摘要： A structure adapted to traverse a fluid environment exerting an ambient fluid pressure is provided. The structure includes an elongate body extending from a root to a wingtip and encapsulating at least one interior volume containing an interior fluid exerting an interior fluid pressure that is different from the ambient fluid pressure. A method of retrofitting a structure adapted to traverse a fluid environment exerting an ambient fluid pressure, the structure comprising an elongate body extending from a root to a wingtip and having at least one interior volume is also provided. The method includes sealing the elongate body to encapsulate the at least one interior volume containing an interior fluid; associating at least one valve with the at least one interior volume; and modifying interior fluid content via the at least one valve to produce an interior fluid pressure that is different from the ambient fluid pressure.

摘要： A wave energy electric power generation system has a buoyant body responsive to wave movement and an associated, relatively vertically stationary body, a compressor, a pressure regulator, and an impulse air turbine/generator set. The compressor has a piston that moves reciprocally relative to a cylinder to alternately compress air In opposed chambers. A pressure regulator tank defines a chamber in communication with the compressor for alternately receiving compressed air from opposed compression chambers, a floating piston within the tank applying pressure to compressed air in the chamber, a pressure regulator controlling pressure applied by the piston to the compressed air, and an hydraulic dampening system coupled to the floating piston to restrict unwanted vertical oscillations of the piston, for output of a continuous flow of compressed air at relatively constant pressure.

摘要： An energy harvester (10) for use in-line with a pipe (12) to harness potential and kinetic energy of fluids (14) flowing therein. Structure (100) for the energy harvester (10) may include a shaft (126) and a blade (128) extending radially therefrom. The shaft (126) can penetrate a housing that operates as a pipe section (112) to install the device in-line with the pipe (12). The shaft (126) can couple with an electrical generator (134). A load (138) may connect with voltage terminals (180, 182) on the generator (134) so that fluid impinging on the blades (128) will rotate the generator (134) to power the load (138), effectively harvesting power from the flowing fluid (14). In one implementation, a load control device (140) that couples with the generator voltage terminals (180, 182) controls a pressure characteristic of the fluid (14), such as pressure drop, by applying an electrical load on the generator (134) and controllably impeding rotation of the shaft (126).
