Patent ID: 8812224

Claim:
A system for tracking distance traveled by an alternate fueled vehicle using an alternate fuel comprising: programmable circuitry for tracking a distance traveled by the alternate fueled vehicle while under power by only an alternate fuel, the alternate fuel comprising an energy source other than gasoline which powers the alternate fueled vehicle for the distance traveled; the programmable circuitry calculates an alternative fuel credit value associated with the distance traveled by the alternate fueled vehicle while under power by only the alternate fuel; an energy storage unit coupled to the programmable circuitry, the energy storage unit storing the alternate fuel; an internal combustion engine; an internal combustion engine sensor coupled to the programmable circuitry and to the internal combustion engine, the internal combustion engine sensor detecting when the internal combustion engine is being used to power the alternate fueled vehicle for the distance traveled by the alternate fuel vehicle; and a display coupled to the programmable circuitry for displaying the alternative fuel credit value calculated by the programmable circuitry while the alternate fuel vehicle is in operation, the alternative fuel credit value being visible within a driving compartment of the alternate fuel vehicle and located adjacent to a speed indicator for the alternate fuel vehicle to provide a real-time alternative fuel credit value, the alternative fuel credit value changes in accordance with the distance traveled by the alternate fueled vehicle while under power by only an alternate fuel, the speed indicator changes in accordance with any changes of speed of the alternate fueled vehicle, the alternative fuel credit value comprises a monetary value associated with a government currency presented as a numerical value on the display.
