Abstract

A solar electric vehicle (SEV) with large foldable surface area that can be oriented towards the sun for peak generation of electricity. The surfaces of the SEV are mounted on a flexible chassis for elevation tracking, while the drive train provides azimuth tracking. The SEV also integrates the conversion of power from various sources, to various storage or power consumption devices.

Claims

1. A vehicle configured to collect energy from the sun, comprising;

a plurality of wheels;

a vehicle body configured to hold at least one passenger, the body including at least one upwardly facing solar energy receiving device comprising photovoltaic cells;

a vehicle chassis supporting the vehicle body and comprising an adjustable frame supported upon the wheels, the vehicle chassis frame configured to be selectively elevated at one end of the chassis to adjustably orient the vehicle body and the solar energy receiving device with respect to the sun; and

an adjustment mechanism configured to adjust the vehicle chassis frame so as to adjustably orient the solar energy receiving device with respect to the sun.

2. The vehicle as specified in claim 1 wherein the vehicle body has a plurality of panels, at least one said panel comprising the energy receiving device.

3. The vehicle as specified in claim 2 wherein the vehicle body has at least one side panel comprising the energy receiving device, the side panel configured to be selectively oriented with respect to the sun and adjust an efficiency of the energy receiving device.

4. The vehicle as specified in claim 3 wherein the side panel has a concave surface configured to face the sun.

5. The vehicle as specified in claim 4 wherein the concave surface is parabolic.

6. The vehicle as specified in claim 3 wherein the vehicle chassis has a pair of opposing side panels each comprising the energy receiving device, each said side panel being concave and configured to be selectively oriented and face the sun and adjust the efficiency of the energy receiving device.

7. The vehicle as specified in claim 6 wherein each said concave side panel has a reflective surface configured to direct received sunlight to the photovoltaic cells.

8. The vehicle as specified in claim 3 wherein the at least on side panel has photovoltaic cells configured to receive sunlight.

9. The vehicle as specified in claim 1 wherein the adjustable frame is generally configured as a triangle with a horizontally extending base member, an upwardly extending member coupled to the base member at an adjustment point, and a hypotenuse member coupled to and extending between the base member and the upwardly extending member and opposite the adjustment point.

10. The vehicle as specified in claim 9 wherein the adjustment mechanism is configured to adjust the length of the upwardly extending member.

11. The vehicle as specified in claim 10 wherein the vehicle chassis has at least one side panel comprising the energy receiving device, the side panel configured to be selectively oriented with respect to the sun and adjust the efficiency of solar energy collection.

12. The vehicle as specified in claim 11 wherein the side panel has a concave surface configured to face the sun.

13. The vehicle as specified in claim 12 wherein the concave surface is parabolic.

14. The vehicle as specified in claim 11 wherein the vehicle chassis has a pair of opposing side panels each comprising the energy receiving device, each said side panel being concave and configured to be selectively oriented and face the sun and adjust the efficiency of solar energy collection.

15. The vehicle as specified in claim 14 wherein a rear said wheel is disposed proximate the adjustment point, and at least one front said wheel is disposed proximate where the base member and the hypotenuse member are coupled such that the vehicle can be rotated in a circle about a point proximate the front wheel.

16. The vehicle as specified in claim 15 comprising a pair of front said wheels with an axle therebetween, wherein the vehicle is configured to be rotated in a circle about one of the front wheels or at a point along the axle.

17. The vehicle as specified in claim 14 wherein the opposing side panels are configured to be unfolded downwardly from the hypotenuse member.

18. The vehicle as specified in claim 6 wherein each said side panel is parabolic and is focused at a different focal point.

19. The vehicle as specified in claim 6 wherein one said side panel abuts the other said side panel to form a single parabolic surface having a single focal point.

20. The vehicle as specified in claim 7 wherein the vehicle has a roof panel, wherein the photovoltaic cells are positioned above the roof.

21. The vehicle as specified in claim 6 wherein the vehicle has a roof panel with an underside configured with photovoltaic cells configured to receive energy from the sun.

22. The vehicle as specified in claim 10 wherein the adjustment mechanism is configured to adjust the length of the horizontally extending base member.
