Abstract
A generator system powered by a fluid fly-wheel is disclosed that generates electric current to power a tire pressure maintenance and monitoring system. A vehicle wheel including a tire and a rim. A sealed tube containing fluid is fixed around the rim. When the rim accelerates or decelerates, the fluid within the tube moves within the tube a turbine in communication with the fluid is turned by the moving fluid within the tube. The turning turbine drives an electric generator to produce an electric current through induction. In certain configurations, the turning turbine rotates gears to drive a mechanical pump. The electric generator, or mechanical pump may be used to add air pressure to the tire when a sensor indicates low air pressure.
