Fords with frickin' laser beams

Unlike traditional spark plugs (invented way back in 1839 by Edmond Berger), laser light may be split into multiple beams distributing ignition points within the cylinders – not just at the tip of the plug. This not only aids combustion, it also lowers emissions during cold starts. Researchers also point out that the lasers use less energy than their spark plug counterparts, eliminate wear items and wires (fiber optics will carry the laser beam to the cylinders), and improve fuel burn by "watching" ignition from within the combustion chamber and sending messages back to the ECU to adjust fuel mixtures, timing, and ignition.
Ford is expected to introduce the technology in its top models within the next few years, and then make it more widely available.
