Abstract

A fuel tank and a motor vehicle equipped to recapture, store and recycle atmospheric carbon dioxide is disclosed. In one embodiment, such a vehicle includes a fuel tank which stores carbon dioxide in a same area with the combustible fuel of the vehicle. The fuel tank may include one or more pistons, baffles, bladders, or fixed dividers to separate carbon dioxide storage from fuel storage within a fuel tank area. The fuel tank may share volumetric space between carbon dioxide and fuel within the fuel tank. The fuel tank may be integrally formed into a carbon fiber vehicle body. The fuel tank may be integrally formed into a frame of a vehicle.

First claim

The invention claimed is:

1. A fuel tank comprising:
a first storage area for storing a first combustible fuel;
a second storage area for storing exhaust components resulting from burning the first combustible fuel;
a piston disposed intermediate the first and second storage areas for expanding and contracting the respective storage areas, wherein
the first storage area and the second storage area and the piston share volumetric space within the fuel tank.

2. The fuel tank of claim 1 further comprising pistons, baffles, metal walls, carbon fiber walls or bladders which separates the first storage area from the second storage area within the shared volumetric space.

3. the fuel tank of claim 2 , wherein the shared volumetric space is defined by an inner area of an enclosed space or an outer perimeter of the enclosed space.

4. The fuel tank of claim 3 , wherein the enclosed space is at least partially made of at least one of a plastic, carbon fiber, nylon, polyvinylidene fluoride, polyethylene, metal, or a metal alloy.

5. The fuel tank of claim 4 , wherein the enclosed space is integrally formed into a body structure of a vehicle.

6. The fuel tank of claim 4 , wherein the enclosed space is integrally formed into a frame structure of a vehicle.

7. The fuel tank of claim 4 , wherein the inner area of the enclosed space is lined with one or more membranes.

8. The fuel tank of claim 1 , further comprising a third storage area.

9. The fuel tank of claim 8 , wherein a second combustible fuel is stored within the third storage area.

10. The fuel tank of claim 9 , wherein the second combustible fuel is chosen from: nitrous oxide, gasoline, diesel fuel, liquefied petroleum gas, liquefied natural gas, compressed natural gas, alcohol, butane, or hydrogen.

11. A fuel tank method comprising:
providing a first storage area for storing a first combustible fuel;
providing a second storage area for storing exhaust components resulting from burning the first combustible fuel;
providing a piston disposed intermediate the first and second storage areas for expanding and contracting the respective storage areas,
wherein the first storage area and the second storage area and the piston share volumetric space within the fuel tank.

12. The method of claim 11 , further comprising providing pistons, baffles, metal walls, carbon fiber walls or bladders which separates the first storage area from the second storage area within the shared volumetric space.

13. The method of claim 12 , wherein the shared volumetric space is defined by an inner area of an enclosed space or an outer perimeter of the enclosed space.

14. The method of claim 13 , wherein the enclosed space is at least partially made of at least one of a plastic, carbon fiber, nylon, polyvinylidene fluoride, polyethylene, metal, or a metal alloy.

15. The method of claim 14 , wherein the enclosed space is integrally formed into a body structure of a vehicle.

16. The method of claim 14 , wherein the enclosed space is integrally formed into a frame structure of a vehicle.

17. The method of claim 14 , wherein the inner area of the enclosed space is lined with one or more membranes.

18. The method of claim 11 , further comprising a third storage area.

19. The method of claim 18 , wherein a second combustible fuel is stored within the third storage area.

20. The method of claim 19 , wherein the second combustible fuel is chosen from: nitrous oxide, gasoline, diesel fuel, liquefied petroleum gas, liquefied natural gas, compressed natural gas, alcohol, butane, or hydrogen.
