Zusammenfassung:A system having a variable diameter impeller device that is operable for reducing an energy consumption of a rotating fluid or gas pump by increasing said impeller diameter as a speed of said rotating fluid or gas pump increases and decreasing said impeller diameter as the speed decreases. An extendable vane mechanism is configured to move along an elongated curved or sloping slot, said movement along said elongated curved or sloping slot is operable for increasing and decreasing a diameter of said impeller device. A spring mechanism having a first end and a second end extends and retracts to dynamically increase or decrease a diameter of the impeller device.
