Abstract: A fire-protection mechanism is described. The fire-protection mechanism includes multiple, overlapping cavities that can be filled with water (and, more generally, a fluid). When the fire-protection mechanism is deployed over an object, such as a building, and the cavities are filled with water, the fire-protection mechanism reduces the likelihood that the object is damaged by the heat associated with a fire proximate to the object, such as a wild fire. In particular, the heat capacity and latent heat of the water significantly increase the thermal time constant of the object, thereby reducing the likelihood of combustion. The fire-protection mechanism may include a reflective coating to redirect infrared radiation away from the object to provide further protection. In addition, the water in the cavities may be refilled, as needed, by directing a stream of water onto the fire-protection mechanism and/or through an internal channel in the fire-protection mechanism.
