Kinetic Energy Harvesting in a Drill String

摘要

An apparatus and method for harvesting energy in a wellbore is disclosed. In one embodiment, a harvester tool positioned in a wellbore for capturing energy in the wellbore is disclosed. The harvester tool includes a rotor comprising a magnet. The magnet is disposed eccentric to a center of the harvester tool. In addition, the rotor is rotatable around the center of the harvester tool. The harvester tool also includes a stator. Rotation of the rotor induces a voltage in the stator.
