A building has outer envelope that has at least one facade portion which is transparent to solar radiation and that is situated on a face of the building, the shape of at least a part of which can be inscribed inside the surface generated by an imaginary segment extending between the sun and at least one fixed point that is fixed relative to the Earth. Facade portion(s) extend between a base line and a top edge which together delineate it from the remaining part of the outer envelope of the building, which is predominantly or completely opaque. The exterior face of each part of the facade portion is, at each point on the top line, set back from a straight line perpendicular to the local horizontal plane, and therefore normal to the plane of the ground, and passing through this point. At least one of the facade parts can be inscribed inside the surface of a cone frustum part that is recessed or concave relative to the face concerned.

The method is for conveying solar power from a sun. A solar concentrator conveys and concentrates solar power as rays into a cable. The solar concentrator has a tapering device disposed at a bottom thereof. The cable has a first curved glass loop section, a second curved glass loop section and a curved section. The curved glass section is connected to a storage unit wherein the light is converted into heat. The first loop section is rotated relative to the second loop section at a first gap and the second section is rotated relative to the curved section at a second gap so that the concentrator can follow the path of the sun during the day.

A solar automatic heat collecting and equalizing tube, including: a glass tube, an absorption tube, and a baffle. The glass tube is sleeved on the absorption tube. The absorption tube is coated with a heat absorption layer. The space between the glass tube and the absorption tube is vacuum. The baffle is disposed in the inner cavity of the absorption tube and is configured to drive a fluid in the absorption tube to tumble up and down alternately. The baffle is spiral in shape and fixed in the absorption tube.

A method for fabricating a self-aligned via structure includes forming a tri-layer mask on an ILD layer over a lower metal wiring layer, the tri-layer mask includes first and second insulating layers and a metal layer in between the insulating layers; defining a trench pattern through the first insulating layer and metal layer, the trench pattern having a first width; defining a first via pattern in a lithographic mask over the trench pattern, the first via pattern having a second width that is larger than the first width; growing a metal capping layer on an exposed sidewall of the trench pattern to decrease the first width to a third width that defines a second via pattern; transferring the trench pattern into the ILD layer to form a trench; and transferring the second via pattern through the ILD layer and into the metal wiring layer to form a via.

The present application describes an automated structure for reception of modular constructions and respective automation system comprised by a lower structure (1), which contains an opening (4) for accommodation of a fixed shaft, comprised by the element of attachment of the shaft with the exterior, where, preferably, the structure and the fixed shaft of fixation to the exterior (5) can be coupled, a lifting mechanism (2) preferably located in the side sections of said lower structure (1) which is coupled to an upper structure (3) allowing its movement through the joint and support (6). The axial movement and the upper structure (3) are managed through an automated system based on a programmable automaton and a set of sensors and actuators, namely anemometers and frequency inverters that control these movements. This way, the present invention makes it possible to receive modular constructions, for example houses, making them move, for example, according to the solar orientation, in order to make them energy efficient.

An optimally-angleable solar powered air system is a portable indoor solar heating unit that may stand upright or may be mounted to a door or window. The optimally-angleable solar powered air system has a frame having a solar panel mounted to a first side and a fan mounted to a second side of the frame. In use, the frame may stand inside a room at an angle facing the sun via a removable handle such that the solar panel is able to capture solar energy. The system may then convert solar energy into usable power to power the fan. The second side of the frame includes an air deflector which may direct airflow outwardly from the second side of the frame into the room.

The present invention provides a zero-emission dialysis clinic including a building envelope, daylight concept, lighting concept, mechanical ventilation (71), a chilled and heated ceiling (61) with capillary tubes (60), heat pump (50), and a photovoltaic system (80). Specifically, the present invention balances the energy consumption with energy generation by a photovoltaic system. The CO.sub.2 emissions are thus balanced and the building produces no net emissions.

A tile or plate, includes: an upper plate (3) and a lower plate (4); wherein a plurality of heat conducting cavities (6) are uniformly provided between the upper plate (3) and the lower plate (4) via connecting ribs (5). A solar collection layer is provided on an upper surface of the tile or the plate. Two ends of the tile or the plate are connected with each of the plurality of the heat conducting cavities (6) via transverse connecting pipes (23, 37, 42). The transverse connecting pipes (23, 37, 42) of two neighboring tiles are connected by a ferrule (17) or a hose (36) to form an integrated circulation system. The tile or plate has a large day-lighting area and a high energy conversion rate.
