MINERAL ACCRETION OF LARGE SURFACE STRUCTURES, BUILDING COMPONENTS AND ELEMENTS ABSTRACT / By establishing a direct electrical current between electrodes in an electrolyte like seawater, calcium carbon- ates, magnesium hydroxides, and hydrogen are produced at the cathode, while at the anode, oxygen and chlorine are pro- duced. The electrodeposition of minerals is utilized to con- struct large surface area (i.e. greater than 100 square feet) structures, building components and elements of a hard, strong material (i.e. 1000-8000 P.S.I. compression strength). To make a large surface area structure, building component or element of hard, strong material, a preshaped form of electrically conductive material is disposed in a volume of electrolyte, such as seawater, to serve as a cathode, one or more are anodes disposed in proximity to the form, and a direct electrical current is established between the elec- trodes for a period of time sufficient to accrete a solid covering of material on the form.
