摘要:
A system and method is described generally for providing a high altitude conduit the high altitude conduit includes a first material layer forming an elongated duct. The high altitude conduit also includes a second material layer outside the first material layer. The second material layer defines a space between the second material layer and the first material layer. A gas has a density that is less dense than that of the atmosphere outside of the second material layer. The gas is disposed in the space between the first and the second layer. An introducer is configured to provide the gas into the space between the first material layer and the second material layer. The gas causes the conduit to extend in an approximately upright orientation.

A system and method is described generally for providing a high altitude structure including an elongated structure coupled to the ground and extending skyward. The elongated structure at least partially supported by buoyancy effects, the elongated structure including at least one lumen, the at least one lumen configured to transport at least one material and to vent the at least one material to the atmosphere. The system and method also include a gas having a density that is less dense than that of the atmosphere outside of the elongated structure; the gas is disposed in one or more voids of the elongated structure. The system and method includes the use of an introducer configured to provide the gas into the one or more voids. The system and method further include a payload coupled to the elongated structure and being held aloft by the elongated structure.

An energy storage apparatus for storing energy transmitted by a power transmission line includes an elastically deformable component and an actuator-generator. The actuator-generator is coupled to the elastically deformable component such that electrical actuation of the actuator-generator generates tension in the elastically deformable component. The actuator-generator is further coupled to the elastically deformable component such that mechanical actuation of the actuator-generator via a release of tension in the elastically deformable component causes a generation of electrical energy by the actuator-generator.

One aspect relates to a method of reducing noise for an aircraft. The method includes determining a mode of operation of the aircraft or the engine. The method also includes controlling a hybrid jet engine, based on the mode of operation, to at least partially use electrically generated torque to generate thrust.

A method is generally described which includes environmental alteration. The method includes determining a placement of at least one vessel capable of moving water to lower depths in the water via wave induced downwelling. The method also includes placing the at least one vessel in the determined placement. Further, the method includes generating movement of the water adjacent the surface of the water in response to the placing.

A system and method for producing surface deformations on a surface of a body. The system and method relate to changing the convective heat transfer coefficient for a surface. The system includes a first surface being a surface of a body exposed to a fluid flow and at least one actuator affecting deformation of the first surface. The system also includes a control system providing control commands to the at least one actuator, the control commands configured to change deformations on the first surface in order to change the convective heat transfer coefficient of the first surface. Further, the system includes a sensor providing environmental characteristic information to the control system.

摘要:
A system is described generally for providing a structure or structures for altering water surface temperature. The system includes a holding vessel configured to hold water. The holding vessel has at least one wall coupled to a lowermost portion. The at least one wall extends above the water level and the lowermost portion is configured to be submerged. At least one conduit extends from the lower side of the holding vessel. The at least one conduit has a length extending to a depth at which a property of water at the depth is substantially different from that of the water at the surface.
