Abstract: Concepts and technologies described herein provide for a cost-effective method and system for installing a solar array without utilizing a concrete foundation that supports a mast. According to various aspects, a solar array is attached to a helical anchor via a solar tracking mechanism. The helical anchor is a one-piece apparatus that is screwed into the ground so that the helical anchor includes an above-ground portion for connection to the solar array, and an underground portion that provides the foundation for supporting the solar array. The specific configuration of the helical anchor and a corresponding helical anchor blade may be selected according to soil and environmental characteristics associated with the installation location.

Abstract: A method, device and composition for achieving ignition and sustained combustion using a solid consumable catalytic bed (CCB) is described. The CCB accomplishes this by decomposition of an injected fluid. Initially this reaction is catalytic or hypergolic in nature, eventually becoming entirely thermal as the CCB is consumed in the reaction generated. The CCB may be placed in a hybrid motor system such that the decomposed injected fluid will undergo combustion with the solid grain. When the injected fluid is high concentration hydrogen peroxide the catalytic materials of construction for the CCB are selected from the metallic hydride family, the manganese oxide family and the cuprocyanide family.
