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.

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.

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.

In the light-converting device the light-converting elements (11) are arranged at least on two levels. They are placed on the strips (17). The design is supported at least by one pole (23). Because of it in this device light-converting elements may be arranged on many levels and consequently much less place for it is required and new possibilities appear. The device may be installed for instance on a roof of buildings in the best direction at any side of inclined roof. The device may also be installed on slopes of mountains, in rivers, lakes, coastal zones of seas and oceans, on vehicles, and trailers. The device may be installed on ships standing immovably not very far from the coast and connected to the coast by a cable. The device may be used on military bases, and on the moon. The device is used on military bases will decrease dependence on the fuel supply.

An energy efficient optical window has different optical properties when irradiated by solar light from front or back side of the window. The window is used to reflect most of the infrared light at summer times, leaving the interior cooler and to absorb most of the infrared light at winter times, making the interior hotter by heat transfer from the hot window pane. Mechanical reversal of the window, inside out, is used to apply the needed version for winter and summer. The window is coated with alternating thin metallic and dielectric layers that transmit most of the visible light while reflecting most of the infrared part of the spectrum when impinged by solar light on one side and transmit most of the visible light while absorbing most of the infrared part of the spectrum when impinged by solar light on the other side.

A unitary assembly for an architectural fenestration, providing dynamic solar heat gain control, which (1) provides a track-based frame structure/blind combination in which the blind is self-correcting should the blind material fall outside of the track; (2) provides directional shading, where the assembly provides for dynamically controlling the amount of light allowed to reach the heat storage unit; (3) provides a blind motor without limiter switches and with a quick-release slip-ring; and (4) provides a heat storage unit which is a thermally efficient, transparent and translucent structure, with which gain from sunny winter days is greater than nighttime loss, so as to provide supplemental heat.

Techniques, systems, apparatus and material are disclosed for generating renewable energy from biomass waste while sequestering carbon. In one aspect, a method performed by a reactor to dissociate raw biomass waste into a renewable source energy or a carbon byproduct or both includes receiving the raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction. Waste heat is recovered from an external heat source to heat the received raw biomass waste. The heated raw biomass waste is dissociated to produce the renewable fuel, carbon byproduct or both. The dissociating includes compacting the heated raw biomass waste, generating heat from an internal heat source, and applying the generated heat to the compacted biomass waste under pressure.

Chemical reactors with annularly positioned delivery and removal devices, and associated systems and methods. A reactor in accordance with a particular embodiment includes a reactor vessel having a light-transmissible surface proximate to a reaction zone, and a movable reactant delivery system positioned within the reactor vessel. The reactor can further include a product removal system positioned within the reactor vessel and positioned annularly inwardly or outwardly from the delivery system. A solar concentrator is positioned to direct solar radiation through the light-transmissible surface to the reaction zone.
