There is provided a magnesium alloy containing mass percent Al: 5% to 7%, Ca: 2% to 4%, Mn: 0. The unit cell includes a wafer substrate, a layer of micro-electromechanical drive circuitry deposited on the wafer substrate, and an interlayer dielectric deposited on the drive circuitry layer. For each frame in a given scene, a local white level and a local black level are determined from the distribution of pixel luminance values in the frame. Two semi-clyindrical bushings or one cylindrical bushing may be mounted in each aperature. The process involves non-oxidative pyrolysis to recover fluid energy values, oxidative combustion to recover energy values as recoverable heat, and environmental sequestration of gases produced.
