摘要
The instant invention comprises a method for freely suspending without any solid material support, a platform in an atmosphere by atmospheric- particle-momentum transfer having opposite surface portions which are structured to have different atmospheric-particle-momentum- transfer characteristics determined by temperature and surface structure. Electromagnetic radiation is transmitted from an antenna with the platform disposed in the atmosphere so that the radiation impinges the platform. A temperature difference between at least one surface portion of the platform and the atmosphere adjacent that surface portion is established by regulating the temperature distribution on the surface of the platform by heating at least one surface portion by the impinging radiation. The net force produced on the platform freely suspends the platform in the atmosphere. The center of mass of the platform is located below the point of attack of the resultant force generated by the net atmospheric particle momentum transfer and the altitude is controlled by varying the intensity of the radiation impinging the platform. The platform surface structure includes, on one surface, indentations which increase the average number of particle collisions as compared to the structure on the other surface. The platform may be in the form of an inverted dish with a stabilizing weight, the dish may be solid or formed of generally intersecting ribbons. Further, the structure between opposite surfaces of the platform may include insulation or materials producing resonance between the layers by the impinging radiation.
