Abstract: A large cylindrically-shaped balloon-like structure having hemispherical ends with fins utilized in conjunction with airflow thereacross based upon Bernoulli's principle for maneuvering and maintaining stability. The balloon is compartmentalized, contains a uniquely designed structural support system, and contains pumps for evacuating the air therein. The structure may be used for any lifting application. In particular solar-energy is collected through a transparent portion of the structure and reflected from shaped surfaces that direct solar energy on energy converting panels. The electrical energy generated is utilized to operate an evacuation system, while the remainder of the electrical energy is beamed by microwaves to a receiving station on earth.

Abstract: A reversible, variably inclinable window with controlled convection for mounting in a window casing in a building for solar heating and cooling comprising a window frame having top and bottom portions and being adapted to pivot about a horizontal axis intermediate said portions, a first window panel mounted in said frame capable of transmitting both visible and infrared radiation, a second window panel mounted in said frame, substantially parallel and in a spaced relationship to said first window panel and being capable of transmitting visible radiation and blocking infrared radiation, and openings proximate to said top and bottom portions for providing air passageways to space between said first and second window panels such that rotation of the assembly about its horizontal axis can place either of the panels toward the outside of the building for selective reflection or absorbtion of the radiant energy to enable heating or cooling of the interior space between the panels in order to utilize the properties

Abstract: A device for the protection of antennas against lightning and electromagnetic pulse consisting of an electrically conducting rotor that is free to turn on a conducting shaft which is connected to the antenna. This combination is placed within an electric coil with one end connected to ground. The rotor is mounted eccentrically within the coil so that when a predetermined critical voltage on the antenna is exceeded electrical current flows through the rotor, and coil to ground via the air gap separating the rotor and coil, a magnetic field is set up in the coil which turns the rotor and reduces the air gap as the voltage is dissipated, after discharge of the surge, the rotor returns to its quiescent position.

Abstract: A system and method for determining the electrical parameters of large samples of materials in situ. A set of linear electrodes in boreholes forms a square pattern; positive and negative electrical potentials on alternate electrodes create symmetry planes which define several "cells"; a given fraction of electrical current leaves an electrode and reaches a corresponding electrode, an impedance characteristic is determined for each cell. The presence of inhomogeneity and anisotropy is reflected by unequal currents in geometrically equivalent cells.
