Abstract
An energy generation and storage system that uses a buoyant balloon suspended in a fluid and connected by a tether to a reel. The tether is taut and keeps the balloon from rising due to the buoyant force. A motor can do work to wind the reel in such a way that the balloon is pulled down against the buoyant force. Energy can be extracted from the system by allowing the balloon to rise, pulling on the tether and turning the reel that is connected to a generator. The generator and the motor can be the same unit, or they can be independent units which both connect to the reel.
