Cool! thanks for sharing.

I understand the technology and can see how a laser focused into the chamber can ignite the mixture, but how does a laser create a visible "spark" in open air as shown in their video? If that was a laser you wouldn't see the flash of bright light around the lens entry.

Your right, the spark plug creats a spark because the voltage "arcs" across the electrode to a ground, the laser has no where to "arc" to. I also agree I don't think you'd see the glow of light at the entry point, it should be a straight line at the most, but probably unseen.

I have no idea how it works, but could they be dividing the laser's beam inside the "plug" and then refocusing it in the cylinder with the end result being a "spark" so to speak?

That is what I want to know too.

the thing I was wondering about was how they plan to keep the optics clean? have you ever seen the business end of a well-used spark plug?
