1. A spark plug comprising: a central electrode;a solid insulator at least substantially concentrically surrounding said central electrode at a terminal end portion thereof;an air gap at least substantially concentrically surrounding said solid insulator at a terminal end portion thereof;an outer electrode at least substantially concentrically surrounding said air gap;wherein a spark gap is formed radially between said central electrode and said outer electrode and includes said air gap and a surface of said insulator such that a Lorentz force is exerted in an axial direction away from said spark plug; anda capacitor formed into said spark plug. 2. The spark plug of claim 1 wherein said outer electrode comprises one or more protuberances. 3. The spark plug of claim 1 wherein an outer plate of said capacitor is electrically connected to said outer electrode and wherein said solid insulator forms a dielectric of said capacitor. 4. The spark plug of claim 1 wherein said capacitor comprises two plates and wherein at least one of said plates is formed from a conductive ink. 5. The spark plug of claim 1 wherein said central electrode is electrically connected to a plate of said capacitor. 6. The spark plug of claim 1 wherein no portion of said outer electrode extends to intersect a path which is axially aligned with a primary axis of said center electrode. 7. The spark plug of claim 1 further comprising an electrical resistor communicably coupled to a plate of said capacitor. 8. The spark plug of claim 7 wherein said resistor is electrically connected such that it resists the flow of electricity during charging of said capacitor, but does not resist the flow of electricity from said capacitor to said spark gap. 9. A spark plug comprising: a capacitor formed in said spark plug;a spark gap formed on a terminal end portion of said spark plug such that a spark produced by said spark plug extends radially and such that a Lorentz force acting on the spark pushes it axially away from said terminal end portion of said spark plug;said spark gap comprising a surface of a solid insulator and an air gap; anda terminal end portion of an outer conductor of said spark plug not projecting radially inward toward an inner conductor of said spark plug. 10. The spark plug of claim 9 wherein said terminal end portion of said a negative electrode comprises a plurality of protuberances disposed on a terminal end portion of said outer conductor. 11. The spark plug of claim 10 wherein said plurality of protuberances comprise at least 3 protuberances. 12. The spark plug of claim 9 wherein said plurality of protuberances comprise at least 5 protuberances. 13. The spark plug of claim 9 wherein a dielectric of said capacitor is formed from an insulator of said spark plug. 14. The spark plug of claim 13 wherein said dielectric, said insulator, and said solid insulator are all connected and are all formed from a single piece of material. 15. A method for igniting fuel comprising: forming a capacitor into a spark plug;forming a semi-surface spark gap such that sparks formed during operation of the spark plug extend radially between an inner conductor and an outer conductor and travel across a surface of a solid insulator and travel across an air gap; andprojecting sparks formed during operation of the spark plug axially away from the spark plug due to the effects of a Lorentz force acting on the electron streams forming the sparks. 16. The method of claim 15 wherein projecting sparks comprises projecting sparks axially away from an end portion of the spark plug by a distance having a magnitude of at least ½ of a closest distance between the inner conductor and the outer conductor. 17. The method of claim 15 wherein projecting sparks comprises projecting sparks axially away from an end portion of the spark plug by a distance having a magnitude that is at least equal to that of a closest distance between the inner conductor and the outer conductor. 18. The method of claim 15 further comprising forming a dielectric of the capacitor from an insulator of the spark plug. 19. The method of claim 18 wherein the same piece of material forms the insulator of the spark plug, the dielectric of the spark plug, and the solid insulator that the spark travels across.
