Abstract: A pre-sealed anode tube assembly for a sodium-metal-halide energy storage device includes an anode tube and a feed-through current collector assembly at least partially sealed within the anode tube. The pre-sealed anode tube assembly can be independently transported prior to being integrated with a desired sodium-metal-halide energy storage device.

Abstract: An energy storage device includes a housing having an interior surface defining a volume and a plurality of solid electrolyte elements disposed in the volume. Each solid electrolyte element has a first surface that defines at least a portion of a first, cathodic chamber, and a second surface that defines a second, anodic chamber. A plurality of individual anodic chambers are thus provided, at least one of which is evacuated below atmospheric pressure. A majority of anodic chambers can be spaced from one another in a manner that provides a substantially uniform reaction rate throughout the cathodic chamber.

Abstract: A method of assembling a wind turbine blade comprises providing a first blade segment comprising at least two first spar cap segments; providing a second blade segment comprising at least two second spar cap segments; inserting the second blade segment into the first blade segment wherein a spar cap cavity is formed between each set of corresponding first and second spar cap segments; injecting an adhesive into the spar cap cavities to bond the blade segments together, wherein a scarf joint is formed between each set of corresponding first and second spar cap segments.

Abstract: A rotor blade assembly having an access window and methods for assembling a rotor blade are disclosed. The rotor blade assembly may generally include a first shell component and a second shell component. The first shell component may be secured to the second shell component. Additionally, an access region may be defined in the first shell component and/or the second shell component. The access region may generally be configured such that an access window is defined in the rotor blade assembly. The access window may be configured to provide access to the interior of a portion of the rotor blade assembly.

Abstract: A fluid turbine blade is provided. The fluid turbine blade includes a centrally disposed longitudinal spar having a substantially circumferential cross section. The fluid turbine blade also includes at least one rib assembly affixed to said longitudinal spar. The fluid turbine blade further includes a skin attached to the at least one rib.

Abstract: A planar fuel cell stack is provided. The planar fuel cell stack comprises an anode interconnect structure comprising a corrugated first internal manifold connected to a first anode flowfield; a cathode interconnect structure comprising a corrugated second internal manifold connected to a first cathode flowfield; and a thermally active, surface insulated metallic seal disposed between the corrugated parts of the anode and cathode interconnects, such that the thermally active metallic seal responds upon the application of heat to provide sealing between the anode interconnect structure and the cathode interconnect structure.

Abstract: A thermal spray system is provided. The thermal spray system includes a spray assembly for applying a coating to a workpiece. The thermal spray system also includes a fixturing assembly couplable to the workpiece for positioning the workpiece relative to the thermal spray system, wherein the fixturing assembly permits the workpiece to distort during application of the coating to minimize residual strain buildup within the workpiece and reduce coating stresses.
