NOVELTY - The device (100) has a heat resistant enclosure (100a) comprising a bottom hemisphere encasing (102) with a cavity for receiving a part of a heat receiving element (HRE) (105) such that a part of a heat sink (107) is in direct contact with the bottom hemisphere encasing. Vacuum (201) is generated in a space within the heat resistant enclosure between a part of a heat receiving surface (106) and a transparent top hemisphere encasing (101). Solar energy is transmitted to the surface through the transparent top hemisphere encasing and transferred through the HRE to the heat sink.    USE - Evacuated solar thermal conductive device i.e. photonic heat sink (PHS), for use in a sun-facing facade of a structure (claimed) of a building.    ADVANTAGE - The device can be designed in small size, so that a single installer installs an entire array of conductive devices without specialized tools or a lifting equipment. The conductive devices can be modified in size, shape, color and/or aperture to serve as a functional and aesthetically pleasing building facade. The device can be easily aligned, placed and removed for maintenance or installation purposes. The heat sink can be utilized without need for a heat pipe or heat exchanger, thus simplifying manufacture of the device and reducing manufacturing cost and complexity of the device. The device utilizes a glass-to-glass seal in the enclosure so as to improve longevity of internal vacuum and to easily produce glass-to-glass seals. The device alters shape of the HRE, so that a large portion of the housing with respect to the HRE ensures a large ratio of surface area for receiving the solar energy relative to the space required to install the device. The top hemisphere encasing has a dome-like shape so as to allow sunlight into the enclosure from a wide range of angles and at various latitudes of the equator. The top outer edge of the HRE does not extend laterally beyond a circumference of the bottom hemisphere encasing, thus avoiding difficulty of manufacturing during the creation of vacuum within the interior of enclosure. The vacuum persists around the HRE so as to prevent unwanted heat loss to a cooler ambient environment. The device utilizes protrusion to attach the device to or through a building wall/facade, or directly into a heat exchanging manifold, thus reducing mechanical load on the device and eliminating the need for a separate attachment. The device enables layer of material with diminished heat conduction properties to be interposed between the HRE and the bottom hemisphere encasing, thus reducing an amount of heat that reaches the seal, and hence increasing efficiency of the device.    DETAILED DESCRIPTION - The encasings are made of heat resistant glass. The HRE contains a conductivity enhancing material that is selected from a group consisting of gas, liquid, polymer and thermoplastic plasma. An INDEPENDENT CLAIM is also included for a method for making an evacuated solar thermal conductive device.
