1. An energy extraction system configured to couple to a rotating surface, the system comprising:
an energy extraction mechanism configured to statically couple to the rotating surface, the energy extraction mechanism configured to revolve about a revolution axis; and a counterweight rotatably coupled to the energy extraction mechanism with the counterweight offset from the revolution axis, the counterweight operable between a cohesive state and a distributed state, the counterweight configured to switch from the cohesive state to the distributed state in response to an applied external force, and from the distributed state to the cohesive state in response to removal of the applied external force. |
