supermassive black hole at the active galactic nuclei radiates tremendous energy. In order to utilize energy of the accretion disk system, the author investigates the configuration and stability of a floating platform - photon floater - above the accretion disk, which is supported by the radiation pressure of the disk radiation. In the case of the far-floater, which is located far from the disk, there exists a critical floating angle, where the gravitational force of the central black hole is balanced with radiation pressure. In the case of the near-floater, which is located very close to the disk, there exists a critical floating height, where the gravity is balanced with radiation. It is demonstrated that this floating height is dynamical stable. Finally, in the case of the axis-floater, which is located on the axis of the disk, the photon floater is unstable.
