This invention relates generally to power systems, and in particular to hybrid vehicle power systems utilizing hydrocarbon engines and wind power charged batteries to power the vehicle and to supply supplemental electricity to an electrical grid.
The internal combustion engine is traditionally used to power automotive vehicles. Non-polluting alternatives to traditionally vehicles have become increasingly desirable. Alternatives to traditional automotive vehicles include electric powered vehicles and hybrid electric powered vehicles. Drawbacks to electric powered vehicles include not being able to charge the vehicle while in use and not being able to drive long distances between charges. Typical hybrid electric powered vehicles are limited by the size and electric capacity of the batteries. Additionally, with the increasing costs of electricity to power one's home, alternative or supplemental sources of electricity are desirable. Accordingly, there is both a need for alternative vehicle powers systems and for systems to supplement electricity to a power grid.
Embodiments of the invention include a supplemental wind propulsion power system for a vehicle having at least one battery. The system includes an air intake duct disposed on the vehicle for intercepting turbulent airflow created by the forward motion of the vehicle, an air conduit, an air turbine disposed at the outlet of the air conduit and a generator for supplying electricity to the batteries. The system further includes an air filtration system, an air heating system and grid output terminal to provide a port for supplying supplemental electricity to the electrical grid.
Referring now to the drawings, wherein like numerals designate identical or corresponding parts throughout the referred views.
Embodiments of the disclosed supplemental wind propulsion power system 10 and utilization with a vehicle 12 are shown in
Referring to
An air filtration system 22 including an air filter 24 is disposed at the entrance of the air intake duct 18 either within or behind the grill 20 to intercept airborne debris. The air filtration system 22 prevents foreign airborne impediments such as sand, grit, mud, seeds, weeds, feathers, fur or other animal or insect matter from entering the wind power system.
The air intake duct 18 has an adjustable opening 25 including, for example, louvered slats 27 (
Turbulent air flows into the air intake duct 18 and through a penstock or narrowed air conduit 26. Disposed at the end of the narrowed air conduit opposite the air intake duct 18 is an air turbine 28.
The air intake duct 18 and narrowed air conduit 26 preferably include an air heating system 30 (
The turbine 28 includes turbine propellers 44 which are turned by the turbulent air stream flowing from the narrowed air conduit 26. A rotatable turbine shaft 46 fixed to the body of the vehicle is attached to and rotates with the turbine propellers 44. After passing the turbine 28, wind overflow exits through the exit port 40 and back into the environment.
The wind propulsion power system 10 includes an alternator generator 48 having a rotor 50 attached to the rotatable turbine shaft 46 of the turbine 28 for rotation therewith. The rotor 50 includes field poles 52. The generator 48 further includes a stator 56 having conductors 58. The turbine shaft 46 rotates the rotor 50 at varying speeds causing the field poles 52 to move past the conductors 58. This causes electricity to flow and a voltage to develop at generator output terminals 60.
Battery power lines 62 connect generator output terminals 60 of the generator 48 to the at least one vehicle battery 16 to charge or recharge the battery 16 or for supplying power to vehicle systems. The vehicle also includes a grid output terminal connector 64 which is electronically connected at home grid output terminals 65 to the generator 48 to provide a port for supplying supplemental electricity to an electrical grid 66. The grid output terminal connector 64 includes a power inverter connector port 68. The system also includes a sine wave power inverter 70 to convert direct current power from the wind propulsion power system 10 to alternating current for use in the electrical grid 66. The electrical grid 66 may be for a home or other building such as a workplace building, office building or retail building.
