A technique facilitates actuating a variety of components in a downhole environment. The technique utilizes displacement based activation of an atmospheric actuation chamber. Activation of the atmospheric actuation chamber may be initiated via a variety of mechanisms, including manipulation of a restraining device, translation of a seal, and/or destruction of a seal. The atmospheric actuation chamber is coupled in cooperation with the corresponding downhole component to enable selective activation of the downhole component.

Methods and apparatus for harvesting energy while moving a tool through a well are shown and described. The harvested energy can be used by the tool to perform work once it reaches an intended location in the well, or along the way. A considerable amount of potential energy is typically lost by oilfield tools as they move down through a borehole. Methods and apparatus described herein recover and/or store some of the energy during the downward movement of the tool.
