Gerard Andlauer, IP 5 rue de Castelnau Mundolsheim 67450 France The Infrared Alternative The satellite structure consists in a three-pointed star that rotates on itself while it turns around the planet so as to train ever the same axis to a district on the Earth where the ground receptor structure is located. The branches of the star are parallelepipeds 1 kilometre in length and width and 100 metres broad that intersect at 120° in the focus of a triple hyperboloid. These define a lattice of pipes as cubes of 10 metres edge. The external "peel" is ordered in panels of polymethacrylate and glass fibers of 1 square metre size. The inter-r face of them is blackened in order to absorb the incident solar radiation and reemit it on the inside at a far infrared that cannot traverse the coat panels: the general structure is acting as an orbital green house. The infrared is trapped and focalised along the axis that faces toward the ground receptive structure. It traverses at the end a screen of filtering panels on an interference principle that retain the wavelengths such as to be absorbed during the path in the Earth atmosphere particularly through the H2O molecules. They only let out the wavelengths that coincide with optical apertures so as the 3.8, 8.5 or 10.6 microns gaps. The emergent beam will avoid any loss of energy due to absorption or diffusion in the atmosphere before it reaches the ground receptive surface.
