Abstract: A portable thermal collector and storage apparatus is disclosed as comprising a container for receiving a phase change material for selectively absorbing and emitting thermal energy, a base for supporting the phase change container with respect to a floor surface, and a set of wheels or rollers mounted on the base for facilitating the movement of the base and the phase change container from a first, thermal absorbing location to a second, thermal emitting location. In a further aspect of this invention, the thermal collector and storage apparatus includes a tabletop for receiving and supporting the phase change container. The tabletop includes a plate for presenting a table surface, and is made of a material transmissive to solar radiation, whereby solar radiation may be directed through the plate and onto the phase change container.
