Abstract

In an automobile having a primary engine fueled by a primary source of fossil fuel energy, the primary engine and an auxiliary motor device are drivably connected to one or more ground engagement wheels of the automobile. A solar energy collecting device is mounted on the automobile for exposure to solar energy, and has an energy supply mechanism that routes energy collected by the solar energy collecting device to the auxiliary motor device. A control mechanism operates so that either energy is routed from the energy supply device to the auxiliary motor device, or energy is prevented from being routed to the auxiliary motor device.

Claims

1. An automobile comprising:

a primary engine fueled by a primary source of fossil fuel energy, the primary engine being drivably connected to one or more of a plurality of ground engagement wheels mounted on the automobile;

an auxiliary motor device drivably connected to and in coincident rotation with one or more of the ground engagement wheels;

the primary engine, and the auxiliary motor device each being separately drivably connected to a different ground engagement wheel;

a solar energy collecting device mounted on the automobile for exposure to solar energy;

the solar energy collecting device including an energy supply mechanism routing energy collected by a solar energy collecting device to the auxiliary motor device, said energy supply mechanism comprising at least one battery connected to the auxiliary motor device, the battery storing energy collected by the solar energy collecting device and delivering stored energy to the auxiliary motor device;

a control mechanism connected to the energy supply mechanism, the control mechanism being selectively operable between first and second positions wherein energy is selectively routed from the energy supply mechanism to the auxiliary motor device when the control mechanism is in the first position and wherein energy is prevented from being routed to the auxiliary motor device when the control mechanism is in the second position;

an energy regenerator connected to the at least one battery, the energy regenerator being drivably connected to one of said ground engagement wheels driven by the auxiliary motor device, wherein said energy regenerator operates to regenerate energy for storage in the at least one battery in response to rotation of the drivably connected ground engagement wheel when the control mechanism is in the second position.

2. The automobile of claim 1 wherein the energy supply mechanism comprises a photovoltaic material and an electrically conductive cable connected to and delivering energy to the auxiliary motor device.

3. The automobile of claim 1 wherein the primary engine and the auxiliary motor device are drivably connected to a common ground engagement wheel.

4. The automobile of claim 1 wherein the wheel which is drivably connected to the auxiliary motor device is rotatably mounted on an arm which is drivably movable between a ground engagement and a ground disengagement position, the arm being pivoted into the ground engagement position when the control mechanism is in the first position.

5. An automobile having a plurality of ground engagement wheels, one or more of said wheels being drivably connected to a primary engine fueled by a primary source of energy, the improvement comprising:

a solar energy collecting device mounted on the automobile for exposure to solar energy,

an auxiliary motor device drivably connected to and in coincident rotation with one or more of the ground engagement wheels,

the solar energy collecting device including an energy supply mechanism connected to the auxiliary motor device, the energy supply mechanism routing energy collected by the solar energy device to the auxiliary motor device, said energy supply mechanism comprising at least one battery connected to the auxiliary motor device, the battery storing energy collected by the solar energy collecting device and delivering stored energy to the auxiliary motor device;

a control mechanism connected to the energy supply mechanism, the control mechanism being selectively operable between first and second positions wherein energy is selectively routed from the energy supply mechanism to the auxiliary motor device when the control mechanism is in the first position and wherein energy is prevented from being routed to the auxiliary motor device when the control mechanism is in the second position;

an energy regenerator connected to the at least one battery, the energy regenerator being drivably connected to one or more of the ground engagement wheels driven by the auxiliary motor device, wherein said energy regenerator operates to regenerate energy for storage in the at least one battery in response to the rotation of the drivably connected ground engagement wheel when the control mechanism is in the second position; and

the ground engagement wheel to which the auxiliary motor device is drivably connected is mounted on the automobile for controlled movement between a position in engagement with the ground and a position not in engagement with the ground.

6. The improvement of claim 5 wherein the automobile includes a transmission system drivably connecting the engine to one or more of the wheels, the engine driving the transmission and the transmission driving the one or more wheels, the improvement further comprising an interrupt mechanism connected to the control mechanism, the interrupt mechanism suppressing operation of at least one of the engine and the transmission when the control mechanism is in the first position.

7. The improvement of claim 6 wherein the interrupt mechanism is connected to at least one of an engine control circuit and an engine fuel delivery device, the interrupt mechanism suppressing operation of at least one of the engine control circuit and the engine fuel delivery device when the control mechanism is in the first position such that operation of the engine is suppressed.

8. The improvement of claim 5 wherein the energy supply device comprises an electrically conductive cable connected to the solar energy collecting device delivering energy to the auxiliary motor device without intermediate storage of the energy.

9. The improvement of claim 8 wherein the energy supply device comprises a battery connected between the solar energy collecting device and the auxiliary motor device, the battery storing energy collected from the solar energy collecting device and delivering stored energy to the auxiliary motor device.
