A building with ultra-stable cementitious material with nano-molecular veneer has 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material, 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, a phosphorus-containing material, and wherein the mixture forms a liquid suspension that reacts into an amorphous phase cementitious material, wherein a portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals are encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer and a wall material that is affixed to a frame of a building.

A photovoltaic power source includes a receptacle to receive a photofuel including a liquid, and one or more photovoltaic cells positioned within the receptacle to receive light emitted from the photofuel when the photofuel is in the receptacle. The photovoltaic power source also includes power circuitry coupled to the one or more photovoltaic cells to receive a photocurrent generated by the one or more photovoltaic cells when the one or more photovoltaic cells receive the light emitted from the photofuel. In response to the photocurrent, the power circuitry is coupled to output electricity.

An ultrastable cementitious material with nano-molecular veneer makes a cementitious material by blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material, with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material, wherein a portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals are encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer. A process to make the ultrastable cementitious material. A tile backer board incorporating the ulstrastable cementitious material and a process for making the tile backer board.

Light-weight, fire-resistant mineral foam includes an inorganic cementitious matrix and at least one metal hydrate that is a super hydrate substance, in which water is present with the substance in an amount of at least about ten moieties of water of hydration per formula unit of the substance. As a cured solid, that mineral foam, or another mineral foam composition including an inorganic cementitious matrix, can be provided as a structural member in part of an assembly that has at least one open web, thermally insulating support member at least partially embedded in the cured solid. Also, the cured mineral foam may be a solid foam in a form of a panel, panel block or tile, which may have a tongue provision and/or a groove provision.
