Abstract: A method of manufacturing a building material includes the steps of directing molten volcanic magma from an underwater volcanic magna vent to a level above seal level via a tube formed from the magma, directing the molten volcanic magma into a mold located on a floating barge or located on land, and cooling the magma in the mold to form a building material. As an alternative to obtaining the magma from an underwater vent, the molten volcanic magma can be obtained from a vent on land, a lava pool or stream, tapping a lava tube, or the like. The molten volcanic magma can be cast, molded, formed, extruded, flossed, stranded, foamed and used as a heat source to produce harbor works, floors, walls, roofs, pipe, flotation, barges, vessels, insulation, fiber reinforcing and electricity.

Abstract: A method of manufacturing a building material includes the steps of directing molten volcanic magma from an underwater volcanic magma vent to a level above sea level via a tube formed from the magma; directing the molten volcanic magma into a mold on a floating barge; cooling the magma in the mold to form a building material; and removing the building material from the mold. The tube is formed by lowering a cap assembly over an underwater flowing volcanic magma vent and raising the cap such that the magam solidifies inside the cap perimeter where it is cold.

Abstract: This invention concerns a method for forming thinwall structures from fiberglass, ferrocement or similiar materials in shapes that are inherently optimum in cost-strength effectiveness. Reinforcing means are hung from elevated points forming a catenary surface and then saturated with a post setting material. The structure is inverted after it is stable onto mirror image supports causing its elements to be in compression with negligible bending or tensile stresses.
