This invention is related to a transparent glass tube evacuated from air and other gases. To prevent the transferring of heat. This glass tube contains reflective mirrors that focus on the sun rays, the shape of these mirrors are (parabola). The evacuated glass tube also contains liquid carrier made of metal or glass that goes through this parabola so that the sun rays focus on it. This liquid carrier tube is coated with absorbent coatings of sun rays. Any liquid substance transferring heat, such as oil goes through this liquid carrier tube. These evacuated glass tubes can be used individually or placed in rows on a metal holder and moved according to the movement of the sun. So that the parabola mirrors are directed towards the sun then the solar rays focus on all sides of the liquid carrier tube. Then the oil will become hot and goes wherever place which it can be useful in heating the steam turbine boilers and heating swimming pools and in factories. These tubes are made in different sizes, diameters and lengths as needed, and their size is proportional to the size of the reflective mirrors and the liquid carrier tube, FIG. 1.

A system includes an evacuated tube solar adsorption heat pump (ETSAHP) module. The ETSAHP module includes a transparent or semi-transparent tube configured to receive heat input from solar energy, the tube having a hollow interior, a top section, and a bottom section opposite the top section, an adsorbent bed comprising a plurality of adsorbent beads and positioned at the top section of the tube and configured to absorb solar energy, an adsorbent bed cage configured to contain the adsorbent bed at the top section of the tube, a threshold configured to stabilize the adsorbent container within the tube, and a condenser/evaporator positioned at the bottom section of the tube and spaced apart from the adsorbent bed.

The invention relates to a small solar cooker with thermal energy storage. The device comprises an insulated wall (11), a transparent surface (1), and a Fresnel lens (2). The focal length of the lens can be adjusted using an automatic mechanical system (3) (12) to follow the height of the sun. During pre-heating, the focal point (10) of the lens is located on a small copper reservoir (4) containing a phase-change material (6). This material is thermally recharged by two methods: the concentration of radiation by the lens and/or by an auxiliary resistor supplied by an alternating current (5). The heat accumulated in the small reservoir allows the oven to be used when the sun is not shining or to reduce the cooking time. The whole oven is linked to another automatic mechanical system to follow the path of the sun.

The present invention provides a solar energy collecting and converting system comprising a plurality of segmented reflective elements such as mirrors forming a trough shape structure. These reflective elements are attached to the glass top of a metal box. The solar cells are placed at the bottom of the box and heat sinks are placed underneath the solar cells. Further, the segmented reflective mirrors are attached to a rod at the bottom for additional support. In a variation of the system, the solar cells are replaced with an insulated container comprising light absorbing material at the bottom of the panel. A glass window on the top of insulated container lets the solar light pass through and heat the light absorbing material. The small size of the window does not let the heat radiate from the insulated container through the window and improves the performance of the whole system.
