The invention is a power generator using intermittent fluid flow. The invention facilitates the harnessing of electric power from intermittent wind sources. The apparatus includes panels that are pivotally attached to a frame at a substantially horizontal orientation or are at an acute angle to the horizontal. As wind blows, the panels lift upward relative to the horizontal. Alternatively, the panels may be vertical and attached to an inclined track where the panels move up the track as the wind blows. This motion is transferred to a permanent magnet alternator either via the rotation of a shaft at the pivot point or via a connector rod attached to a leading edge of the panel. The motion may also be transferred by actuating a hydraulic cylinder. This motion pressurizes the cylinder and the pressurized hydraulic fluid may later be transferred into electric power via a hydraulic generator.
