    Hmm. Article says one advantage of lasers is that they can ignite the fuel in the center of the cylinder. Doesn't a hemi do that already? Not that there aren't other benefits for lasers. Faster cycle time for one.

    Nope. It still ignites from the edge. By center of the cylinder, they mean away from the edges. Not mentioned is that the design could also split the ignition point into many points. Imagine a floating spark, dead center of the combustion area when a piston is at a specific spot.

    This sounds like a really great idea. With the right kind of lense or refractor a single beam of laser light could be broken into many smaller beams and ignite the fuel all at once. Or multiple lasers in one cylinder could be programmed to fire sequentially to form the desired wave front for various combustion chambers.

    Even with one ignition point, when it's at the center of the gas, that is how the research showed a 27% gain in efficiency. When this tech finally reaches production, it will be a game changer for for fuel economy. Combined with a hybrid power train, I see a very strong future for the ICE. I'd love to see the tech retrofitted to distributor ignition systems with some sort of laser plug that is a direct replacement for a spark plug. That would be awesome.
