A lighting fixture utilizing light emitting diodes and easily reconfigurable lenses to provide customizable lighting patterns to more efficiently illuminate work or storage areas.

A machine and a process to produce compressed air by sea waves, using the weight of the floating platform with its fixture using its up and down movement to compress air in both directions to absorb the maximum energy of that wave in a direct drive bidirectional pump with a single piston wherein the kinetic energy and wave bouncy force is used to compress ambient air as stored energy. This unique arrangement doubles air volume for compression in both directions in any single wave curve, doubles the energy production in both upper and lower chambers of the pump and multiplies the “psi” based on the float thrust area against the size of the piston in the pump. The preferred embodiment can be used as a stand alone unit as well as in array formation for the desired output 24/7.

A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. Water resistant junctions may be formed between the bases of adjacent shingle assemblies of an array of shingle assemblies. The base may include an insulation layer underlying a water barrier. The base may also include a waterproofing element; the width and height of the barrier may be shorter than the width and height of the waterproofing element.

The present invention discloses an apparatus of converting gravitational energy to electrical energy. The apparatus includes a reciprocating drive mechanism for lifting liquid from a bottom reservoir to an upper reservoir and turbines between the upper and lower reservoirs which are turned by liquid falling down a flow path from the top reservoir through the turbines to the bottom reservoir. The reciprocating drive mechanism includes a large circular ring or wheel pivotally attached at its hub or center to a support frame and a cable over the upper periphery of the ring with two pipes attached one at each end of the cable. The ring pivots back and forth lifting one pipe and lowering the other pipe and vice versa. As a pipe moves down liquid enters the bottom of the pipe while liquid drains out the top of the pipe into the upper reservoir. One of the turbines is connected to the reciprocating drive mechanism and the other to a generator for producing electricity.

System for controlling a door enabling driving from an initial position of its travel in a first direction at a speed v1 as far as a final position, said control system comprising a safety function comprising means for keeping a door in operation despite its having suffered an impact against an obstacle situated on its travel and enabling it to continue its initial movement automatically as soon as said obstacle is removed, through a design reconciling a sufficiently high normal speed of movement v1 of the door with the intention to prevent damage both to the obstacle and to the door by reducing the speed to v3<v1 close to the stored position of the impact.

An oxygen-based biomass solid fuel combustion system and method has an air separator for separating oxygen from air providing a supply of oxygen for feeding oxygen to a solid fuel combustion chamber. An airlock feeds a metered amount of solid fuel to the solid fuel combustion chamber. A burner stage having a firetube for collecting fuel gases from the solid fuel combustion chamber combusts the collected fuel gases with further oxygen from the separator and heats a boiler to generate steam. A heat utilization device (e.g. an electrical generator) may be connected to the steam boiler. Nitrogen-free diluent gases (e.g. argon and carbon dioxide) are used to control combustion process temperatures. The usable heat energy and useful byproducts are extracted from the different stages of the process.

A linear trough concentrates sunlight through a long target window in a greenhouse's roof or north wall. Heat is stored in a geothermal heat bank below the greenhouse's center, where a thermal skirt around the greenhouse reduces heat loss.

A high-intensity LED lighting system is presented whereby one or more LED lighting fixtures are affixed to an elevating structure, the elevating structure having a substantially continuous internal pathway. Said pathway can be used as a conduit or duct for pressurized air which is introduced at or near the bottom of the elevating structure and forced upwardly toward the lighting fixtures so to provide cooling of one or more components of the lighting fixtures so to, ultimately, improve the efficacy of the LEDs contained therein. A method of designing lighting systems, including analysis of whether or not to add air cooling to increase light source efficiency is also disclosed.

A cost-effective and energy-efficient system and method for building construction, such as for residential dwellings and the like, uses dual-wall building envelope system having outer walls and corresponding partition walls spaced outwardly from the outer walls. The envelope system provides ample space for insulation to enhance the thermal efficiently of the house or building, while permitting construction at reduced cost using pre-fabrication methods.

The transparent polycrystalline optoceramic has single grains with a symmetric cubic crystal structure and at least one optically active center. The optoceramic has the following formula: A_2+xB_yD_zE₇, wherein −1.15≦x≦0, 0≦y≦3, 0≦z≦1.6, and 3x+4y+5z=8, and wherein A is at least one trivalent rare earth cation, B is at least one tetravalent cation, D is at least one pentavalent cation, and E is at least one divalent anion. The method of making the optoceramic includes preparing a powder mixture from starting materials, pre-sintering, sintering and then compressing to form the optoceramic. Scintillator media made from the optoceramic are also described.

The invention describes a method of preparing magnetic ferrites from layered precursors in which Fe²⁺ is first introduced into the layers of layered double hydroxides (LDHs) in order to prepare Me-Fe²⁺—Fe³⁺ LDHs, and then by utilizing the easily oxidized nature of Fe²⁺, binary or multi-component ferrite materials containing Fe³⁺ in a single crystalline phase can be prepared. Values of the saturation magnetization of ferrites prepared by the method are significantly increased compared with ferrites prepared by traditional methods. Because the metal elements in the layered precursor have the characteristics of a high degree of dispersion, high activity and small particle size (average particle size 40-200 nm), no milling is required before calcination, thus simplifying the production process, shortening the production period, reducing capital investment in equipment and economizing on energy costs. In addition, the method does not corrode production equipment and does not pollute the environment.

A method for processing a stream enriched in CO₂ from a gas by the action of an absorbent in the stream includes desorbing CO₂ from the stream by application of heat to the stream to desorb the CO₂ and regenerate the absorbent in a reaction system that includes reconstitution of carbon dioxide and an alkanolamine from carbamate and ammonium ion solution. The energy requirement is materially reduced by the presence of a biocatalyst. In another aspect, a gas stream is contacted with a sorbent system to effect absorption of CO₂ from the gas stream, the sorbent and absorbed CO₂ are separated from the gas stream to form a CO₂-rich stream, and the sorbent system contains a primary or secondary alkanolamine and a catalyst selected to modify the reaction kinetics of the absorption process so as to materially increase the proportion of bicarbonate in the CO₂-rich stream relative to carbamate.
